Assessment of Network Security Policy Based on Security Capability

The validity of the security policy has important impacts on the safety performance of network information system. For purpose of verifying it effectively, an assessment model of network security policy based on security capability is proposed. The relationship of defense methods, application targets, and information security attribute characteristics is analyzed based on the establishing of security domain and security policy, and the network security capability of security policy is evaluated. Result shows that the model can effectively reflect the protect ability of security policy. It provides a new solution and reference for assessing and adjusting the network security policy, so as to better ensure system security.
