Signaling message detecting method and system based on text coding

Abstract

The method includes steps: picking up and detecting bytes of signaling message to determine whether there is detected by test matched to diagnostic unusual characters in diagnostic unusual character base; if yes, then discarding the signaling message. The invention filters signaling message of containing unusual characters so as to prevent attack and destruction on server from hijacker, and guarantee normal operation of network service.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a text encoding-based signaling message detection method and system. Background technique [0002] With the rapid development of communication technology, the trend of network convergence is increasing, and the next generation network with the multimedia subsystem (IMS) as the core has arrived. While people are enjoying the flexible and convenient services brought by the next-generation network, the security of the next-generation network has become the focus of the industry. [0003] The security of the network border is the foundation of the entire network security. The next-generation network is a converged network that supports user access anytime and anywhere, so border security is particularly important. Since the next-generation network appears relatively late, there is no special next-generation network intrusion detection tool, especially for the dete...

Problems solved by technology

The detection of various attacks in IDS is based on its attack characteristics, but this detection method based only on characteristics is relatively simple and not flexible enough
