基于入侵检测技术的计算机网络安全研究

伴随着互联网技术的急速发展,海量的信息出现在网上,如何保护这些信息的安全,免受各种攻击就变得越来越重要.传统的网络安全技术主要是防火墙技术和加密技术,近年来出现了一种新的安全防护技术——入侵检测系统（Intrusion Detection System,简称IDS）.IDS的出现主要为防火墙进行必要的补充,二者的联动最大程度的保证了网络信息的安全,成为了网络安全的核心环节.

Based on the intrusion detection technology of computer network security research

along with the rapid development of Internet technology, huge amounts of information in Internet, how to protect the safety of the information, from various attack becomes more and more important.The traditional network security technology is primarily a firewall technology and encryption technology, in recent yearn, the appearance of a new security technology, Intrusion Detection System （ Intrusion Detection System, IDS ） .IDS appear to firewall to make the necessary supplement, the linkage of both maximum guarantee the safety of network information, has become a core part of network security.
