Network Security Control And Audit Expert Systems

With the rapid development of network technologies, the network security problem becomes more and more important. Also the researches on network security theory and protection techniques need creation and improvement continually. At present there are many kinds of network security techniques,and among which firewall technique and intrusion detection technique and security technique are applied most wildly. However, the three kinds of technique has some disadvantages in single use. Therefore, making synthetically use of the three kinds of technique to build an intrusion protection system become an important problem in the network security field.Based on the background requirement, this thesis researches the interaction of firewall and intrusion detection system (IDS) and security audit technique thoroughly. Firstly, this thesis introduces the development background of the network security techniques and research status at home and abroad. Secondly, it mainly discussed the ways of interacting between firewall technique, intrusion detection technique and security audit technique. Aimed at the futures development prospect of the network security techniques, build a network security and defense system named intrusion control and audit expert system on basis of the interaction mode of firewall and IDS and security audit. Thirdly, the system framework and concrete solution of intrusion control and audit expert system is put forward . It also designs the constitution module in the system in detail.
