S 5.27 Acknowledging successful fax reception via telephone

Initiation responsibility: IT Security Management, Superiors

Implementation responsibility: Fax sender

Recipients should be asked whether important fax messages have been received/printed completely and viewed by them. Employees should be instructed to observe this measure. The receipt confirmation of such fax messages can also be requested by furnishing the fax cover sheet with a distinct and appropriate mark.

It is facilitated on some fax machines by a service feature which consists of the output of individual reports indicating the error during dispatch.

Additional controls:

• Does the agency/company transact fax messages whose correct reception is of particular importance?

• Is the recipient requested to acknowledge the arrival of such fax messages?
