Effect of Network Traffic on IPS Performance
The importance of network security has grown tremendously and Intrusion Prevention/Detection Systems (IPS/IDS) have been widely developed to insure the security of network against suspicious threat. Computer network intrusion detection and prevention system consist of collecting traffic data, analyzing them based on detection rules and generate alerts or dropping them if necessary. However, IPS has problems such as accuracy signature, the traffic volume, topology design, monitoring sensors. In this paper, the authors practically examine the traffic effect on performance of IPS.
