Abstract
The global maritime industry is continuing the rapid digitization of systems and dependency on advancing technology, in a trend akin to other industrial domains. One of the main issues that this integration has brought is an increased vulnerability to a growing number of cyber threats. While several security measures are being implemented to prevent or respond to cyber attacks, the human element is still one of the main weaknesses. Many of today’s cyber attacks take advantage of human personnel’s lack of awareness, which makes cyber security awareness and training activities of critical importance. Unfortunately, current research is still limited in its offerings for cyber security training specific to maritime personnel. Moreover, such training programmes for the professionals should be developed role-based in accordance with the suggestions of many credited maritime organizations. For this reason, we developed a modular cyber security training programme for the maritime domain called Maritime Cyber Security (MarCy) by implementing Critical Events Model (CEM). Then, we evaluated the MarCy programme by utilizing the Delphi technique with the participation of 19 experts from academia and industry. In this study, we offer cyber security training for seafarers and office employees in shipping companies. We proposed eleven elective modules to improve the knowledge, skills, and attitude of learners against cyber risks. The MarCy programme can be implemented by universities, shipping companies, training institutes, and governmental organizations for maritime cyber security training purposes.

1 Introduction
The maritime industry is a vital sector in global supply chains [134]. Currently, ships perform over 80% of the world trade by volume [134]. Modern vessels are equipped with many automation systems to improve safety and efficiency in operations. However, developing technology in the shipping industry also brought along concerns about cyber risks. Several studies revealed cyber threats and vulnerabilities onboard ships [5], with research highlighting how these vulnerabilities may play a significant role in various maritime incidents as well as financial losses [7, 83, 104]. Accordingly, the International Maritime Organization (IMO) took action, aiming to protect ships from cyber threats. The first proposal came from Canada in 2014 against cyber risks onboard. Canada proposed to be developed voluntary guidelines on maritime cyber security [49]. Afterwards, a resolution for shipping companies was adopted by the IMO. Thanks to the proposal of the USA in 2017[55], cyber risk management became mandatory for ship operators [59]. The human element is also a crucial aspect of risk management and should be carefully considered. Today, millions of professionals work in the maritime sector, with only seafarers numbering nearly 1.9 million professionals [13]. Their cyber awareness is crucial and should be reinforced with training for the effective prevention of cyber risks.
Several organizations (e.g. universities, class societies, and training companies) offer maritime education and training for cadets and professionals in different subjects. One of the domains of this training is cyber security. Cyber security training courses are offered because of occurred cyber incidents in the industry and the requirements of class societies, flag states, and vetting programmes. Even though role-based cyber security training is suggested in credited guidelines [14, 32, 100, 139], a majority of cyber security training programmes offer generic content, with each participant taking the same content in courses. However, each role in the maritime industry requires specific learning needs for cyber security. For instance, a Ship Security Officer (SSO) who could be responsible for cyber security onboard, should get deeper knowledge about cyber risks compared to a second engineer (2/E) [139]. Not only the crew onboard but also staff in companies may have different necessities. For example, purchasing and Information Technology (IT) departments don’t need cyber security knowledge at the same level. Furthermore, the needs of companies are variable. For instance, cyber security requirements in RightShip [115] are unnecessary for a tanker operator. Spending time on getting irrelevant knowledge might be a lost time in business life. Moreover, it might cause conflicts in the minds of attendees.
1.1 Objective, methodology, and novelty
We proposed a modular cyber security training programme for the maritime domain in this study to accomplish the aforementioned issues. The programme was developed using the Critical Events Model (CEM) and was later evaluated through a Delphi technique with the participation of 19 experts from academia and industry. Eleven elective modules were designed for the cyber security training of seafarers and office staff in shipping companies. Moreover, a potential curriculum, instructional strategies, and training materials were proposed in our study. This study also includes discussions of academics and professionals about maritime cyber security training in different dimensions.
1.2 Scope
The study focuses on the development of a modular cyber security training programme for the maritime domain. Even though the programme can be extended with additional modules to cater to various stakeholders in the maritime sector, such as professionals in ports, naval forces, or maritime administrations, this study specifically considers the implementation scenario of cyber security training for seafarers and office staff. The study was evaluated using the Delphi method; however, practical implementation with learner participation was not conducted. The definitions provided by IMO are employed in this study to delineate the terms seafarer and company. A seafarer is defined by the IMO as “any person who is employed or engaged or works in any capacity on board a ship” [48, 58]. The company (also known as ship operator or ship manager) is defined as “the owner of the ship or any other organization or person such as the manager, or the bareboat charterer, who has assumed the responsibility for the operation of the ship from the shipowner and who, on assuming such responsibility, has agreed to take over all the duties and responsibilities imposed on the company by these regulations” [60].
1.3 Structure
This article is organized as follows. Section 2 gives background information to readers. Related works in the literature are investigated in Sect. 3. In Sect. 4, the methodology employed in the study is described in detail. Section 5 presents the MarCy programme for maritime cyber security training. The evaluation of the programme and discussions about maritime cyber security training is given in Sect. 6. Finally, Sect. 8 offers a summary and recommends additional research questions for further investigation.
2 Background
In this section, we present a comprehensive discussion and analysis of the current availability of maritime cyber security training. To achieve this, we conducted extensive research, which involved careful examination of relevant academic studies and utilization of search engines to identify institutes offering maritime cyber security education and training to cadets and professionals. Additionally, we sought out guidelines and questionnaires that include requirements and recommendations for maritime cyber security training.
The results of our investigation revealed that numerous training institutes provide maritime cyber security training programmes. However, we observed that some of these programmes lacked sufficient details about their courses. To ensure the quality and relevance of our study, we focused on those institutes that provided comprehensive information, which could be valuable for our research. Furthermore, we took into consideration previous studies that had already referenced certain institutes’ training offerings, and we duly reviewed and cited them to avoid unnecessary duplication of analysis. Through meticulous examinations, we thoroughly analysed the objectives, learning outcomes, curriculums, modalities, and target groups of various training and education offerings in the maritime cyber security domain.
Moreover, we extensively reviewed maritime guidelines, paying special attention to their recommendations concerning maritime cyber security training. This process provided us with valuable insights, particularly regarding suitable modalities and curriculums. We have included these insights in our study and recommended them as valuable training materials in subsequent sections.
Lastly, we also examined questionnaires from vetting programmes, which included recommendations or requirements for cyber security training from maritime companies. The findings obtained from this analysis were instrumental in designing our comprehensive training programme.
In conclusion, our study encompasses a thorough assessment of maritime cyber security training, drawing information from a diverse range of sources. By relying on extensive research and analysis, we have aimed to make a well-informed and valuable contribution to the field of maritime cyber security education and training.
2.1 Training institutes
In this section, institutes providing maritime cyber security training are in place. Relevant institutes were accessed using the ((“maritime”) AND (“cyber security”) AND (“training”)) search string on the Google search engine. Only institutes that have published their training curriculum were considered. The search revealed many institutes offering maritime cyber security training, with a particular focus on training provided by universities in this section. It is important to note that the institutes offering maritime cyber security training worldwide are not limited to those listed in this section.
Solent University offers three courses regarding maritime cyber security. The course of Proficiency in Cyber Security Hygiene [128] takes two hours and is given online. The course is convenient for crew members and shore staff. An introduction, best practices and overview of basic cyber security principles are involved in the course. Phishing attacks, password security, and safe use of the internet are given in this course. Furthermore, best practices defined by the UK’s Maritime and Coastguard Agency (MCA) [43] and Government Communications Headquarters (GCHQ) [41] are offered. Solent University also offers the Ship Cyber Security Officer course [129] to give required knowledge to cyber security officers onboard and key personnel in maritime companies. The course aims to enhance cyber security awareness, and give required knowledge about types of vulnerabilities, types of threats, and risk management, including risk identification, protection and recovery manners. This course also includes best practices defined by MCA and GCHQ. Participants should complete the Proficiency in Cyber Security Hygiene course, before undertaking the course. The last course offered is Cyber Security for Maritime Professionals [125]. It takes three days and is given on-site. The course was developed for crew members and shore staff to improve cyber awareness about attack types, concepts, and techniques. The course also introduces the EU NIS Directive, ISO 27000 standards for information security, computer system design and networks, methods of protecting data, maintaining privacy, and system integrity. At the end of the course, the participants gain CISCO Introduction to Cyber Security certificate.
The Estonian Maritime Academy organized a summer school for maritime cyber security in 2018 [132, 140]. The summer school was suitable for both professionals and researchers from the IT and maritime fields. The course aimed to enhance awareness about cyber threats and vulnerabilities in the maritime industry. An overview of the tools and communications used in the shipping industry and the cyber risks of autonomous ships were given in the summer school. Moreover, the course led to experience sharing among participants. The academy also offers a BSc-level course entitled Introduction to Cyber Security [131]. The objective of the course is to give a cyber security overview and related risks to ships, organizations and individuals. The course is compulsory for cadets in the navigation and ship engineering departments and is elective for students in the port and shipping management department. The course takes a semester to complete and covers the cyber security terminology, main cyber risks and threats, familiarization with relevant guidelines, best practices of cyber hygiene, and ethical aspects of cyber security.
The Norwegian University of Science and Technology (NTNU) in Norway provides a course titled Maritime Digital Security for master students [96]. The course offers an introduction to maritime digital security, handling of digital vulnerabilities, and implementation of cyber risk management. The course is held intensively over two weeks in a semester. Students go through lectures, group work, and simulator exercises. Moreover, students should make a presentation to complete the course. Typical threats and defence techniques, challenges associated with digital security management, and theories related to digital security management and risk management are provided to students in this course.
Plymouth University is another academic institute offering a cyber security course for the shipping industry [135]. The course titled Cyber Security Awareness for Seafarers takes one day and is delivered on the main campus of Plymouth University. In-house training options are also available.
