Abstract: IP telephony—also known as Voice over IP or VoIP—is becoming a key driver in the evolution of voice communications. VoIP technology is useful not only for phones but also as a broad application platform enabling voice interactions on devices such as PCs, mobile handhelds, and many other application devices where voice communication is an important feature. As the popularity of the VoIP systems increases, they are fast becoming a subject of a variety of intrusions. Some of these attacks are specific to VoIP systems, while others are general attacks on network traffic. In this paper, we propose an intrusion detection system framework for VoIP applications, called BLAZE. BLAZE has the capability to detect a variety of already known attacks, including Denial-of-Service attacks and media stream attacks and is novel enough to detect new attacks. It uses the mobile agent framework for collection and correlation of events among various network elements. The biggest advantage of using mobile agents in this framework is that we are not required to develop any new protocol for the intrusion detection support. Also, the functionality to perform the required recovery can be dynamically added to the mobile agents without changing the underlying VoIP protocols. We also present the concept of developing user profiles based on the user’s call behaviour. These profiles form the baseline against which any future behaviour of the user can be mapped to detect any new attack. (More)
