An Ontology Based Security Protection of SOAP Messages

Several Web Service security standards are widely utilized aiming at securing exchanges of SOAP messages among partners in a collaborative environment. Although such standards are suitable for ensuring end-to-end message level security, certain attacks such as XML rewriting may still occur and lead to significant security vulnerabilities. This paper explores the security vulnerabilities of SOAP messages and proposes an ontology-based approach that can successfully combat the security threats. We develop ontology-based schema to include SOAP structure information in outgoing SOAP message and validate this information in the receiving end. Thus, allow to detect XML rewriting attacks early in the validating process.
