All cabling should be shielded (when possible) to protect against electromagnetic interference (EMI).
Additionally, hide cabling (i.e., under the floor, above cabinets in caged, cable-management systems, etc.) or—at a minimum—protect with (PVC) tubing (or something similar) when possible to protect against unauthorized physical access.
Define, implement and evaluate processes, procedures and technical measures that ensure a risk-based protection of power and telecommunication cables from a threat of interception, interference or damage at all facilities, offices and rooms.
