Access control

In physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.

Access control on digital platforms is also termed admission control. The protection of external databases is essential to preserve digital security.^[1]

Access control is considered to be a significant aspect of privacy that should be further studied. Access control policy (also access policy) is part of an organization’s security policy. In order to verify the access control policy, organizations use an access control model.^[2] General security policies require designing or selecting appropriate security controls to satisfy an organization's risk appetite - access policies similarly require the organization to design or select access controls.
