Intrusion Detection Networks: A Key to Collaborative Security supplies a complete introduction to intrusion detection systems (IDS) and intrusion detection networks (IDN). Describing how to leverage effective and efficient collaboration between participant IDSs, it explains the benefits of building IDNs, identifies the challenges underlying their design, and outlines possible solutions. It also reviews the full-range of proposed IDN solutions-analyzing their scope, topology, strengths, weaknesses, and limitations. It also includes a case study that illustrates the application of collaborative intrusion detection to real-world malware detection scenarios.
