What is UR Activation Faults

Chapter 28
Handbook of Research on Information Security and Assurance
These faults can also be classified into two types: UA1—faults because of which an authorized user is restricted from activating a role or the activated role is improperly deactivated, UA2—faults by virtue of which an unauthorized user can activate a role. As noted previously, an authorized user can activate a role either by virtue of direct user assignment to that role or by being assigned to a role senior to the target role in A-hierarchy semantics. UA2 fault in an ACUT’ can result into serious compromise of confidentiality and integrity of the system resources because, in RBAC users are only able to access system resources through the mechanism of user-role activations.

Abstract
This chapter outlines the overall access control policy engineering framework in general and discusses the subject of validation of access control mechanisms in particular. Requirements of an access control policy language are introduced and their underlying organizational philosophy is discussed. Next, a number of access control models are discussed and a brief outline of various policy verification approaches is presented. A methodology for validation of access control implementations is presented along with two approaches for test suite generation, that is, complete FSM based and heuristics based. This chapter is aimed at providing an overview of the access control policy engineering activity and in-depth view of one approach to device test cases for an access control implementation mechanism.
