【摘要】 随着计算机和计算机网络的应用普及,网络安全问题也日益突出,安全审计是网络安全体系中的重要一环,它在一定程度上弥补了防火墙和入侵检测的不足。介绍了一个安全审计系统的总体结构,对审计系统中收集到的一些信息进行分类后,重点讨论了如何对分类后的审计数据进行分析与处理,并在实际环境中进行了仿真测试。更多还原

【Abstract】 Network-based computer systems are playing increasingly important roles in modern society.Since they become the target of intrusions by potential intruders,network security is becoming a challenge.Because firewall and intrusion detection system cannot provide entire solution,network security audit system is becoming important parts in security solution.Therefore,the architecture of a security audit system is introduced at first,then all audit data are classified into three classes.Finally,data analyzingand processing methods are discussed with some experiments and some simmlations are conducted.更多还原
