Abstract

In this article, we present the design of an intrusion detection system for voice over IP (VoIP) networks. The first part of our work consists of a simple single- component intrusion detection system called. In the second part, we extend the design of and build a distributed and correlation-based intrusion detection system called Space Dive. We create several attack scenarios and evaluate the accuracy and efficiency of the system in the face of these attacks. To the best of our knowledge, this is the first comprehensive look at the problem of intrusion detection in VoIP systems. It includes treatment of the challenges faced due to the distributed nature of the system, the nature of the VoIP traffic, and the specific kinds of attacks at such systems.
