The goal of security management is to control the access to sensitive information and resources based on security policies to prevent and defend against intentional or unintentional attacks in the network. Among the well-known network defending techniques stay the Intrusion Detection Systems (IDS). The IDS scans the incoming or outgoing network traffic in order to detect the malicious or suspicious activities. As networks become faster such that the High Speed Networks (HSN), there is a need for IDS to perform security analysis techniques that can keep up with the increased network throughput otherwise it becomes a network bottleneck. Efficient management of Distributed IDS (DIDS) is both a crucial requirement and a major challenge for security services.
