Mutual exclusion of roles as a means of implementing separation of duty in role-based access control systems
Abstract
Role based access control (RBAC) is attracting increasing attention as a security mechanism for both commercial and many military systems. Much of RBAC is fundamentally different from multi-level security (MLS) systems, and the properties of RBAC systems have not been explored formally to the extent that MLS system properties have. This paper explores some aspects of mutual exclusion of roles as a means of implementing separation of duty policies, including a safety property for separation of duty; relationships between different types of exclusion rules; properties of mutual exclusion for roles; constraints on the role hierarchy introduced by mutual exclusion rules; and necessary and sufficient conditions for the safety property to hold. Results have implications for implementing separation of duty controls through mutual exclusion of roles, and for comparing mutual exclusion with other means of implementing separation of duty policies. 1 Introduction Role based access control (RBAC)...

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
