Process-Aware Information Systems (PAIS) enable the automated support of business processes that are executed by a combination of human actors and systems. As processes typically require access to sensitive data, security policies are of high importance. Typically security policies in PAIS range from access rules and authorization constraints to context policies (location, time) and are scattered over the multitude of heterogeneous PAIS components, i.e. process models, repositories, organizational structures, etc. Currently, different approaches for modeling and enforcing security policies exist that assume a set of explicitly defined security policies.
