Index System of Information Systems Survivability: Formal Definitions and Reasoning

Establishment of quantitative and operable index system is the basis of quantitative evaluation for information systems survivability. This paper provides a complete overview on performance index for survivability from the aspects of index content, attack phases and evaluating standard, proposes a framework for performance index which can present the survivability, and formalizes the index system. On the basis of which, abstracts the mathematical model of index system, analyses and validates that the proposed index system has the features of standardization and completeness. This research is significant to quantitative evaluation for information systems survivability.
