A Hybrid Intrusion Detection System

For existing intrusion detection system using a single test mode is difficult to tackle the issue of omission and misstatement,this paper proposed a new SHIDS(Serial Hybrid Intrusion Detection System).We start from the open source software SNORT and then combines two different detect pattern together.The result shows that SHIDS has covers the shortage of single test mode while unknown viruses have also been pre-judgment:1) SHIDS has a lower omission rate and a faster detection speed 2) SHIDS has a lower misstatement rate and a higher explanatory.
