Research of NIDS in IPV6 Based on Protocol Analysis and Pattern Matching

Some network intrusion security problems of IPv6 are researched and summarized In this paper. And this paper introduces the model of general IDS and the framework of NIDS of Ipv6. Aiming at the structure characters of IPv6 protocols, a new research method of network intrusion detection system based on protocol analysis and multi-pattern matching is put forward. Protocol analysis technology can find protocol suspicious action quickly, and pattern matching technology can detect deep attack action by character matching. Finally, a detailed designing scheme and testing result are provided.
