Access control is the set of mechanisms and policies used to restrict access to resources and enforce authorization decisions.

A mechanism that implements access control for a system resource by enumerating the identities of the system entities that are permitted to access the resources.

A table in which each row represents a subject, each column represents an object, and each entry is the set of access rights for that subject to that object.

Implementations of formal AC policy such as AC model. Access control mechanisms can be designed to adhere to the properties of the model by machine implementation using protocols, architecture, or formal languages such as program code.

Formal presentations of the security policies enforced by AC systems, and are useful for proving theoretical limitations of systems. AC models bridge the gap in abstraction between policy and mechanism.

an access control paradigm whereby access rights are granted to users through the use of policies which combine attributes together. The policies can use any type of attributes (user attributes, resource attributes, environment attribute etc.

A set of procedures and/or processes, normally automated, which allows access to a controlled area or to information to be controlled, in accordance with pre established policies and rules.

Access Management is the set of practices that enables only those permitted the ability to perform an action on a particular resource. The three most common Access Management services you encounter every day perhaps without realizing it are: Policy Administration, Authentication, and Authorization.

The official management decision given by a senior agency official to authorize operation of an information system and to explicitly accept the risk to agency operations (including mission, functions, image, or reputation), agency assets, or individuals, based on the implementation of an agreed upon set of security controls.

Routes that the BGP router will advertise, based on its local policy, to its peers.

Authentication is the process of verifying the identity of a user, device, or system before granting access.

Authorization is the process of determining what an authenticated principal is permitted to do.
