摘要
Abstract
Through analysis of the network data packets about Session Initiation Protocol(SIP)-based Voice over Internet Protocol(VoIP) in the case of bypass monitoring, a method is proposed to recover the VoIP information on bypass monitoring. This method can deal with all kinds of complex situation, filter out the network data packets which have nothing to do with VoIP communications effectively and recover the behaviors and contents of VoIP communications correctly. This method implements a VoIP behavior analysis and content recovery system based on SNORT that is applied to practical projects.关键词
