Architecture, models and techniques of functioning of the system of proactive monitoring of security policy

The paper considers issues applied to design and implementation of the system of proactive monitoring of security policy. The approach suggested is based on simulation of user actions in computer network under investigation. The generalized architecture of proactive monitoring system and its functioning techniques are described, problems applied to work in real network and their possible solutions are considered. The paper contains the description of prototype of proactive monitoring system and the example of the prototype using to test network security policy.