Universities also offer formal education in master’s degrees specifically developed for the maritime cyber security domain. BSA College in Greece offers a Maritime Cyber Security master’s programme [11]. The French maritime academy, Ecole Nationale Supérieure Maritime (ENSM), also offers a master’s programme, entitled Cyber security for Maritime and Port Systems [35]. Relevant maritime regulations and computer networks are available in the curriculums of both programmes; however, other contents are variable. The digitalization of shipping, general principles of computer operating systems & virtualization methods, maritime cyber security reviews, assessments and audits, cyber security principles, and maritime cyber security management systems, are given in BSA College. ENSM provides the contents of basic knowledge and introduction to maritime cyber security, cyber security of tidal power projects, cyber defence including detection, reaction, resilience, cyber security of industrial systems and components, and integration of cyber security in maritime projects.
The class society, Registro Italiano Navale (RINA), provides a cyber security course for professionals working in the maritime industry [116]. The course aims to improve cyber awareness onboard and to support office staff in establishing procedures and plans. The course is given online but live. The course curriculum consists of risk identification and response, detecting suspicious activities, reporting cyber incidents, understanding preventative maintenance routines, and such.
The Indian Register of Shipping (IRClass) offers Cyber Security Internal Auditor Course for mariners and IT experts [62]. The participants can get sufficient knowledge to be ready to fulfil cyber security requirements in the International Safety Management (ISM) Code. It takes one day to complete the course. The essential topics of the course are ISM code requirements, cyber risks, reference standards, implementation of cyber risk management procedures, and verification of the implementation of such procedures through an ISM internal audit.
The IMO-recognized organization, the Nautical Institute, in collaboration with HudsonCyber offers the course titled Maritime Cyber Awareness for Seafarers [94, 95]. The course is designed for seafarers. It is given online and takes approximately three hours to complete. The course consists of three objectives: rising cyber security awareness in shipping, helping seafarers to identify potential cyber risks in operations, and educating seafarers about reporting cyber incidents. The curriculum of the course comprises the definition and importance of cyber security, cyber threats and risks, human factors, trust factors, identifying and reporting cyber incidents, best practices, and maritime cyber security scenarios.
Maritime Training Services (MTS) [92] also provides an online cyber security training course to familiarize seafarers with cyber threats in the maritime industry and the detection and prevention measures of such threats. To this end, the course developed includes the topics of creating a strong password, phishing attacks, malware hiding e-mail attachments, safe use of social media, and key tips to improve vessel cyber security.
Maritime Trainer offers maritime-related courses to shipping companies. One course offered for seafarers and office staff is Cyber Security [133]. It is given online and takes nearly two hours. The course curriculum includes the core notions of cyber security, cyber systems onboard ships, some types of malware (e.g. spyware and ransomware), phishing attacks, secure passwords, wireless network security, and the importance of the usage of antivirus and firewall software.
Many providers other than the aforementioned are available for maritime cyber security courses. Lee et al. [75] and Lee et al. [76] examined some of them, such as Det Norske Veritas (DNV) [30], LR [80], Aboamare [1], Aspida, CBS [19, 20], JWC International, KR [71, 72], Maritime Institute of Technology and Graduate Studies (MITAGS) [87, 88], SEANET, Ocean Technologies Group (Videotel) [99]. However, some of them (e.g. CBS, MITAGS, ASPIDA, and JWC International) might no longer offer such courses.
Class societies, universities, maritime associations, and private companies offer online, online live, on-site, and video training for cyber security. The courses are suitable for any professional in the maritime industry, such as IT experts, seafarers, and office employees. The courses typically aim to reply to the necessities of the industry. On the other hand, master’s programmes aim to educate domain-specific experts. The training courses are typically given as a lecture modality. Other training methods, such as group discussions, case studies, and demonstrations, are missing in general. Bridge simulators for cyber security training purposes are used in NTNU’s MSc-level course and Estonian Maritime Academy’s summer school. The summer school also includes practical exercises, such as the use of Open Source Intelligence (OSINT) techniques and hacking tools [79].
Limited information about the curriculum exists for many courses except the master’s programme provided by BSA College and the training course offered by RINA. However, RINA’s content list is very similar (even the wording used) to suggestions of a guide [14]. The training courses generally include safe use of the internet, phishing attacks, creating secure passwords, ISM Code requirements, and cyber risks of mobile phones and removable media. Additional content is variable by the preference of course providers.
The short courses can be typically completed in a day. Estonia Maritime Academy offers a semester-length course for BSc students. Although NTNU’s cyber security course for MSc students is also for a semester, it takes intensively a 2-week period in a semester. Solent University offers three types of courses for different objectives and one of which is to train Ship Cyber Security Officers (SCySO). There is no alternative to this course. In the course of Cyber Security for Maritime Professionals [125], a CISCO Introduction to Cyber Security certificate is issued for attendees. IRClass offers an auditor course and focuses on internal audits for ship and office sides in compliance with the ISM code requirements. Table 1 represents attributes of courses described in this study except for master’s programmes. Additional courses and comparisons can be found in the papers of [75] and [76].
The IMO’s Resolution MSC.428(98) comprises compulsory cyber security requirements [59], which are mentioned in training courses. However, recommendations from the International Ship and Port Facility Security (ISPS) Code might be overlooked [50]. Similarly, regional requirements and recommendations are often omitted. It is important to acknowledge that covering all official documents issued by flag states is a challenging task in a training programme. Nevertheless, it is feasible to include explanations of circulars from select countries, especially those relevant to participants’ operations.
The curriculum of many training programmes lacks guidance on developing a cyber security plan, including risk management. Notably, crucial commercial aspects are also missing, such as the cyber attack exclusion clause in marine insurance policies (i.e. CL380), investment recommendations, and vetting requirements. While training providers acknowledge the importance of cyber security in vetting programmes [28, 30, 133], the syllabuses for such training often lack comprehensive information on potential deficiencies, requirements, and recommendations.
Some training courses adopt a role-based approach (e.g. tailored for IT experts, office employees, and seafarers). However, the responsibilities of each employee vary significantly; for instance, an engineer and an officer are accountable for different onboard systems. Therefore, role-based training programmes should be more specific and tailored to the distinct responsibilities of individuals.
Furthermore, the practical application part of training courses, such as updating the operating system, is generally overlooked. During our study, we encountered challenges in addressing these gaps and providing comprehensive coverage of the subject matter.
2.2 Guidelines and questionnaires
The IMO recommends following the Guidelines on Maritime Cyber Risk Management [14] to prevent cyber risks onboard ships [56, 57, 59]. As per the guideline, training and awareness are the key elements to avoid cyber threats and vulnerabilities. Moreover, the guideline states “an awareness programme should be in place for all onboard personnel according to their role”. Furthermore, training awareness should be given at the appropriate levels to onboard personnel and shoreside personnel. As per the guideline, marine human resource managers should be responsible, and the safety manager, fleet manager, and training manager should provide the required support for crew cyber risk management training. The awareness programme should cover maintenance routines (e.g. antivirus, patching, and backup), e-mail risks (e.g. phishing attacks), risks related to the use of the internet (e.g. social media and cloud storage), risks of the use of own devices (e.g. removable media), risks related to publicly available geolocation data, risks of working third parties alone (without supervision), procedures for the use of third parties’ removable media onboard, reporting procedure of cyber incidents, improving awareness about the impact of cyber attacks on safety and operations of the ships, and safeguarding passwords.
The Cyber Security Workbook for on Board Ship Use [139] includes recommendations for the training of seafarers. Cyber security training is also suggested to the office staff who frequently visit ships, such as superintendents. Role-based cyber security training is suggested in the workbook and the mutual parts in the training of seafarers and office staff visiting ships should comprise the use of ship business network, recognizing malware attempts, safe use of the internet including phishing attempts via e-mails, safe file sharing onboard, cyber risks posed by ship visitors, the use of personal devices onboard, safekeeping passwords and sensitive information, the procedures for the use and update of software including antivirus, secure remote connection for software assistance, response plan including reporting procedure. The seafarers should be also aware of signs of a potential cyber incident, such as slow systems, network connectivity problems, changes in software settings, software errors and crashes, and unexpected changes to passwords. The workbook also gives detailed information about the evaluation of crew, designing a training programme, and cyber security drills.
The Implementation Guide for Cyber Security on Vessels [32] published by Digital Container Shipping Association (DCSA) states two types of training. One of which is generic cyber security training for all crew members. This training may include basics of cyber risks onboard, such as phishing attacks and the dangers of using memory sticks. Another training is regarding incident response for the appropriate crew members. The training content could be tailored role-based. The context may include contacts, forensics, reporting, system recovery, restoration, and such.
The Guide for Cyber security Implementation for the Marine and Offshore Industries [2] published by the American Bureau of Shipping (ABS) includes explanations and requirements for the cyber security class notations, such as CS-System, CS-Ready, CS-1, and CS-2. The CS-1 and CS-2 are regarding the companies and request documented records for cyber security training concerning cyber hygiene and support of specialized cyber security functions. Specialized cyber security training other than generic is also requested. For instance, the training for IT and Operational Technology (OT) staff should involve the impacts of disruptions of critical IT and OT systems on personnel and environmental safety.
The Guidelines on Maritime Cyber Safety [63] published by IRClass provides information and requirements for the cyber security class notations titled Informed Cyber Safety (CyS-I) and Advanced Cyber Safety (CyS-II). IRClass expects training to improve cyber awareness. The employees should be trained initially and periodically. Training requirements for cyber safety, such as internal threats, lessons learnt, maintenance routines (e.g. patching and updating), backup and incident response procedures, and external cyber information should be identified. The employees should be notified about updated information on cyber safety. Senior management should be trained about the impacts of cyber incidents on legal and business dimensions.
Cyber security training for seafarers is verified in the vetting inspections by vetting inspectors, including Ship Inspection Report (SIRE) and Chemical Distribution Institute (CDI) inspections. As per the CDI questionnaire [21], the crew should be trained on company procedures to prevent cyber risks, including the use of memory sticks and personal devices, the limitations on the use of equipment, and response procedures in case of a cyber attack. Training films should be shown and crew-specific training should be provided as per the SIRE questionnaire, however, no content suggestion for training is in place [100].
