Name and describe the different elements of access control. Provide an example of each from food Store
The elements of access control are;
1. Authorization – These are the set of actions permitted to a certain identity. In the case of a computer, authorization takes the form of execution permissions tied to a username, read and write. For example, making sales for a food store requires authorization.
2. Authentication – Identification needs authentication. This is ensuring that the identity in use is by the right person. For example, the use of smartcards and encryption keys for food stores.
3. Identification - An access control must provide a way to identify an individual, for it to be effective. It defines the group of users who should access the system. For example, the use of a key to the server closet, a PGP e-mail.
