S 5.26 Announcing fax messages via telephone

Initiation responsibility: IT Security Management, Superiors

Implementation responsibility: Fax sender

Important fax messages of a confidential or financial nature (e.g. tenders) or involving deadlines must be announced to the recipient before dispatch (e.g. via telephone). This allows the recipient to pick up the fax message from the fax machine before other parties are able to do so.

Superiors should instruct users to announce confidential and important fax messages.

Additional controls:

• Are important fax messages announced beforehand?

• Are users instructed to do so?
