An Activity-Based Model for Separation of Duty [PDF]

arXiv, 2008
This paper offers several contributions for separation of duty (SoD) administration in role-based access control (RBAC) systems. We first introduce a new formal framework, based on business perspective, where SoD constraints are analyzed introducing the activity concept.

Automated Validation of Security-sensitive Web Services specified in BPEL and RBAC (Extended Version) [PDF]

arXiv, 2010
We formalize automated analysis techniques for the validation of web services specified in BPEL and a RBAC variant tailored to BPEL. The idea is to use decidable fragments of first-order logic to describe the state space of a certain class of web services and then use state-of-the-art SMT solvers to handle their reachability problems.
