Policy-based computing is taking an increasing role in providing real-time decisions and governing the systematic interaction among distributed cloud and Web services. XACML has been known as the de facto standard widely used by many vendors for specifying access control and context-aware policies. Accordingly, the size and complexity of XACML policies are significantly growing to cope with the evolution...
By handling the orchestration, composition and interaction of Web services, the Business Process Execution Language (BPEL) has gained tremendous interest. However, such process-based language does not assure a secure environment for Web services composition. The key solution cannot be seen as a simple embed of security properties in the source code of the business logic since the dynamism of the BPEL...
In this paper, we introduce our approach for the automatic generation of BPEL (Business Process Execution Language) aspects from security policies. It is based on a synergy between policies, Aspect-Oriented Programming (AOP) and composition of web services. Our proposed approach allows first to transform security policies into BPEL aspects. Then, the generated aspects are weaved in the BPEL process...
In this paper, we address the problems related to the applicability and useability of security patterns. In this context, we propose a new approach based on aspect-oriented programming (AOP) for security patterns development, specification and deployment. Our approach allows the security experts to deliver their security patterns that describe the steps and actions required for security solutions,...
