An Observation Model to Detect Security Violations in Web Services Environment

Growing violation activity makes monitoring of information technology resource systems day by day necessity. As a matter of importance, the popularity of surveillance systems increases with its associated systems. The security of such surveillance systems plays a critical role as their compromise has a technical impact and the need for them is increasing. The complexity of surveillance systems is growing as the system architecture and application must fulfill various requirements of ever demanding project scenarios. The surveillance system is a tool that observes the service behaviour as the e-observer technique works. This paper is proposed an enhanced observer model which maintains a list of its dependents, and then automatically reports any changes in state to an evaluator model, by calling one of their methods. The e-observer is concerned with the state of service behaviour to determine whether it obeys, using its intended behaviour or policy rules; these policies are used to refer to the specific security rules for particular systems. However, web services have become more sophisticated in recent years. WSs are being used successfully for interoperable solutions across various networks.
