Capability driven vulnerability analysis of a naval combatant

This paper presents a fine-tuned approach to vulnerability assessment, focusing on protecting capabilities instead of individual systems and their components. The foundation of this method is a system model which uses functional chains to identify the contribution of individual systems towards to fulfilment of the ships capabilities. The key advantage of using functional chains is that by showing that individual functions can still be fulfilled, it is demonstrated that the vital capability containing those functions remains available. This paper first explains the theory behind the methodology and then demonstrates its working principles using a generalized case study for a single capability.