The suggested training contents in the guidelines are typically based on cyber awareness and IT security. Phishing attacks, creating a secure password, and secure use of memory sticks and the internet are highlighted. The importance of crew-specific and periodic training is emphasized. Drills are suggested, but details regarding drills are too limited. One of the important roles in our study is Cyber Security Officer (CySO) and is well defined with potential responsibilities in [47]. According to the guide, the CySO can be assigned to the company office, ship, or both sides, depending on the type of the ship and the fleet size. IRClass also underlines SCySO and Company Cyber Security Officer (CCySO) in its guide [63]. Thus, we also decided to identify two roles as CCySO and SCySO in our study. [65] focuses on a risk assessment for shipboard OT systems, including communication, navigation, cargo management, and machinery systems. The guide is significant to understand potential risks onboard. All such guidelines [14, 32, 37, 47, 61, 65, 86, 139] highlight the importance of awareness to prevent cyber risks, and effective training is strongly suggested for crew and office employees. Moreover, such guidelines look from a broad perspective and give information in technical and procedural dimensions regarding maritime cyber security. Not only guidelines mentioned but also the book written by Kessler and Shepard [70] explains different aspects of maritime cyber security in detail, such as the basics of cyber security, case studies, and strategies for maritime cyber defence. [14] and [139] propose a detailed content list for the training. We took into consideration the contents of such sources while preparing our training curriculum. Several checklists are also offered by [139] to verify the effectiveness of the training. Sources mentioned here don’t explicitly reply to questions regarding the training of who should give, how should be given, how long should take, and how often should be repeated. All materials mentioned in this section can be used as training material in a maritime cyber security course.
3 Related work
In this section, we reviewed scientific papers and research projects related to maritime cyber security training and education. We used search string ((“maritime”) AND (“cyber security”) AND (“training”)) to identify relevant studies in the literature. The literature review was conducted using reputable digital scientific libraries, including the Institute of Electrical and Electronics Engineers (IEEE) Xplore, ScienceDirect, SpringerLink, and the Association of Computing Machinery Digital Library (ACM DL). As Google Scholar and ResearchGate provided relevant search results from other scientific databases, we also utilized them. The selection of publications was based on a sequential review of the title, keywords, abstract, conclusion, and the full text of the publications. Furthermore, to access additional publications, we reviewed the bibliographies of the selected publications for back tracing. Citavi software [81] was used to extract data from the articles and manage the acquired knowledge. Objectives, learning outcomes, modalities, curriculums, target groups, advantages and drawbacks of training proposals were extracted. Findings collected in the literature review were later used to design MarCy training programme. Moreover, methodologies for developing a training course were investigated to determine the best method for our research objective. To the best of our knowledge, there are currently no other programmes specific to maritime cyber security training in the literature. That being said, a number of awareness and training activities for maritime and maritime security have been proposed over the years.
The International Association of Maritime Universities (IAMU)’s research project, Addressing Cyber Security in Maritime Education and Training (CYMET), aimed to enhance cyber awareness in the maritime industry through education and training [4]. In the context of cyber security, the training necessities of seafarers were evaluated and recommendations for maritime education and training were provided. Web-based training was suggested through two platforms (i.e. Moodle and Itslearning). The learning package consisted of seven lessons, such as introduction, understanding cyber threats, awareness across the organization, elements of cyber security management, good practices, rules, standards and guidelines, and examples from real life. The package also included an extension with lessons on network integrity, Global Positioning System (GPS) jamming and spoofing attacks, and safe information exchange. Their web-based learning course was tested by a pilot group involving cadets in the project partners. After completing the course, feedback was received by answering several questions. The received replies revealed that the developed course was effective and interesting for the attendees.
Lee et al. [75] offered a training course for the SCySO. Their course proposal comprised a curriculum of 16 h (two days). The curriculum included 23 sections, such as IMO and vetting requirements (i.e. RightShip and Tanker Management and Self Assessment (TMSA)), recent incidents, roles and responsibilities of SCySO, risk assessment, and good practices. The training methods were lectures, presentations, group discussions, and case studies.
Lee et al. [76] proposed cyber security familiarization training for all seafarers. According to their proposal, the training should be added in “Section A-VI/6 Mandatory minimum requirements for security-related training and instruction for all seafarers” in the Standards of Training Certification and Watchkeeping (STCW) Code [52]. The curriculum should cover various aspects, including types and principles of cyber threats, kinds of cyber attacks, the technology of target systems, networks, and equipment, assessment of cyber risks, methods to mitigate cyber risks, development of contingency plans, and best practices based on actual incidents.
Kuhn et al. [73] explored a cyber security exercise at the North Atlantic Treaty Organization (NATO) Centre of Excellence, where participants faced maritime cyber scenarios to assess risk perception and response. Key findings: 1) Group risk perception was effectively evaluated by aligning risk with sector guidelines in a group setting. 2) As incidents escalate, those with public/military experience and mixed cyber security expertise prioritized private sector responsibility and visibility but not urgency. The exercise aided robust cyberspace operations, emphasizing risk assessment’s crucial role. Successful small-scale trials offered capacity-building insights and highlighted the need for joint response to maritime cyber incidents.
Adams et al. [3] reviewed current port security approaches and the cyber-physical security threat, assessing how new systems like Scalable multidimensionAl sitUation awaReness sOlution for protectiNg European ports) SAURON could reduce vulnerabilities. The SAURON hybrid situational awareness tool was developed to detect combined physical and cyber attacks, providing decision-makers with integrated situational awareness and supporting effective countermeasures. The paper emphasized the benefits of such approaches and highlighted the need for security technologies to be complemented by effective processes and personnel with appropriate training. Multidisciplinary training is crucial in combating complex cyber-physical security threats. The study demonstrated how industry and academia-developed technologies can enhance port security, emphasizing the importance of training and awareness in addressing these challenges.
Odessa Maritime Academy is actively involved in the “Trainings in Automation Technologies for Ukraine” project, focusing on modern technologies and cyber security implementation in the maritime field. Shapo and Levinskyi [120] highlighted the need for deepening IT learning in various areas like data transfer technologies, computer control systems, and remote control protocols. Additionally, the significance of cyber security education and e-learning technologies was emphasized. The university had well-equipped labs and an e-learning system to facilitate students’ access to teaching materials. Courses cover disciplines related to the mentioned areas, benefiting at least 200 students annually. The author possesses experience in industrial cyber security devices adjustment and integration, enhancing the effectiveness of training. The potential audience includes numerous crewing and shipping companies in the region, given Ukraine’s considerable seafarer population.
Hopcraft [44] emphasized the link between seafarer training and maritime safety, advocating the development of standardized digital competencies for all seafarers. The complexities of maritime operations and various levels of responsibility make creating standardized competencies challenging. Three levels were identified: Support, Operational, and Management, each requiring specific cyber risk management competencies. Equipping seafarers with appropriate digital competencies ensured awareness of digital system risks and the ability to respond effectively. The NIST Cybersecurity Framework’s core functions (Identify, Protect, Detect, Respond, and Recover) were applied to these levels to guide organizations in understanding required competencies. Overall, this paper aligns NIST framework with seafarers’ roles at different levels to define essential cyber security competencies.
Olivier et al. [66] presented a high-end hybrid cyber range for port cyber risks awareness and training, focusing on a specific port use-case and achieved results. The Cyber-MAR project demonstrated the topology of a port’s critical infrastructure with real cyber-physical systems and devices. The cyber range aimed to simulate cyberattacks to detect, mitigate, and train personnel for crisis management. During a pilot demonstration, the importance of dynamic prevention and reaction measures was emphasized. The Cyber-MAR H2020 project’s main objective was to develop innovative environments to simulate realistic cyberattack scenarios and train personnel. The project included a Training Layer with a Learning Management System (LMS) module to improve training performance and experience, providing course catalogues, assessments, and individualized assignments.
Lovell and Heering [79] summarized the findings in the Exercise Neptune organized by Tallinn University of Technology (TalTech) in 2018. The master’s students and PhD candidates attended the exercise. A full mission bridge simulator was used in the exercise. The study uncovered that daily orders and confidential orders could be found on Twitter, and NATO warships could be tracked using social media platforms (e.g. Facebook, Twitter, and Snapchat). The study revealed the importance of cyber awareness, training, and misuse of social media at sea. The paper also uncovered that individual information breaches could lead to the whole landscape which might be exploited by malicious actors.
Bacasdoon and Bolmsten [10] investigated four maritime education and training institutes (METI) offering maritime cyber security courses to seafarers. A total of 29 knowledge items and 16 skill items have been provided by four METIs. The courses have been given online or blended (i.e. the combination of online and on-site training). One of the METIs has focused on improving only knowledge. The others have aimed to improve the knowledge and skills of the attendees. All METIs except one have made a test to assess participants after the completion of the course.
Potamos et al. [111] introduced a maritime cyber range training environment designed to simulate offensive and defensive actions in maritime cyber security. The environment included various components like navigational, information, and telecommunications systems, as well as networks and Supervisory Control and Data Acquisition (SCADA) systems. It enabled scenarios such as vulnerability testing, penetration, exploitation, traffic eavesdropping, Global Navigation Satellite System (GNSS)/Automatic Identification System (AIS) spoofing, navigation takeover, and signal intelligence. The cyber range could simulate or emulate Information and Communication Technologies (ICT)/OT systems, providing a realistic setting for cyber security training and research. It aimed to improve situational awareness for ship crew members and onshore operators, aligning with cyber security initiatives and regulations in the maritime domain. Overall, the maritime cyber range contributes to the enhancement of maritime cyber security.
During the literature review, it was seen that developing a methodology for designing a training programme attracted the attention of many researchers. Several models have been proposed to develop a training course [9, 16, 18, 42, 74, 85, 93, 103, 110, 113, 119, 130]. Moreover, review studies for such models and methodologies are available [24, 33, 98].
