Pattern Matching Algorithm Based on Distributed Intrusion Detection System

The basic concept,history and development trend of intrusion detection are expound in detail,and all kinds of detection methods are studied,then a new intrusion detection algorithm based on Boye Moore algorithm is proposed to realize pattern matching which is the key part in intrusion detection.The new algorithm can improve the detection speed of engine.The experiments show that the technology can greatly improve the efficiency and stability of the system,and meet the requirements of design.
