开放的复杂巨系统Internet可存活性需求分析框架

Survivability Requirements Analysis Framework for Internet as an Open Complex Giant System

传统的安全概念已不适应今天开放环境下的复杂信息系统。随着现代社会对Internet依赖性的增加,计算机网络系统的可存活性的需求成为亟待解决的问题。该文分析了Internet可存活性的重要性,提出了可存活性的需求框架,并使用HWMSE作为测试和评估网络系统可存活能力的方法,为提高巨型计算机网络的可存活性提供了有效的解决途径。

Traditional secure concept can not meet the needs of today's complex information system in the open environment. With the increase of the dependence of the modern society to Internet, the survivability requirement of the computer network system is becoming urgent. This paper analyzes the importance of the systems survivability and proposes a requirements framework of survivability. The methodology of HWMSE is introduced as a way to test and evaluate the survivability of network system. This paper provides an effective solution to improve the survivability of huge computer network.
