Overview
IP-based multimedia communications have become increasingly popular in recent years. With the increasing coverage of the IEEE 802:11TM based wireless\xa0networks, IP-based multimedia communications over wireless networks are also drawing\xa0extensive attention in both academia and industry. Due to the openness\xa0and distributed nature of the protocols involved, such as the session initiation protocol\xa0(SIP) and the IEEE 802:11TM standard, it becomes easy for malicious users in\xa0the network to achieve their own gain or disrupt the service by deviating from the\xa0normal protocol behaviors.\xa0This SpringerBrief presents real-time intrusion detection techniques that can quickly track the malicious behaviors which manipulate the vulnerabilities from either the 802.11TM or the SIP protocols. More specifically, this book presents interdisciplinary techniques to achieve an effective real-time intrusion detection system, which interweaves medium access control (MAC) protocol analysis, cumulative sum (CUSUM) based detector design, a novel Markovian model for CUSUM detectors, sketch-based traffic modeling, and wavelet based signal processing techniques.
