Probabilistic risk assessment provides a practical approach for assessing the security capabilities of systems. Terrorism risk assessment requires estimation of the probabilities and consequences of hypothetical attacks against a target. In order to address the interdependencies between the different elements present in the target environment we propose to develop a computer-based model. The model...
We describe a benchmark of publicly-available multi-threaded programs with documented bugs in them. This project was initiated a few years ago with the goal of helping research groups in the fields of concurrent testing and debugging to develop tools and algorithms that improve the quality of concurrent programs. We present a survey of usage of the benchmark, concluding that the benchmark had an impact...
The definition of an oracle function for model transformation is challenging because of the very complex nature of models resulting from a transformation. Validating the correctness of an output model requires checking a large number of properties on the structure and semantics of this model. The oracle function can thus be very complex if it checks every property. In this paper, we identify and discuss...
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:...
