Security

An End-to-End Security Auditing Approach for Service Oriented Architectures

Free registration required

Executive Summary

Service-Oriented Architecture (SOA) is becoming a major paradigm for distributed application development in the recent explosion of Internet services and cloud computing. However, SOA introduces new security challenges not present in the single-hop client-server architectures due to the involvement of multiple service providers in a service request. The interactions of independent service domains in SOA could violate service policies or SLAs. In addition, users in SOA systems have no control on what happens in the chain of service invocations. Although the establishment of trust across all involved partners is required as a prerequisite to ensure secure interactions, still a new end-to-end security auditing mechanism is needed to verify the actual service invocations and its conformance to the expected service orchestration.