Ornstein and Hunkins [103] suggested six steps for curriculum design, such as considering curriculum assumptions regarding objectives, participants’ needs, various design components and their organization (e.g. content), sketching out design components, cross-checking design components, and sharing the curriculum design with a colleague. Aris et al. [9] proposed a framework for assimilating multidisciplinary programmes in the curriculum structure. The proposed model in the study consists of four stages, such as the identification of elective courses, discussion with faculties and branch campuses, marketing and promotion, and assimilation in curriculum review and development of the new programme. Another model, the High-IMPACT Training Model, was proposed by Sparhawk [130]. The High-IMPACT consists of six steps, such as identifying training needs, mapping the approach, producing learning tools, applying training techniques, calculating measurable results, and tracking ongoing follow-through.
Chowdhury et al. [22] proposed a framework for modelling cyber security training exercises based on concepts of personalized learning theory. The framework uses a revised, five-step ADDIE model for the analysis, design, development, implementation, and evaluation and feedback components. The main purpose of this framework is to tackle the issue of training offerings often being considered not engaging by participants. The authors propose a solution that accounts for the preferred training method, and contents, and conducts thorough evaluation and feedback collection. To account for the participants’ requirements and preferences when it comes to training, trainees are involved in all phases of development. This is mainly achieved via feedback collection.
The training models reviewed generally consist of three mutual dimensions, including identifying the needs, building a curriculum, and verification of the model. Several ways are proposed for the verification of a training model. For instance, implementation primarily on a pilot group, discussion with colleagues, or assessing the participants’ performance.
As observed, the models for developing a training course are typically proposed for formal education at different levels (e.g. high school or undergraduate studies). Training for professionals is typically not mentioned as an application area of the methodologies in the analysed studies. This represents a significant challenge in the cyber security awareness and training domain, as training professionals require additional consideration, and the previous models would need to be modified and validated for the training of professionals.
4 Methodology
Several models for designing and developing training have been proposed over the years. The Critical Events Model (CEM) [93], initially developed in 1965 under the title “Process of Training” by Leonard Nadler, in 1982, stands out as one of the most well-established and thoroughly described methods in training design. It is also commonly referred to as Nadler’s Model [36]. The CEM provides a comprehensive approach to designing any types of training courses, applicable not only to formal education but also to the diverse training needs of various organizations. Its versatility makes it particularly suitable for industries experiencing rapid changes [93]. As of now, the STCW does not include any specific requirements or recommendations to enhance the cyber awareness of seafarers. Consequently, seafarers usually receive cyber security training during their professional careers. To address this gap, our study has incorporated the CEM with several modifications, including the addition of a modular approach and changes to the evaluation step.
In the modular training approach, relevant parts of a training structure are offered to learners by considering personalized training needs. This approach has been performed over the years for different training needs [27]. It is especially effective for vocational training [38]. Given that only required knowledge is provided to attendees by considering their learning needs, it does not cause lost time in business life. That is why modular training is a cost-effective method and can be given online, as well [123]. It provides flexibility to the training designer and learner. The designer can offer new qualifications for trainers by adding new modules, so changing training needs of the industry can be simply responded [38].
As mentioned in Sect. 3, credited organizations in the maritime industry [14, 32, 100, 139] suggest role-based cyber security training. To respond to this recommendation, we sought to bring a modular approach to the MarCy programme. This allows professionals in the maritime domain to take only the required modules of the training based on their roles and responsibilities. By developing modules, the training needs of any professional in the maritime domain, such as seafarers, office staff, port employees, and navy personnel, can be met through specialized cyber security training. In other words the application scope of the programme is expanded. To bring a modular approach to MarCy, we slightly modified Step 1 (i.e. Identify the Needs of the Organization) and Step 3 (i.e. Identify Learner Needs) of CEM. Similar to CEM, MarCy also aims to define the organization’s needs in Step 1. However, in MarCy, these needs concurrently define the training modules. In Step 3, MarCy, like CEM, analyses the specific training needs for each role. Additionally, in MarCy, roles and training modules are matched at this step.
In addition to the mentioned modifications to incorporate a modular approach into MarCy, another change was implemented in Step 9 (i.e. evaluation and feedback). The CEM includes a self-evaluation phase, which is performed after each step by discussing with internal and external experts. In practice, this translates to conducting a minimum of eight meetings with experts for the evaluation of a training programme under development. As explained in Sects. 6.3 and 6.7, the number of experts on maritime cyber security globally is still limited. Moreover, arranging meetings with selected experts would prove to be another challenge, both in terms of scheduling and due to time restrictions for training development. For these reasons, we replaced the self-evaluation phase of CEM with our evaluation approach (i.e. Step 9: evaluation and feedback) as described in Sect. 5.9. Simply, while CEM mandates the implementation of the "evaluation and feedback" step after each step, MarCy does not require this. Unlike CEM, MarCy programme, already designed with expert input, enables the enhancement of training effectiveness through simpler modifications tailored to the unique needs of learners. This is achieved by soliciting opinions exclusively from internal stakeholders. Our proposed approach still relies on feedback from relevant stakeholders, but it targets only internal stakeholders to the training, such as learners. This approach facilitates data collection and also ensures that the developed training is well-tailored and targeted to training participants.
The objectives of the other steps in MarCy align with the objectives of CEM, however, these other steps are individually applied for each training module in MarCy. Consequently, we propose MarCy programme for maritime cyber security training as represented in Table 2, outlining the implementation phases.
The MarCy programme comprises a total of nine steps. Additionally, the Delphi technique was performed to evaluate the effectiveness and usability of the MarCy programme by considering the needs of maritime cybersecurity training programmes, as illustrated in Fig. 1. In other words, Delphi was solely performed to evaluate the MarCy programme in our study. Course designers don’t have to implement Delphi while following the MarCy programme.
The Delphi technique is considered in the literature as a well-suited research instrument to obtain judgement and opinion on incomplete knowledge about a problem or phenomenon [124]. The method generally comprises an iterative process with the goal of collecting feedback on a given topic from a selected, anonymous panel of experts on a topic. Recent adaptations of the method allow for additional flexibility in its implementation. The decision of using the Delphi method as a validation technique for the MarCy came from its ability in collecting weighted feedback from the panel of experts and allow for open debate, without requiring practical methods of evaluation, such as experimentation. The panel was selected based on stakeholder analysis for cyber security training for the maritime sector, with the goal of finding a sufficient amount of experts for each of the following profiles;
-
academics who work in the field of maritime cyber security;
-
senior industry experts who are responsible for maritime training, including maritime cyber security training;
-
senior industry experts who are responsible for the Safety Management System (SMS) of companies, including maritime cyber security policies and procedures.
A total of 37 invitations were sent to relevant stakeholders. The final selection came down to 19 participants with their details represented in Table 3. Some of the academics and experts in our group have a background in sea service as a master, officer, or engineer.
Two rounds of Delphi were conducted in total, with additional questionnaires answered by participants who could not participate in the previous rounds. While Appendix 1 presents the fundamental questions, it’s important to note that the discussions in the Delphi rounds extended beyond these specific inquiries. A total of 7 h were spent during the discussions of the two Delphi rounds. The remainder of the Delphi method consisted of the activities listed below:
-
1.
Establish a problem statement—The problem statement represents the general question that will be central to the topics discussed during the process. In our case, the problem statement is the following: How can a programme for maritime cyber security training be developed in a way that addresses the limitations of current offerings?
-
2.
Appointing a facilitator/s—The facilitator had the responsibility and was in charge of the following activities: coordinating each round of the Delphi method, analysing the results of the rounds disseminating a report of the results of each round of Delphi to the participants, summarizing the final results and disseminating the final report and programme to the participants. Two facilitators were chosen. One was in charge of moderating the discussion during the Delphi, while the other had note-taking duties. Both facilitators were in charge of analysing the data collected during the Delphi rounds, to complete reports for each round.
-
3.
First round of Delphi—A first round was conducted with four academics working on maritime cyber security, focused on collecting feedback on current maritime cyber security training, as well as initial feedback on the MarCy programme. The round also served as an evaluation of the format of discussion to be used during the next Delphi discussions. The first round took around two hours to complete.
-
4.
Second round of Delphi—One more round was scheduled with additional experts from both industry and academia. Due to the number of participants, the round was split into two sessions on different dates. 13 participants joined the first session, while 10 the second session. Participants joined the sessions based on their availability, with a majority of participants joining one of two sessions, while a minority joined both sessions. 17 unique participants attended in total, between the two sessions. Both sessions focused on current maritime cyber security training and feedback on the MarCy programme, although each focused on a different set of questions on each of the topics. In total, the two sessions took over five hours to complete.
-
5.
Questionnaire—After completing the two rounds of the Delphi, a questionnaire was sent to selected participants who were not available during the previous rounds. The questionnaire summarized all the topics discussed during the previous rounds of Delphi. Together with the questionnaire, a report summarizing the results of the previous Delphi discussion was sent to participants. Despite our endeavour, we were not able to receive any input through the questionnaire for our study.
-
6.
Conclusion of the Delphi method—After collecting feedback from all participants, a final report summarizing all the inputs and conclusions reached by participants was completed. The report was shared with all participants for validation and recommended changes and considerations were later integrated into the programme.
Each round of Delphi was conducted digitally, via an online video-conferencing tool. A video and written transcript of each meeting were recorded. No information regarding participants’ identities or companies was disclosed in the reports. The rounds were all structured in two parts, one focused on collecting feedback on current maritime cyber security training offerings and their limitations, and the second part focused on feedback on the proposed programme. An initial broad discussion on maritime cyber security training was conducted to allow participants to discuss the State-of-the-Art (SoA) on maritime cyber security training, highlight current limitations, as well as recommend solutions to these limitations. Table 4 provides a description of the content of each of these parts.
5 MarCy: maritime cyber security training programme
In this section, we discuss in detail the MarCy programme for maritime cyber security training. The discussion is structured in sections, each focusing on a specific step. Here, we elaborate on the process by providing an example application field: the training of seafarers onboard and office staff in companies.
