S 1.43 Secure siting of ISDN routers

Initiation responsibility: Head of IT Section, IT Security Management

Implementation responsibility: Administrators

To ensure that ISDN routers cannot be manipulated during their operation, it is absolutely necessary to install them in a secure environment. This can either be a server room (refer to Chapter 4.3.2 Server room) or a server cabinet, if a separate server room is not available (refer to Chapter 4.4 Protective cabinets). Unauthorised persons must not be allowed unsupervised access to ISDN routers.

Additional controls:

• Has it been ensured that ISDN routers can only be accessed by authorised persons, also in cases where regular employees have been substituted temporarily?

• Is every ISDN router installed in a server room or server cabinet?
