In computer systems security, role-based access control (RBAC) [1][2] or role-based security[3] is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). Role-based access control is a policy-neutral access control mechanism defined around roles and ...
Rule-Based Access Control (RAC) RAC method, also referred to as Rule-Based Role-Based Access Control (RB-RBAC), is largely context based. Example of this would be allowing students to use labs only during a certain time of day; it is the combination of students' RBAC-based information system access control with the time-based lab access rules ...
Attribute-based access control. Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases ...
A Mandatory Access Control system implements a simple form of rule-based access control to determine whether access should be granted or denied by matching: An object's sensitivity label; A subject's sensitivity label; Lattice-based access control: These can be used for complex access control decisions involving multiple objects and/or subjects ...
Biba Model. The Biba Model or Biba Integrity Model developed by Kenneth J. Biba in 1975, [1] is a formal state transition system of computer security policy describing a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity. The model is designed so that subjects may not ...
NIST RBAC model. The NIST RBAC model is a standardized definition of role-based access control. Although originally developed by the National Institute of Standards and Technology, the standard was adopted and is copyrighted and distributed as INCITS 359-2004 by the International Committee for Information Technology Standards (INCITS).
Organisation-based access control. In computer security, organization-based access control ( OrBAC) is an access control model first presented in 2003. The current approaches of the access control rest on the three entities ( subject, action, object) to control the access the policy specifies that some subject has the permission to realize some ...
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