5.1 Identify the needs of the organization
The objectives of this step are to identify the nature of the problem [93]. In the first step, the training needs of the company should be identified, such as international regulations and class notations. Determined training needs identify the required training modules. Module codes and titles should be also specified in this step.
A company may need to train seafarers employed and office employees to improve their cyber awareness because of potential and occurred cyber incidents in the industry, cyber threats in threat landscape reports, and revealed cyber risks in studies. Furthermore, vetting, flag state, and class society requirements or recommendations may force companies to improve the cyber awareness of professionals employed.
The vetting programmes play an important role in the business life of a shipping company. The SIRE and CDI inspections force tanker management companies to provide sufficient training for seafarers employed to improve cyber awareness [106]. The TMSA requests tanker management companies to promote cyber awareness of ship and office personnel [102]. The RightShip recommends dry bulk management companies train seafarers and improve cyber awareness [115]. The next regime of the SIRE, SIRE 2.0, also will force tanker management companies to train seafarers employed for cyber security issues [101]. The SIRE 2.0 is expected to become operational in 2023.
The class societies, such as the ABS [15], Bureau Veritas (BV) [117], DNV [31], IRClass [63], Korean Register (KR) [26], Lloyd’s Register (LR) [118], and Nippon Kaiji Kyokai (ClassNK) [97], offer cyber security class notation for shipping companies. The expectation of class societies for the notation may include training of seafarers employed for cyber risks onboard ships (e.g. ABS [2], ClassNK [23], DNV [29], and IRClass [63]).
The Singapore Registry of Ships (SRS) provides voluntary notations for Singaporean ships, such as green, cyber, smart, and welfare notations [90]. Cyber notation is divided into three levels, including SRS Cyber Basic, SRS Cyber Intermediate, and SRS Cyber Advanced. The proof for the training of the crew is requested for any type of cyber notation [91]. Phishing attacks, suspicious e-mails, and insecure URLs shall be discussed in the training courses [91].
As per the ISM code requirements, each company must have a cyber risk management section in their SMS. This requirement has been verified in Document of Compliance (DOC) audits in the companies’ offices, and in Safety Management Certificate (SMC) audits onboard ships since 2 January 2021. Moreover, as per the IMO guide [50], the Ship Security Plan (SSP) should refer to such cyber risk management procedures in the SMS. Not only current regulations but also forthcoming regulations might need to be known to be ready. In December 2021, the Republic of Korea proposed to be discussed the necessity of developing inclusion for cyber security training for the STCW [51]. The Sub-committee on Human Element Training and Watchkeeping in the IMO was invited to discuss relevant provisions of cyber security-related training for seafarers [51]. As per the IMO, cyber security training is still not a requirement but would be a requirement or recommendation in the near future.
Companies may also need to train crew to be gained technical and procedural practice in the implementation. Moreover, the responsible person may require additional training for effective management of cyber security matters in the company. Last, advanced technical capability, such as the use of cyber security tools, could be required for some dedicated staff in a company.
The typical needs of a company are given in Table 5; however, companies might have additional training needs. In such a case, additional needs of the company should be specified as well as module code and title. Companies may not require all proposed training modules in Table 5. For instance, personnel of a company managing passenger ships don’t need to learn cyber security requirements in vetting programmes. Lastly, some modules may need to be specified by considering the company’s certain needs, including equipment onboard, class notations, flag state notations, vetting requirements, operating systems, installed software, company SMS, and so on.
5.2 Specify job performance
The objective of this step is to investigate employees’ roles and responsibilities [93]. We analysed seafarers onboard and employees on the shoreside of companies. To this end, we perused the SMS of three companies, the websites of several companies, flag state documents, the STCW Convention, the ISM Code, and the ISPS Code. Furthermore, we performed a literature review. Afterwards, gathering data was synthesized and organized.
Each company may have a different organizational schema and identify different responsibilities for each role. Ships are managed as per national and international requirements. Thus, designing an organization chart and identifying roles for the crew onboard are easier. However, various variations for the organization and responsibilities are existing in the office side. In Sects. 5.2.1 and 5.2.2, a generic viewpoint for crew and shore staff is provided to understand roles and responsibilities. Moreover, the CySO role for ship and office is explained in Sect. 5.2.3.
5.2.1 Seafarers on a typical ship
The crew of a ship can be divided into three categories: master, officers, and ratings. The IMO defines master as “the person having command of a ship” [60]. The IMO defines an officer as “a member of the crew, other than the master, designated as such by national law or regulations or, in the absence of such designation, by collective agreement or custom” [60]. The IMO defines a rating as “a member of the ship’s crew other than the master or an officer” [60].
A typical ship can be divided into three departments, including deck, engine, and catering (galley). The master is not involved in any departments. The deck department consists of deck officers and ratings. The deck officers are typically responsible for safe navigation, communication, and cargo operations onboard [126]. The deck officer states chief officer (C/O) (known as chief mate), second officer (2/O), \({3}^{\textrm{rd}}\) officer (3/O), deck cadet (D/C) (trainee deck officer). The deck rating depicts bosun (known as boatswain), able seaman (A/B), and ordinary seaman (O/S). The engine department consists of engineer officers, electro-technical officers, and ratings. Engineer officers are typically responsible for the maintenance and operation of the ship’s main propulsion and auxiliary systems [127]. The engineer officer state chief engineer (C/E), 2/E (known as first assistant engineer), third engineer (3/E) (known as second assistant engineer), fourth engineer (4/E) (known as third assistant engineer), and engine cadet (E/C) (trainee engineer officer). Electro-technical officers are responsible for monitoring, operation, maintenance, and repair of several systems onboard ship, such as electrical, electronic, and control systems [60]. Furthermore, electro-technical officers should be able to operate computers and computer networks on board ships as per the IMO requirements [60]. Many documents still call electrical officers. However, it was replaced with electro-technical officers as of STCW 2010 [84]. The engine rating denotes fitter (known as donkeyman), oiler (known as motorman), and electro-technical rating. The catering department consists of a cook and a steward. Last but not least, as per the ISPS Code requirement, an SSO must be designated on each ship [54]. The roles and responsibilities of the crew by rank are described comprehensively in [6, 12, 60, 77, 82, 112]. Master, C/O, C/E, and 2/E are at the management level and are called senior officers [77]. 2/O, 3/O, 3/E, and 4/E are at the operational level and are called junior officers [77]. The ratings are at the support level [77]. The crew number has decreased with the effect of technological developments in the maritime industry. Thus, the companies started not to man vessels with a steward, particularly vessels with up to nearly 20 crew members. Each vessel may have a different organizational structure. For instance, the master or C/O is nominated as an SSO in a typical cargo ship. However, a dedicated SSO might be nominated for passenger ships. Another example is gas engineers manned to gas carriers.
Figure 2 represents a typical ship organization chart for cargo ships. A vessel may be manned with more or fewer seafarers. The dark green colour denotes deck officers. The grey colour states deck ratings. The dark blue colour denotes an electro-technical officer and engineer officers. The orange represents engine ratings. The red colour represents ratings in the catering department. The turquoise colour depicts the master. Master is also stated with four circles in the figure. Three circles represent leaders of deck and engine departments (i.e. C/O and C/E). Two circles state officers other than department leaders. A circle expresses ratings.
5.2.2 The departments and individual roles in a typical company
Many departments for a reliable operation serve in a company. Roles and responsibilities of departments and employees in a department are variable by company requirements and management decisions. In a typical company, the claims & insurance department follows and manages claims (e.g. cargo, bunker, charter party, and collision claims) and insurance process (e.g. Protection and Indemnity (P &I) and Hull and Machinery (H &M)) [138]. The IT department is responsible for the maintenance, monitoring, and installation of IT systems, including hardware and software (e.g. switches, routers, laptops, operating systems, and antivirus). The operation department provides voyage management and operational support, such as assigning surveyors for cargo and bunker surveys and arranging fresh water and bunker supply. The chartering department is responsible for the employment of the vessels [40]. The accounting department is responsible for all accounting tasks for each vessel and the company, including settlement of freight and charter accounts, payment of invoices, and settling of accounts for each crew member [121]. The financial department analyses shipping and capital markets, proposes investment ideas, and reviews the company’s financial statements [68]. The vetting department takes required actions both for internal and external audit and inspection requirements. The audit and inspection requirements are followed closely. The Health, Safety, Environment and Quality (HSEQ) department is responsible for the development and effective implementation of SMS as per the national (e.g. local laws) and international requirements (e.g. IMO requirements), vetting requirements (e.g. SIRE, CDI, RightShip, and TMSA), and standards (e.g. International Organization for Standardization (ISO)). The training department is responsible for the training of crew and office staff. The training programme is published, followed, implemented, monitored, and recorded by national and international requirements, vetting requirements, and findings in audits and inspections. The crewing department is responsible for the initial interview in the crew member and office employee selection. The vessels are adequately manned by the crewing department, considering national and international requirements. The technical department is responsible for the technical support, supervision, and audit of the vessels. The Planned Maintenance System (PMS) is developed and effectively implemented onboard ships. The technical department supports vessels in maintenance and repairs to minimize non-operational time by considering company procedures and national and international requirements. The purchasing department is responsible for the supply of spare parts, provisions, safety equipment, medicines, consumables, slop-chest articles, and so on. The marine department supports vessels with the loading, carriage and discharge of cargoes, and voyage planning [39].
Assigning a DPA is an ISM code requirement and is stated as “To ensure the safe operation of each ship and to provide a link between the company and those on board, every company, as appropriate, should designate a person or persons ashore having direct access to the highest level of management” [53]. As per the ISPS Code, a company must designate a Company Security Officer (CSO) at the office for ships who is responsible for monitoring security activities, improving security awareness, ensuring that Ship Security Assessment (SSA) is performed, and such [54]. Managers in the departments have strong leadership skills, capable of managing and motivating staff [39]. Superintendents have strong electronic, electrical, nautical, cargo, engineering, construction, and regulation knowledge based on the department in a company [39].
