网络系统可生存性评估与增强技术研究概述

The Research Summarization of Technology of Network System Survivability Evaluation and Enhancement

网络系统可生存性是网络安全研究的新方向,它突破了传统的网络安全的概念,从新的角度对网络安全问题进行研究。本文首先对网络系统可生存性研究领域进行了总结,回顾了可生存性概念以及可生存系统的关键属性,论述了可生存性评估和增强技术之间的关系。然后,阐述了国内外可生存性评估模型以及可生存性增强技术的研究现状和技术方法,分析了不足之处,并提出可生存性评估技术与增强技术的结合,以及生存性进化等方面是未来发展方向。

As a new direction in network security,survivability is different from traditional network security,it gives a new way to research the network security. First, the research of survivability for network system is summarized and discussed in this paper. Survivability definition and Survivability key attributes are reviewed. The relationship of evaluation and enhancement technology is expounded. Second, this paper introduces survivability evaluation models and survivability enhancement methods at home and abroad, and then analyzes their defects, puts forward the cooperation of evaluation model and enhancement technology and survivability evolution are the orientation of survivability research.
