Network Simulation and Vulnerability Assessment Tool for an Enterprise Network

The system proposed in this paper is the development of a methodology for a Network Vulnerability Assessment (NVA) tool capable of scanning and reporting vulnerabilities over the intranet and network simulator for enterprise networks which is capable of analyzing network behavior using enhanced GNS3. The proposed NVA tool implements network function in a controller which has the potential to extend vulnerability scanning for any devices. We had tested the system using a test bed with the features like scanning various vulnerabilities based on the type of networking device from the controller/vulnerability scanner in the same network. We have automated telnet/SSH connection using python script, which can help in automation and integrate network programming features from a controller. This version of the tool can be used to identify the possible vulnerabilities in any enterprise network and the methodology can be extended to incorporate better-secured networks.
