Counter-intuitively, some traditional security requirements are not necessarily met by the game implementation some forms of security breaches are condoned by the stakeholders (if not actually demanded by them) and the requirements engineering process must support these contradictions...
We present a new approach for mutation analysis of security policies test cases. We propose a metamodel that provides a generic representation of security policies access control models and define a set of mutation operators at this generic level. We use Kermeta to build the metamodel and implement the mutation operators. We also illustrate our approach with two successful instantiation of this metamodel:...
Previous work in automating insider threat detection has included top-down analysis and fusion of events from network and system monitors. Situation-awareness can extend the capability of such techniques to include observables outside of cyber-space. The application of situation-management to insider threats is becoming more practical due to the growing volume of different types of transactions and...
