T 5.30 Unauthorised use of fax machine or fax server

The unauthorised access to a fax machine or fax server may be exploited for manipulative purposes. Along with the cost incurred for transmitting the fax (charges and material), this may also cause damage by an unauthorised person pretending to use the device as an authorised person (letters with corporate head from the corresponding fax connection).

Moreover, unauthorised persons must be prevented from gaining access to incoming faxes.

Examples:

• A fax machine is installed in the hallway so that anyone passing by may read or steal faxes in an uncontrolled manner.
• For a fax server, the authorisations regarding the stored fax data have been set incorrectly so that unauthorised persons may read third party faxes.
