2. Access control matrix - Wikipedia

   en.wikipedia.org/wiki/Access_Control_Matrix

   According to the model, the protection state of a computer system can be abstracted as a set of objects , that is the set of entities that needs to be protected (e.g. processes, files, memory pages) and a set of subjects , that consists of all active entities (e.g. users, processes).

3. Access-control list - Wikipedia

   en.wikipedia.org/wiki/Access-control_list

   In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.

4. Computer access control - Wikipedia

   en.wikipedia.org/wiki/Computer_access_control

   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.

5. Protection mechanism - Wikipedia

   en.wikipedia.org/wiki/Protection_mechanism

   A simple definition of a security policy is "to set who may use what information in a computer system". [1] The access matrix model, first introduced in 1971, [2] is a generalized description of operating system protection mechanisms. [3] The separation of protection and security is a special case of the separation of mechanism and policy. [4]

   Security controls can also be classified according to the implementation of the control (sometimes termed control categories), for example: Physical controls - e.g. fences, doors, locks and fire extinguishers; Procedural or administrative controls - e.g. incident response processes, management oversight, security awareness and training;

9. Computer security model - Wikipedia

   en.wikipedia.org/wiki/Computer_security_model

   A computer security model is a scheme for specifying and enforcing security policies. A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy.
