Abstract:

To approach a full assessment of network, a network security evaluation index system including 5 first grade indices and 18 second grade indices is established. With the multilevel extension assessment method, a novel network security evaluation approach is proposed. Analysis of example demonstrates that calculation result is really consistent with the realistic situation, the approach is able to reflect accurately the security status of network.
