S 5.29 Periodic checks of destination addresses and logs

Initiation responsibility: IT Security Management

Implementation responsibility: Fax Officer

Programmable keys for abbreviated dialling and destination addresses should be periodically checked to determine whether the programmed fax numbers still coincide with the actual ones and whether they are still required. This prevents incorrect fax numbers input by strangers from being used instead of the correct numbers for extended periods and allows modifications to the desired destination number to be recognised at an early stage.

Additional controls:

• Are the stored subscriber numbers checked periodically?
