Role-based access control (RBAC) is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). RBAC is a policy-neutral access control mechanism defined around roles and privileges, and can be used to facilitate administration of security in large organizations.
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).
Access control is the selective restriction of access to a place or resource, based on authorization and credentials. Learn about physical and electronic access control, factors of authentication, and different types of credentials and systems.
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
Learn about ABAC, a method of implementing access control policies that is highly adaptable and can be customized using a wide range of attributes. ABAC is a next generation authorization model that is suitable for use in distributed or rapidly changing environments.
ReBAC is an authorization paradigm where permissions depend on relationships between subjects and resources. Learn about its history, implementations, and contrast with RBAC and ABAC.
Learn about the concept, implementation, and features of privileged access management (PAM), a type of identity management and cybersecurity that controls and protects privileged accounts. Find out the best practices, standards, and references for PAM.
The most common way of ensuring computer security is access control mechanisms provided by operating systems such as UNIX, Linux, Windows, Mac OS, etc. If the delegation is for very specific rights, also known as fine-grained, such as with Role-based access control (RBAC) delegation, then there is always a risk of under-delegation, i.e., the delegator does not delegate all the necessary ...
