摘要
入侵容忍技术是继防火墙、存取控制、入侵检测技术之后的网络信息安全技术。当一个网络系统遭受非法入侵后,入侵容忍系统仍能及时自我诊断、恢复和重构,并能为合法用户提供所需的全部或者降级的服务。本文依据非确定性有穷自动机理论,模拟计算机受到攻击时入侵容忍系统的工作过程,为入侵容忍技术的发展提供了一种方法。
Intrusion Tolerant is a new technique of security of information and networking after fire wall,access control, and intrusion detection. In the network environment,an intrusion tolerant system is capable of self- diagnosing, recovering reconstruction and continuing to provide service to legitimate clients in the presence of intrusions. Based on non - deterministic finite automaton machine describes the working method while the computer is attacked and provides a way to develop intrusion tolerant technique.
