Security Analysis of Interaction between RBAC Model and Distributed Administrative Model
Безопасность информационных технологий, 2011 This paper proposes a formal approach to security analysis of a RBAC model which specification contains a model of distributed administration for user role assignment. A high-level description of security verification algorithm is provided.

Implementation of Formal Semantics and the Potential of Non-Classical Logic Systems for the Enhancement of Access Control Models: A Literature Review [PDF]
arXiv, 2023 This literature review discovers an implementation of formal logic systems in cyber security by enhancing access control models. We explore the characteristics of the existing access control theories, their limitations and how classical logic is used therein.

RelBAC: Relation Based Access Control [PDF]
, 2008 TheWeb 2.0, GRID applications and, more recently, semantic desktop applications are bringing the Web to a situation where more and more data and metadata are shared and made available to large user groups. In this context, metadata may be tags or complex

An Insider Threat Mitigation Framework Using Attribute Based Access Control [PDF]
arXiv, 2023 Insider Threat is a significant and potentially dangerous security issue in corporate settings. It is difficult to mitigate because, unlike external threats, insiders have knowledge of an organization's access policies, access hierarchy, access protocols, and access scheduling.

Towards A Generic Formal Framework for Access Control Systems [PDF]
arXiv, 2012 There have been many proposals for access control models and authorization policy languages, which are used to inform the design of access control systems. Most, if not all, of these proposals impose restrictions on the implementation of access control systems, thereby limiting the type of authorization requests that can be processed or the structure ...

Zero Trust Federation: Sharing Context under User Control toward Zero Trust in Identity Federation [PDF]
arXiv, 2022 To securely control access to systems, the concept of Zero Trust has been proposed. Access Control based on Zero Trust concept removes implicit trust and instead focuses on evaluating trustworthiness at every access request by using contexts. Contexts are information about the entity making an access request like the user and the device status ...
