Research on the Platform of Linkage between Intrusion Detection System and Firewall

The advantages of intrusion detection system and firewall technology are analyzed.It is very important of implementing complementary between data filtering of firewall and real-time monitoring of intrusion detection system.The basic classification method of the network security event is proposed,and the information format which intrusion detection system provides to the firewall is defined.By embedding the relevant modules in the intrusion detection system and firewall,the intrusion detection system could automatically respond to aggressive behavior,and firewall and intrusion detection systems could work together.So whether attacks are from the internal network or external network,they could be recognized and be responded automatically.
