Training network managers in ethical hacking techniques to manage resource starvation attacks using GNS3 simulator

The threat of resource starvation attacks is one of the major problems for the e-Business. More recently these attacks became threats for Cloud environments and Denial of Service is a sub-category of these kinds of attack. The network management is process of taking proactive actions before the attack has taken effect which is responsibility of skilled employees - network managers. In recent time vulnerability testing skills are needed to harden system security. These skills have to be developed thus for we created scenario in a controlled environment, to provide opportunity for student trainees to train their skills, so that defense could be prepared. This paper describes a simulation-based training scenario using simulator and by using hacking tools in which student trainees experience the symptoms and effects of a DDoS attack, practice their responses in a simulated environment, with goal to prepare them for the real attacks.
