随着计算机网络技术的高速发展,利用广泛开放的网络环境进行全球通信已成为时代发展的趋势。网络在提供开放和共享资源的同时,也不可避免的存在着安全风险。曾经作为最主要的安全防范手段的防火墙,已经不能满足人们对网络安全的需求。文中简要地阐述了入侵检测系统的定义及其分类,详细地分析了目前入侵检测技术所面临的主要挑战并提出了未来入侵检测技术的发展趋势。
With the rapid development of computer network technology, the use of a wide range of open network environment for global communications has become the trend of the times. While providing open and shared resources, networks also inevitably have security risks. Once as the most important means of security firewall, can no longer meet people’s demand for network security. In this paper, the definition and classification of intrusion detection system are briefly described. The main challenges of intrusion detection technology are analyzed in detail and the future trend of intrusion detection technology is proposed.
