1) HARD PROBLEM(S) ADDRESSED (with short descriptions)

• Composability through multiple semantic models (here, architectural, organizational, and behavioral), which provide separation of concerns, while supporting synergistic benefits through integrated analyses.
• Scalability to large complex distributed systems using architectural models.
• Resilient architectures through the use of adaptive models that can be used at run-time to predict, detect and repair security attacks.
• Predictive security metrics by adapting social network-based metrics to the problem of architecture-level anomaly detection.

3) KEY HIGHLIGHTS

We have generalized our simulator for insider anomalies to generate multiple anomalies in order to better evaluate our path-based anomaly detection algorithm.
