PY - 2010 DA - 2010// TI - Caching Strategies: An Empirical Evaluation BT - International Workshop on Security Measurements and Metrics (MetriSec) SP - 1 EP - 8 PB - ACM Press CY - New York, NY, USA AB - Modern enterprise systems comprise a fine-grained enforcement of complex access control policies. Consequently, the efficient evaluation of security policies is a significant factor for the overall system performance. Moreover, modern enterprise systems are inherently based on process and workflow models. These models enable new approaches for improving the performance of security evaluations. Caching is widely used for improving the performance and the reliability of systems. The dynamic nature of today’s workflow systems, both in terms of changing workflows and in terms of dynamic security policies impose particular challenges on the caching of access control decisions. We present a caching strategy that exploits business process models for avoiding cache misses. Moreover, we provide a detailed performance analysis of different caching strategies for static and dynamic aspects of access control policies, providing the required metrics for informed design decisions.
