在信息高速发达的网络时代,网络中的信息安全越来越重要,而入侵检测系统以其独特的优势成为信息安全的主要防护手段。本文根据校园网安全现状,分析了入侵检测系统的结构及工作流程,重点安装、配置、调试了Snort程序,并将其部署到校园网网络中,经过观察检测,证明Snort既可以对外部入侵行为有效防范,又可以对内部用户非授权访问进行检测,能有效地实现校园网的安全防范。
In the era of high-speed information network, information security in the network is more and more important, and intrusion detection system with its unique advantages as the main means of information security. This paper analyzes the structure and workflow of intrusion detection system based on the status quo of campus network security, and focuses on installing, configuring and debugging the Snort program and deploying it to the campus network. After observation and testing, it is proved that Snort can not only detect external intrusion behavior Effective prevention, but also for unauthorized access to internal users to detect, can effectively achieve the campus network security.
