S 4.43 Fax machine with automatic envelopment sealing system

Initiation responsibility: IT Security Management

Implementation responsibility: Procurer

Fax machines with an automatic envelopment system prevent unauthorised removal and reading of faxes. Incoming faxes are folded so that only the fax header remains visible and are then heat-sealed in a clear envelope. The fax then drops into a lockable box in the fax machine. Only the authorised person who has a key to this box normally has access to the envelopes. Unauthorised cognisance prior to delivery of the fax is only possible by forcibly opening the box or tearing open the heat-sealed envelope and will thus, at the very least, be noticed.

Additional controls:

• Is the purchase of such a machine worthwhile?
