入侵检测在防火墙系统中的应用

Application of intrusion detection in firewall system

该文针对防火墙无法防护内部网络用户的攻击以及不能防备新的网络安全问题的缺陷,提出把入侵检测与防火墙相结合来提供一个更加安全的防护措施,从而达到既可以检测到内部用户的异常行为,也可以检测出突破防火墙和系统限制后的非法入侵,并对其及时地进行处理。

In allusion to firewall’s defect： can not defend internal network users’ attack and can not prevent the new network security problem,this paper puts forward a more secure defending method,that is to make a combination of intrusion detection and firewall,which can not only detect the internal user’s abnormal action,but also detect the illegal intrusion pass by the firewall and the system’s restrict,and deal with it promptly.
