Access control is a security technic that regulates access to resources on a system. There are two types of access control:
- Physical that limit access to buildings, rooms, physical assets, etc.
- Logical that limit connection to networks, system files and data.
All access control systems perform authentication in order to verify that the identity of the user is correct and he/she has permission to access resources.
