Web Services Security Using Semantic Technology

Abstract

For the present growing distributed Web Services (WS) communication, security is of significant concern in the context of dynamically changing entities. It is a challenge to ensure the security goals such as authentication, authorisation and policy bounded exchange that exists between dynamic web-based applications. As the WS are enhanced to next level Semantic Web Services (SWS), the syntactic based security approach are to be improvised using additional domain knowledge called semantics between the entities (web services). Therefore, the incorporation of semantics will upgrade the quality of security management and provide solutions to the security challenges. The service semantics extracted as additional knowledge describes the web services with which one can check the certainty of entity authentication. The appropriate use of the semantic in policy representation and evaluation against a request is more suitable for challengeable security management of present web information system. Overall, the chapter discusses the incorporation of semantics in all attempts of seeking security solutions that lead to enrichment of interoperability between web services in a dynamic instant.
