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
