Security requirements are concerned with protecting assets of a system from harm. Implemented as code aspects to weave protection mechanisms into the system, security requirements need to be validated when changes are made to the programs during system evolution. However, it was not clear for developers whether existing validation procedures such as test cases are sufficient for security and when the implemented aspects need to adapt. In this chapter, we propose an approach for detecting any change to the satisfaction of security requirements in three steps: (1) identify the asset variables in the systems that are only accessed by a join-point method; (2) trace these asset variables to identify both control and data dependencies between the non-aspect and aspect functions; and (3) update the test cases ac-cording to implementation of these dependencies to strengthen the protection when a change happens. These steps are illustrated by a case study of a meeting scheduling system where security is a critical concern.
