New Non Path Metrics for Evaluating Network Security Based on Vulnerability

In this paper, we propose a new and simple metrics for evaluating network security. The proposed metrics are based on the existence of network vulnerabilities a network. The proposed metrics are different with our previous metrics proposed in [11]. Exploited Vulnerability Percentage (EVP) metric, Vulnerable Host Percentage (VHP) metric and Density of Network Vulnerability (DNV) metric can be used to evaluate the security of a given network quickly because the calculation is not accompanied by path analysis. In the simulation section we provide a table of simulation results and two dimensional graphs in Cartesian coordinates. Analysis of simulation results and future works are also provided at the end part of this paper.
