Access Control
In access control, different resources (e.g. files) are monitored. Access to these resources is either permitted or prohibited. Access control ensures that only certain persons or groups of persons can access the resources. Access control ensures that files are kept secure and confidential and protected from access by unauthorised third parties. There are logical and physical access controls. Logical Access Controls restrict access in computer networks and files. Physical access controls are used to protect buildings, IT machines and rooms, for example.