Figure 3 represents a typical organizational chart for a company. However, companies are allowed to design their organizational structure. Some services can be received from \({3}^{\textrm{rd}}\) parties. For instance, a commercial department is unnecessary if the commercial management is offered by an external provider. Each company may call employees in a department with different titles, such as director, manager, superintendent, coordinator, operator, auditor, officer, broker, assistant, accountant, and their variations (e.g. deputy, senior, junior). The DPA and CSO are only mandatory roles as per the IMO requirements as aforementioned.
5.2.3 Cyber security officer
Although it is not defined by the IMO, companies may nominate a CySO to their managed ships and/or to the office for the development, management, and implementation of the cyber security plans efficiently. The CySO is relatively a new notion for the maritime industry and may also be called an SCySO [63], Cyber security Representative [2], Ship Cyber Safety Officer [63], Chief Information Officer (CIO) [47], and CCySO [63] in different guidelines. In our study, we use the notions of SCySO and CCySO. CySO depicts both SCySO and CCySO in our study. ABS suggests electro-technical officers and chief engineers to be nominated as the SCySO [2]. We noticed that one of the deck officers is typically assigned as SCySO onboard. On the other hand, IT managers or DPAs are generally assigned as CCySO at the shoreside.
5.2.4 Identification of the responsibilities, ranks, and positions
As aforementioned, in this step, a company should identify the ranks, positions, and responsibilities of the crew and office personnel employed. Tables 6 and 7 represent typical responsibilities for crew and office staff. Such responsibilities were identified by considering Sects. 5.2.1, 5.2.2, and 5.2.3. In this step, the ranks for crew and positions for office staff should also be specified. For instance, a training superintendent may be responsible for training activities in a company.
Some roles (e.g. engineer officers in Table 7) and responsibilities (e.g. marine operations in Table 6) can be grouped if the individuals in such groups have the same training needs for cyber security. For instance, the engineer officers, including C/E, 2/E, and 3/E, could be accepted as a group. Since such ranks work on the same machinery systems onboard. That’s why they would have the same training needs for cyber security.
Employees whose responsibilities are not described in Tables 6 and 7, might work onboard or in the office. In such a case, responsibilities for the crew and office staff should be added to the tables and roles should be specified. Lastly, various training modules are shown in Tables 6 and 7. The function of such columns, including training modules, is elaborated in the next step (Sect. 5.3).
5.3 Identify learner needs
The objective of this step is to understand the specific learning needs of roles [93]. The training modules for each specific role are determined in this phase. The training modules in Table 5 are mapped with responsibilities as represented in Tables 6 and 7. The responsibilities of roles can be variable by company preference. That’s why modules should be mapped by considering responsibilities instead of roles. Given that responsibilities are already mapped with roles (in step 2 (Sect. 5.2)), the required training modules for each role are unveiled. Mapping modules with the responsibilities of employees could be complicated for some training designers. That’s why we also explained an easier way for module selection in Sect. 5.3.1.
After the required training modules are determined, an exam can be given to assess the knowledge of participants. If a participant has sufficient knowledge, it is unnecessary to give him/her such a training module. In this way, the participant doesn’t lose time and energy for the module he/she already knows.
5.3.1 The easier implementation for the module selection
In this section, an easier implementation in the module selection is explained for the training of seafarers and office staff. Firstly training needs of a company are determined by considering Table 5. Thus, the required modules are identified. Then, modules are placed as given in Table 8. In our example implementation, all training modules in the MarCy programme were determined as required. However, all of them might not be required for a company.
Secondly, the roles should be identified for crew and office staff. Typical responsibilities for crew and office staff are given in Tables 6 and 7. The roles should be specified by considering the responsibilities in the tables. As explained in Sect. 5.2.4, some individual roles can be grouped. In further paragraphs, you will find examples for such groups.
In our example implementation, the crew onboard consists of an individual role (i.e. SCySO) and five role groups (i.e. master and deck officers, engineer officers, electro-technical officers, other officers, and ratings). For instance, the master, C/O, 2/O, and 3/O were grouped as Master and Deck Officers in our example implementation. Such roles operate the same systems onboard such as navigation, communication, and cargo handling systems [126]. Engineer officers can operate the same systems, such as the main propulsion system and auxiliary systems [127]. The electro-technical officer is an individual rank and can operate electrical, electronic, and control systems, including computers and computer networks [60]. As aforementioned, each vessel may be manned with additional officers (e.g. gas engineer). Thus, we identified another role called other officers in our example implementation. Ratings as the last role was identified for our example. All individual roles and role groups are deployed in Table 8.
In the example, office staff consists of an individual role (i.e. CCySO) and four role groups (i.e. key staff, training staff, IT staff, and other staff). The key staff depicts employees who are responsible for the technical management of ships, such as DPA, CSO, managers (e.g. fleet and vetting managers), and superintendents (e.g. marine and HSEQ superintendents). Key staff also include the top management of the company, such as the Chief Executive Officer (CEO) and Chief Financial Officer (CFO). IT and training staff are other roles in our example implementation. The employees for operational support in other departments, such as accounting and purchasing departments are called other staff in our example implementation. All individual roles and role groups are placed in Table 8.
In the last step, training modules are mapped with roles. Tables 6 and 7 suggest training modules by responsibilities. By considering such suggestions, roles were mapped with training modules as represented in Table 8.
5.4 Determine objectives
The purpose of this step is to identify the specific objectives and learning outcomes for each training module [93]. In our study, each module includes a different objective as represented in Table 9. The learning outcome comprises three components to reach the objectives identified, such as knowledge, skill, and attitude [93]. Knowledge is defined as “the state of knowing about a particular fact or situation” [108]. Skill is defined as “the ability to do something well” [109]. Attitude is defined as “a feeling or opinion about something, especially when this shows in your behaviour” [17].
5.5 Build curriculum
The purpose of this step is to build a syllabus to meet the learning objectives stated in Table 9 [93]. The contents are specified by considering module objectives and desired learning outcomes (i.e. knowledge, skill, and attitude). The contents are divided into two groups: essential and helpful. Essential content is required to meet objectives [93]. Helpful content is supplementary to essential content [93]. We offered a content list for each training module as represented in Appendix 1. While designing the curriculum for modules, we perused current training courses, guidelines, questionnaires, and previous studies mentioned in Sect. 2.
The order of the modules and curriculum items is also decided in this phase [93]. Module 1: Basic Cyber Security is the required module to be taken before any other desired module. Other conditions are represented in Table 10. The sequence of the content in a module is given by considering the general to the specific approach.
5.5.1 Module 1: basic cyber security and Module 2: advanced cyber security
The objective of M1: Basic Cyber Security is to familiarize the crew and office staff with essential notions, cyber risks, and mitigation measures. However, Module 2: Advanced Cyber Security offers more details about cyber security. For instance, the term of malware is explained in the M1: Basic Cyber Security module. However, in the M2: Advanced Cyber Security module, types of malware, such as ransomware, key logger, and spyware are elaborated.
5.5.2 Module 3: regulatory requirements
The module is based on the IMO requirements and recommendations, including cyber security-related resolutions, codes, conventions, and audits. The IMO issued several circulars regarding cyber risks onboard ships. To understand such requirements and recommendations, firstly the related maritime notions should be known by participants. That’s why, firstly, related notions are explained in the module, such as ISM code, ISPS Code, DOC audit, SSP, SMS, and so on.
As mentioned in Sect. 5.1, an ISM Code regulation and ISPS Code recommendation are in place regarding cyber security. Such international requirements are explained to participants in this module. Flag state requirements and recommendations may be also involved. Based on the flag state of managed vessels, the circulars could be explained to participants. Potential deficiencies in audits and best practices can be shared with attendees. For instance, the combination of the Cyber Security Assessment with SSA could be an effective best practice for companies.
5.5.3 Module 4: vetting requirements
Tankers and dry cargo vessels might be subject to vetting requirements. Vetting programmes, such as SIRE, CDI, TMSA, and RightShip, are significant for the commercial life of a company. That’s why competitive companies struggle to fulfil vetting requirements, such as training, risk assessment, policy, and procedures.
The module comprises cyber security requirements in tanker and dry cargo vessel audits. SIRE, CDI, and TMSA are for tankers, but RightShip is for dry cargo vessels. A company operating only dry cargo vessels doesn’t need to be familiar with the requirements of tanker vetting programmes. Moreover, each tanker operator may not be subject to all types of tanker audits. For instance, a company operating petroleum tankers may not need to be familiar with CDI requirements. Because of these reasons, the module can be specifically designed by considering attendees’ learning needs.
5.5.4 Modules 5–6–7: critical deck, engine and other systems
The IMO divides the vulnerable systems onboard into eight categories, such as bridge systems, cargo handling and management systems, propulsion and machinery management and power control systems, access control systems, passenger servicing and management systems, passenger-facing public networks, administrative and crew welfare systems, and communication systems [56].
Although the IMO broke vulnerable systems onboard into eight categories, we investigated the cyber risks of such systems under three modules (i.e. Modules 5, 6, and 7) by considering the roles and responsibilities of the crew onboard. The master and deck officers are responsible for the operation of bridge systems, cargo handling and management systems, and communication systems. The engineer officers are responsible for propulsion and machinery management and power control systems. Module 7: Other Critical Systems was designed for the cyber risks of access control systems, passenger servicing and management systems, passenger-facing public networks, and administrative and crew welfare systems. Module 7 may need to be designed as ship specific. For instance, a cargo ship might not have a network for passengers.
5.5.5 Module 8: cyber security investments
Financial investments are crucial for cyber-secured systems. Investments are typically decided by management-level staff, such as the CEO, CFO, directors, or department leaders. This module is developed for key staff in a company to make an easier decision in cyber security investments. Moreover, the key staff is trained about optimum investment costs for cyber security. Investments are not only limited to costs of technical measures (e.g. antivirus license costs). For example, flag states and class societies started to offer cyber security notations for ships. The managers may be eager to make a contract with \({3}^{\textrm{rd}}\) parties for the protection, response, and recovery process. ISO 27001 information security management certification could be considered to be awarded. Last but not least, the key staff should be informed about Clause (CL) 380 in marine insurance policies (e.g. P &I and H &M) [25].
5.5.6 Module 9: cyber security practices
The module comprises hands-on training and may need to be designed company-specific. The attendee can learn the use of physical security tools (e.g. USB port lockers) and software security tools (e.g. antivirus and password management software). The update of the operating system and antivirus software are demonstrated. Furthermore, internet protocols onboard, such as Fleet Broadband (FBB), Very Small Aperture Terminal (VSAT), or mobile connections (e.g. 4 G and 5 G) are explained to make understand the cost and speed differences between connection types. Cyber security plans and procedures of the company can be explained to attendees. A risk assessment may be performed for potential cyber risks, as well. The attendee can learn how to be filled out the company documents, such as the checklist to follow in case of a cyber attack or the physical notebook to keep passwords. Last but not least, the attendee learns how to give effective training in this module.
5.5.7 Module 10: cyber security management
The module is designed for cyber security managers in companies. The participants learn to develop procedures, including protection, detection, response and recovery plans for cyber security. Participants will be also familiar with potential mutual points between maritime and cyber security, such as management of change procedures, internal audits onboard and office, ship-shore combined drills, and risk management. They learn the points that should be considered in alteration and new building projects. In this module, useful materials, including checklists, posters, guidelines, books, and such are introduced to participants, as well.
5.5.8 Module 11: advanced skills
In this module, the participants learn advanced cyber security tools, such as firewalls. They will learn system and network administration as well as penetration testing tools. Each vessel may have different risks. For instance, fishing and passenger ships don’t have the same risks. Passenger ships inherently have additional risks because of the complex IT network for passenger welfare systems. That’s why companies may assign a dedicated CySO to the office or vessel. Module 11 is designed particularly for dedicated cyber security staff.
5.6 Select instructional strategies
The objective of this step is to determine the appropriate instructional strategies for the curriculum identified [93]. Five instructional strategies are proposed for the modules identified, such as lecture, discussion, case study, drill, and demonstration. A module can be given with a strategy or a combination of multiple strategies.
A lecture is a one-way presentation from a speaker to participants [93]. Discussion is sharing ideas among participants about a specific topic [93]. Case studies, such as incidents, situations, stories, and scenarios are tools to develop critical thinking skills [93, 136]. A drill is a structured practice to strengthen previous learning [93]. The demonstration is a presentation and exercise about how to perform a procedure and use software or hardware [93].
The lectures in the MarCy programme can be given conventionally to learners. However modern training approaches can also be performed, such as adaptive learning [69] and flipped learning [34] techniques. The mentioned strategies, except the demonstration, can be given online, on-site (in the institutes, company offices, and seminar halls, etc.), and hybrid. The demonstration modality should be performed on-site. Hybrid training courses can be organized as multi-hub, as well. Given that the internet connection could be limited, video training courses should be also considered for ships. Drills are typically based on a structured scenario. The participants shouldn’t be aware of the scenario before the drill to understand their real reactions. A ship-shore combined drill may also be performed. Table 11 represents the potential instructional strategies for each module.
5.7 Obtain instructional resources
The objective of this step is to ensure that all required resources for the training are in place. In this section, we focus on physical and human resources, and training materials. [93]
Physical resources are regarding the facility, tools, and equipment. On-site training needs a physical environment, such as an air-conditioned classroom, blackboard, projector screen, projector, and computer could be required. If the online training is live, a camera, microphone, speaker (or headset), and light may be required, as well as their spares [107]. A reliable and broadband internet is necessary [107]. Alternative internet and electricity options should be provided because of the potential risks of disruptions [107]. Marine components and simulators depending on the design of the training can be used. Particularly Module 11: Advanced Skills needs various software and computers for the demonstration.
Lecturers should be selected studiously. Given that each module or content may require different expertise, each one can be given by a different expert. For instance, Module 4: Vetting requirements could be given by a lecturer with having maritime background. However, Module 11: Advanced Skills can be given more effectively by a lecturer coming from the cyber security field. The background of the lecturer solely is not sufficient to give such training. For instance, each professional in the maritime sector is not familiar with vetting programmes. On the other hand, professionals can be familiar with vetting programmes, but cannot be familiar with cyber security requirements in the vetting programmes. That’s why the experience and knowledge of the potential lecturers should be considered while hiring.
The training materials are books, scientific papers, guidelines, circulars, animations, videos, presentations, photos, and such. Several training materials have been published by credible organizations, as mentioned in Sect. 2.2. Moreover, the Republic of the Marshall Islands Maritime Administrator published a circular, including maritime cyber risk management resources [114]. Such documents can be used as training materials in the modules. In Appendix 1, potential training materials by modules, such as books, theses, scientific papers, guidelines, and questionnaires are represented, however, the resources are not only limited to them.
5.8 Conduct training
The objective of this step is to perform the training designed. Before the training, a schedule can be identified for relaxation. During this period, drinks and snacks can be provided. If a social event is organized one day before the training, limited alcohol can be served. However, if only a limited time exists before the training, soft drinks should be served to participants. For the food, the diets of the participants should be considered. For instance, some participants could be vegan or allergic. Attendees could be tired or busy with their tasks. Managers need a substitute in particular. Otherwise, they may not attend to training programme completely.[93]
The modules can be slightly modified by considering the attendees’ needs [93]. That’s why attendees’ needs should be understood before delivering each module or during the training. Correct training materials, more than the required number, should be ready for the participants [93]. The training can start with a short opening. If the training is recorded, the attendees should be notified in the opening. In an on-site training course, the participants should be informed about safety instructions in case of an emergency situation. Attendees should know the agenda and the objectives of the training and modules. Moreover, requirements for the completion of the training should be explained in the opening speech, such as a potential exam at the end of the training. The training schedule should be followed as far as possible. The training should be summarized in the conclusion. The last questions of the participants can be addressed.
The duration of the modules can be identified by considering the learning needs of the participants and the decisions of the responsible managers in a company. The contents of a module can be extended or narrowed by considering reserving time for the training. On the other hand, instructional strategies could be decreased or increased. For instance, a module can be given as only a lecture instead of a combination of lecture and case study to decrease the training period. The recommended training duration by modules is represented in Table 12. Such suggestions for the training period don’t include the required time for the examination. Some modules (e.g. Module 1: Basic Cyber Security) can be given onboard. In such a case, training may need to be short. The recommended training duration of Module 9: Cyber Security Practices and Module 10: Cyber Security Management are affected from the specialized curriculum, including software and procedural demonstration. Module 11: Advanced Skills depends on the participant’s background but would be a long-term module. Such training modules may need to be repeated at least once a year.
5.9 Evaluation and feedback
The evaluation phase is to examine the outcomes and objectives of the training designed. According to the recommendations provided in the CEM, training evaluation should occur two-fold: (1) continuous (formative) evaluation of training components developed should occur during the design of a training course and (2) summative assessment should occur at the conclusion of training [93].
The first type of evaluation would allow to analyse and revise each component developed of the training programme before conducting training. The main advantage of evaluating at this stage is ensuring that training is aligned with participants’ needs, as mentioned in [22]. Such form of evaluation and revision should occur throughout the life cycle of development, whenever key components are selected or developed in the previous steps of the programme. The main advantage of conducting continuous evaluation is that it helps in targeting precise components that may need revision instead of having to re-assess the whole training course.
Summative assessment or post-training tests, on the other hand, would allow for both evaluations of the performance of training participants post-training, as well as feedback collection. During the discussions conducted in the Delphi method used to evaluate the MarCy programme, participants suggested a number of qualitative and quantitative approaches to conduct this type of assessment, including using performance indicators and metrics, ranging from multiple-choice exams to log and system analysis for computer-based training. When it comes to qualitative evaluation, recommendations included discussion-based or survey-based feedback collection, observation and post-evaluation from external, senior personnel.
The data collected by the formative and summative assessments are critical for improving and revising the training offerings developed using the MarCy programme in successive iterations. Moreover, they can also provide a measure to improve the programme itself.
In addition to formative and summative evaluation, CEM recommendations include utilizing pre-tests. These tests should be administered before training is conducted and serve as knowledge and competence pre-assessment of the participants.
6 Evaluation of the programme
As previously discussed in Sect. 4, the evaluation of the MarCy programme was conducted using the Delphi method across two rounds. In both rounds, participants engaged in discussions concerning various aspects of maritime cyber security training and provided feedback on the MarCy programme. A comprehensive summary of the outcomes from the discussions during each round of the Delphi process is presented in the subsequent sections.
6.1 Main considerations that distinguish maritime cyber security training from other cyber security disciplines
In the context of maritime cyber security training, the unique operating environment of the maritime industry presents distinctive challenges compared to other sectors. Vessels face a range of complexities that demand specialized training approaches. One notable consideration is the potential difficulty in responding to a cyber attack promptly. Unlike land-based organizations, accessing a vessel for immediate response by a cyber security expert may prove challenging due to its remote location and limited connectivity to the internet. Moreover, the dynamic nature of maritime operations adds another layer of complexity. During a cyber attack, a vessel may be sailing, and the consequences of an attack, especially those affecting critical navigation systems, could lead to marine incidents such as collisions. Therefore, seafarers should be trained to recognize and respond to cyber threats. Furthermore, training programmes should be designed by considering the unique systems onboard, vetting and regulatory compliance, and the various roles and responsibilities of crew members.
