An agent-based approach for policy enforcement in secure workflow systems

Modern business goals are often fulfilled with workflows that may cross many organisations and utilise services on a variety of devices and/or supported by different platforms. Current workflows are inherently context-aware. Each context is governed and constrained by its own policies and rules to prevent unauthorised participants from executing sensitive tasks and also to prevent tasks from accessing unauthorised services and/or data. We present a context-aware and secure workflow systems together with an efficient agent-based and sound approach for the enforcement of security policies.
