网络存储系统的可生存性研究

Study on Survivability of Network Storage System

可生存性是指当一个系统在遭受攻击、出现故障或发生紧急事件时,依然能够及时完成任务的能力。网络存储系统是信息系统的主要组成部分和支撑平台,对它的可生存性研究已成为研究的热点。从可生存性对于加强网络存储系统安全的意义出发,介绍了可生存性的定义、特性以及网络存储系统的可生存性分析框架。

Survivability is the capability of a system to fulfill its mission,in a timely manner, in the presence of attacks,failures, or accidents. Network storage system is the main part and sustainable platform of information system, and its survivability is a hot study point. This paper firstly proposes the study of survivability is important for the network storage system, it then introduces definition and characteristic of survivability, and a survivability analysis framework is also introduced. Finally, the possible further development directions are discussed.
