Security in software engineering requirement

摘要

A system can't have high assurance if it has poor security requirement, so for high assurance system will logically include security requirement as well as reliability, robustness security requirement is one of quality factors that systems try to satisfy which considered as another quality factor in a quality model. The close similarity between these two quality factors implies that a classification safety-related requirement is a good place to begin when developing an taxonomy of security-related requirements. The resulting taxonomy consists of pure security requirements specifying minimum acceptable amounts of security, security-significant requirements which are non-security requirements with important security ramifications, security system requirements specifying requirements for security architectural components, and security constraints.
