4.3.4 Technical Infrastructures Room

Description

As a rule, technical infrastructure rooms house those equipment items and facilities which require no, or infrequent, human attendance. Usually, these will be distributors of internal supplies (e.g. PTT cable transfer room, high-tension lead-in room, medium-voltage lead-in room, low-voltage main distributor). In instances, these rooms may also house the fuses for power supply. Installation of other devices/equipment (uninterruptible power supply, star coupler, etc.) is also conceivable. Even a network server might be accommodated here if a specific room (Chapter 4.3.2, Server Room) is not available.

Threat Scenario

The following typical threats (T) are assumed as regards IT baseline protection of a technical infrastructure room:
