Abstract

New security threats arise frequently and impact on enterprise software security requirements. However, most existing security engineering approaches focus on capturing and enforcing security requirements at design time. Many do not address how a system should be adapted to cope with new unanticipated security requirements that arise at runtime. We describe a new approach - Model Driven Security Engineering at Runtime (MDSE@R) - enabling security engineers to dynamically specify and enforce system security requirements based on current needs. We introduce a new domain-specific visual language to model customer security requirements in a given application. Moreover, we introduce a new UML profile to help capturing system architectural characteristics along with security specifications mapped to system entities. Our MDSE@R toolset supports refinement and merger of these visual models and uses model-driven engineering to take the merged model and specify security controls to be enforced on the target system components. A combination of interceptors (via generated configurations) and injected code (using aspect-oriented programming) are used to integrate the specified security controls within the target system. We describe MDSE@R, give an example of using it in securing an ERP system, describe its implementation, and discuss an evaluation of applying MDSE@R on a set of open source applications.
