%0 Journal Article %T New Non Path Metrics for Evaluating Network Security Based on Vulnerability %A Tito Waluyo Purboyo %A Kuspriyanto %J International Journal of Computer Science Issues %D 2012 %I IJCSI Press %X 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. %K Network Security %K Metrics %K Network Evaluation %K Exploited Vulnerability %K Vulnerable Host %K Vulnerability Density %K IJCSI %U http://www.ijcsi.org/papers/IJCSI-9-4-1-487-492.pdf
