Although security plays a major role in the design of software systems, security requirements and policies are usually added to an already existing system, not created in conjunction with the product. As a result, there are often numerous problems with the overall design. In this paper, the authors discuss the relationship between software engineering, security engineering, and policy engineering and present a security policy life-cycle; an engineering methodology to policy development in high assurance computer systems. The model provides system security managers with a procedural engineering process to develop security policies.
