Case Study in Survivable Network System Analysis

This paper presents a method for analyzing the survivability of distributed network systems and an example of its application. Survivability is the capability of a system to fulfill its mission, in a timely manner, in the presence of attacks, failures, or accidents. Survivability requires capabilities for intrusion resistance, recognition, and recovery. The Survivable Network Analysis (SNA) method permits assessment of survivability strategies at the architecture level. Steps in the SNA method include system mission and architecture definition, essential capability definition, compromisable capability definition, and survivability analysis of architectural softspots that are both essential and compromisable. Intrusion scenarios play a key role in the method. SNA results are summarized in a Survivability Map which links recommended survivability strategies for resistance, recognition, and recovery to the system architecture and requirements. This case study summarizes the application a...
