Communication Room Security (PHY-003-R004) - PHY-003

Requirement Details & Guidance

PHY-003-R004 · PHY-003

Why This Requirement Exists

This requirement exists to secure data centers and critical facilities through restricted access, environmental protection, monitoring, inspection, logging, compliance review, and continuous improvement, with specific focus on communication room security, so that physical security controls are proportionate to risk and remain effective.

Implementation Guidance

Establish and document the process for communication room security. Define accountable owners, required inputs and outputs, authorization or validation criteria, review frequency, monitoring, reporting, exception handling, and evidence requirements. Apply controls according to facility, asset, media, personnel, and environmental risk, and integrate with asset management, incident response, business continuity, and facilities processes where applicable.
