Assurance cases, as a generalisation of safety case to security and dependability, are a powerful approach to justifying and communicating the trustworthiness of a complex system.  We have defined an assurance case as: "a documented body of evidence that provides a convincing and valid argument that a system is adequately dependable for a given application in a given environment". Assurance cases are based on the key concept of claims, arguments and evidence. There is a need for methods to define and structure claims (e.g. that the security properties are satisfied, that hazards have been mitigated, that vulnerabilities have been addressed, and that business continuity is being supported), and show how these are discharged with compelling arguments commensurate with the criticality of the system being assessed, while providing supporting evidence (such as from testing, analysis). Assurance cases are often embedded within a safety and security management process and often within a regulatory or licensing process that provides for independent challenge and review. Assurance cases can play a pivotal role in audits and reviews, as well as in incident management and investigation, where they can play a role in on-going processes, as well as use evidence from previous incident occurrences in the context of new assurance cases. It is important to understand the range of standards that can be applied and their role and limitations.
