Limit physical access to data rooms

Putting sensitive equipment together in dedicated rooms (or dedicated technical areas), properly secured against attempts at illegal access, increases the resistance to security loopholes that require access to hardware: theft, sabotage, making copies, etc.

By properly restricting physical access to sensitive resources, several security risks are mitigated. Most notably: theft, sabotage, installation of spyware or spy tech, making copies of drives, etc.