6.2 Recommended training methods for maritime cyber security
Participants have given various recommendations, ranging from simulation-based approaches to classroom training. The main advantage of simulation-based training is allowing for hands-on training based on realistic scenarios, without causing security risks to vessels. A downside mentioned of simulation-based training was relative to implementation costs. To solve this issue, Virtual Reality (VR) based simulation training was recommended to be further developed. Classroom training was instead recommended due to a preference for face-to-face training. This was highlighted as many of the current Computer-based Training (CBT) solutions were seen to be ineffective at engaging participants. Overall, it was recommended to combine simulation-based and classroom-based training when possible, and keep a focus on real-life scenarios.
6.3 Limitations of current offerings in maritime cyber security training
Several limitations were highlighted by participants regarding current maritime cyber security training. These included lack of IT background of seafarers, limited material available for maritime cyber security training, lack of resources (e.g. time, fatigue, and onboard broadband internet) to conduct onboard training, lack of the IMO requirements for maritime cyber security training and of qualified trainers, budget limitations, heterogeneous systems between different vessels, lack of targeted training, need for language considerations in training provision, lack of motivation to pursue higher cyber security competences, and finally lack of cyber-threat intelligence sharing.
6.4 Solutions to current limitations
To resolve the limitations previously mentioned, participants suggested several measures, including; focusing on real-life case studies and scenarios to engage participants; updating training regularly; mandating training to new employees and ensuring it is repeated or continued for existing employees; adapting training to different languages; adding maritime cyber security training to formal education of cadets, encourage information sharing between different companies; promoting maritime cyber security training and cyber security culture using a top-down approach, with senior management championing these; use a bottom-up approach to ensure that all training elements are tied to relevant cyber security components; lecturers’ expertise should be considered other than their academic titles or the companies/institutes they work for.
6.5 Methods & criteria for evaluating maritime cyber security training
Evaluation of training was noted to be often less prioritized or sidestepped. This has been considered a key challenge in maritime cyber security training, as it limits training effectiveness and improvement. Recommended methods from participants consisted of a combination of qualitative and quantitative approaches. When it comes to quantitative approaches, participants suggested using performance indicators and metrics, ranging from multiple-choice exams to log and system analysis, in the case of CBT and simulation training. When it comes to qualitative evaluation, recommendations included discussion-based or survey-based feedback collection, observation and post-evaluation from external, senior personnel. Overall, it was agreed that evaluation should be defined based on the type and content of the training.
6.6 Additional considerations/comments
Participants followed the discussion with personal considerations about additional recommendations and considerations for maritime cyber security training. One consideration was introducing a new role: a dedicated CySO for either onboard (i.e. SCySO) or off-board duty (i.e. CCySO). This would be particularly valuable for larger size companies. Another point of discussion raised by participants focused on the real-life effectiveness of training. As cyber security training is becoming more commonplace and standardized, there is often an assumption that a company is sufficiently secure once training is completed. This may not reflect the actual state of preparedness of employees, as certifications obtained post-training often do not guarantee proper cyber security.
6.7 Feedback on the MarCy programme
When it comes to the evaluation of the MarCy programme, the majority of the participants found it to be well-structured and comprehensive. That being said, a number of recommendations for improvements were reflected to the programme. Table 13 summarizes all recommendations made during the multiple rounds of Delphi.
7 Discussion
The MarCy programme is an effective tool for instructional designers in designing maritime cyber security training programmes. The recommendations were developed not solely based on the authors’ opinions but also with contributions from experts in the field. In other words, the MarCy is a programme agreed upon by multiple experts. To the best of our knowledge, this aspect is unique in the literature.
After designing the MarCy programme, we gathered expert opinions using the Delphi technique. The presence of authors working in maritime cyber security facilitated finding experts, allowing contributions from a diverse range of companies and institutions spanning from the USA to Singapore. Following the CEM approach would have required at least eight meetings, which, considering time zone differences, might have reduced participation. We observed that the Delphi method could be used to validate similar programmes like MarCy, especially in fields with limited experts for designing specialized training.
Although the MarCy programme has not been implemented in a real training session, real-world applications are in place in the literature. We also intend to organize training sessions with various learner groups in the maritime sector to evaluate all stages of the MarCy programme and present our findings in an additional study.
It would be beneficial to implement the MarCy programme by two distinct groups. One group consists of the authors who proposed the programme, while the other includes instructional designers beyond the authors who can also test the MarCy programme. These designers could come from diverse backgrounds, including maritime and cyber security. This approach would yield varied findings.
While the MarCy programme is customized for maritime purposes, its modular approach can be used to develop a wide range of training programmes. It is not limited to maritime contexts or cyber security training alone. It can also be applied to designing formal education beyond industry-specific training.
In our study, we defined the application domain as cyber security training for both office and maritime personnel in maritime companies. The existing modules will address the training needs of many maritime professionals, but additional modules might be necessary. For instance, individuals working in shore control centres during the remote operation of autonomous ships might require a module specific to autonomous vessels. Navy personnel might need training against cyber attacks targeting military systems like fire control systems on warships. Workers in container terminals might need to learn about specific cyber risks related to container tracking systems.
The curriculum in the MarCy programme is provided in broad strokes and not overly detailed. For example, naval ships may have components like War (W)-AIS and W-ECDIS developed for military purposes. Therefore, curriculum preparation needs to consider the participant profile.
We believe that the MarCy programme will significantly facilitate the design of cyber security training for maritime sector stakeholders. Nonetheless, we still consider expert involvement in designing training to be highly valuable. As mentioned in Sect. 5.7, the training should be ideally delivered by experts. Given the scarcity of experts in the maritime cyber security field, dividing the curriculum and having different experts teach based on their specialities could be beneficial.
As previously mentioned, maritime cyber security training is offered by various institutions and is documented in the literature. However, openly accessible curriculums are limited. The MarCy programme provides comprehensive curriculum suggestions for instructional designers. Even if a designer chooses not to use the MarCy programme, the provided curriculum can still be valuable.
While this study does not primarily aim to conduct a literature review on maritime cyber security training, it encompasses a thorough examination of existing training, recommendations from academic publications, considerations in vetting programmes and class notations. Thus, it provides a broad perspective to readers and guides researchers to areas requiring further investigation. Furthermore, readers unfamiliar with the maritime sector gain basic insights into the organizational structure and responsibilities within ships and offices.
Through this work, we extend the CEM and contribute scientifically to the literature while facilitating the design of maritime cyber security training for industry experts. In other words, we believe that our study not only holds scientific value but also addresses the practical needs of the maritime sector.
8 Conclusions
In conclusion, the mounting concern surrounding cyber risks within the maritime industry has necessitated a call for swift, proactive measures. The potential fallout from a successful cyber attack—including economic losses, data breaches, and compromised operational safety—underscores the utmost importance of cyber awareness. Training emerges as an indispensable tool to heighten cyber awareness and subsequently shield against these threats. This need has garnered support, finding its place within vetting programmes, cyber notations of class societies and flag states, and even proposed integration within the STCW for seafarers.
The distinct responsibilities and roles held by employees necessitate customized training methodologies. In response, we proposed the MarCy training programme by implementing the CEM to address the unique demands of professionals in maritime cyber security training. This transformation commenced by distilling a modular training programme from the CEM. Due to the scarcity of maritime cyber security experts on a global scale and the CEM’s mandate for a minimum of eight meetings with experts, the evaluation phase underwent meticulous adjustments. Last, all stages are customized for maritime cyber security training. The MarCy training programme, born from the tenets of the CEM, encompasses a meticulous nine-stage process:
-
1.
identify the needs of the organization;
-
2.
specify job performance;
-
3.
identify learner needs;
-
4.
determine objectives;
-
5.
build curriculum;
-
6.
select instructional strategies;
-
7.
obtain instructional resources;
-
8.
conduct training;
-
9.
evaluation and feedback.
By implementing the MarCy programme, we have defined eleven elective training modules specifically designed to enhance the knowledge, skills, and attitudes of seafarers and office personnel in safeguarding against maritime cyber risks. Additionally, the programme’s flexibility enables it to be tailored to meet the diverse needs of various stakeholders within the maritime domain. The training modules proposed in this study include:
-
M1: Basic cyber security;
-
M2: Advanced cyber security;
-
M3: Regulatory requirements;
-
M4: Vetting requirements;
-
M5: Critical deck systems;
-
M6: Critical engine systems;
-
M7: Other critical systems;
-
M8: Cyber security investments;
-
M9: Cyber security practices;
-
M10: Cyber security management;
-
M11: Advanced skills.
The carefully selected modules were aligned with the potential responsibilities within a company’s organizational structure. Onboard positions like Master and Chief Engineer, as well as office roles such as CEO, CFO, DPA, and more, were thoroughly considered. Subsequently, we outlined the objectives and curriculum for each training module. Instructional strategies, such as lectures, discussions, case studies, drills, and demonstrations, were carefully recommended for each module. Additionally, we paid close attention to the required physical and human resources, as well as the necessary training materials. Finally, we delved into determining the optimal duration for each module, while also addressing key considerations for the training sessions.
The robustness of the MarCy programme was subsequently confirmed through a Delphi technique involving 19 experts from both academic and industrial backgrounds, resulting in refinements based on their insights. During the Delphi rounds, discussions also revolved around the multifaceted dimensions of maritime cyber security training. Novel strategies, such as VR-based simulations were proposed as innovative instructional solutions. Furthermore, the vital role of comprehensive evaluation methods for learners, encompassing both qualitative and quantitative dimensions, was strongly emphasized. Given the limited availability of publicly accessible information on past cyber incidents, it was noted that stakeholders should be encouraged to provide detailed information about occurred incidents. To enhance effective countermeasures, the proposal was made to assign dedicated cyber security roles, especially within larger shipping companies.
The potential of the MarCy programme is not confined to its current scope. It boasts the adaptability to embrace additional modules, catering to a diverse array of learner groups and scenarios. From professionals in port facilities to those in the shore control centres of autonomous vessels, and even within governmental entities like maritime administrations and naval forces, the programme’s application is far-reaching. Furthermore, it extends its utility to crafting formal education courses. Our forthcoming endeavours are geared towards the deployment of this programme across diverse learner groups within the maritime domain, fostering a well-informed and resilient maritime cyber security community.
