An expert system for preventing and auditing intrusion

Network security research is an important aspect of CSCW (computer supported cooperative work). It helps to make work environment essential and reliable. Access control security technology mainly includes firewall technology, intrusion detection technology, and security auditing technology. These technologies still have some problems and shortages though they are matured in some degree. The expert system for preventing and auditing intrusion is a series of software and hardware systems for reducing the risk of computer network security. It is an effective closed loop control system that integrates with firewall, intrusion detection, and auditing trail analysis. It uses the learning ability of expert system to add knowledge and rules. Also it combines the characteristics of real-time and unreal-time to form an access control security system and enhance the security of the network.
