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.

However, in recent years, access control has extended to digital platforms. Because of this, the protection of external databases to preserve digital security is more important than ever.[1]

Scholars have considered access control to be a very significant aspect of privacy that should be further studied. Access control policy determines what an organization’s security policy will be. In order to verify the access control policy, organizations use an access control model, but the model does not include details on how the security policy is put into place. Having and building a suitable access control model is therefore essential.[2]
