A study from CA finds that 43% of IT execs deem SOA security as the most critical issue to their SOA implementation. Surveyed execs reported experiencing an average of seven XML targeted attacks against externally facing SOA or Web services applications in the past year. SOA security is very immature and have their own set of security issues such as replay attacks. Over half of the respondents have delayed a Web Service due to security concerns. Execs are also calling for SOA security to be integrated with identity and access management systems.
