摘　　要：处于Internet中的重要信息系统面临的安全问题越来越多,如何增强系统生存能力,使系统在受到破坏后仍能继续提供用户需求的服务已引起人们普遍关注.笔者介绍了生存性定义,根据生存性具有的抵御、认识、恢复和演化4个功能属性设计了信息系统的生存体系结构模型,进而解释了模型中的系统生存需求、生存策略的含义.并依据生存策略的不同方面给出了为使系统达到生存性的技术措施.Critical information system in Interact is in face of increasingly security problems. More attention has been focused on the survivability of information system, which is the capability of system to continue its mission even in the presence of damage to the system. The authors first introduce the definition of survivability. According to four function properties of survivability, which are Resistance, Recognition, Recovery, and Adaption, the authors design a model of survivable system structure and then explain survivability requirement, survivability strategy in this model. Additionally, they provide possible technical solutions for the survivability of systems, categorized by different aspects of our survivability strategy.

关 键 词：生存体系结构 生存需求 生存策略 保护 检测和响应 恢复
