Survivability analysis for information systems

Abstract

Information system plays an important role in modern society, and its performance of survivability is a vital attribute for people. Based on the relation between the system and environment, the survivability analysis model is divided into three models: environment, system and analysis model. Then, survivability is computed through resistance, recognition and recovery under each environment and the system should stand by a hierarchical analysis process. Finally, the general analysis method is given to describe the entire process of analyzing the survivability of the information system. The three models and quantitative analysis method is practicable if the parameters involved are measurable and modularized
