In this paper, the authors propose a new and simple metrics for evaluating network security. The proposed metrics are based on the existence of network vulnerabilities in the network. The proposed metrics are different with their previous metrics proposed. 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, they 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.
