摘要: Being a fast-growing Internet application, voice over protocol (VoIP) shares the network resources with regular traffic, and is susceptible to existing security holes of Internet. Moreover, given that communication time sensitive uses suite interacting protocols, VoIP exposes new forms vulnerabilities malicious attacks. In this paper, we propose highly-needed intrusion detection system. Our approach novel in that, it utilizes not only state machines protocols but also interaction among them for detection. This particularly suited protecting applications, which melange are involved provide IP telephony services. Based on tracking deviations from machines, our solution shows promising characteristics low runtime impact perceived quality streams
