BSI C5 · Control PS-01 · Priority: high · Component: Physical Security

### What this control covers

Documents security requirements for premises per SP-01, addressing risks like unauthorized access, fire, and power failure based on risk assessments. Ensures data center compliance with technical standards and verifies third-party facilities to protect cloud infrastructure.

### Why it matters

Risk is the language an executive team understands; this control connects technical reality to board-level decisions and budget allocation.

### How to implement

#### AWS

Codify the policy intent as **SCPs, AWS Config conformance packs, and Security Hub standards** so the cloud enforces what the document says.

#### Azure

Codify in **Azure Policy initiatives** (built-in regulatory compliance for CIS, ISO 27001, SOC 2, HIPAA) and assign at management-group level.

#### On-premises

Maintain a policy library with a documented review cadence (annual minimum); store in your GRC tool with attestation tracking. Map each policy to controls so an audit pull cites the exact policy clause.

### Evidence to collect

-   `vendor_risk_management` — See the iCompaas Evidence library for the canonical source for this evidence type.
-   `policy_document` — A signed, version-controlled policy stating leadership intent and the named owner.
-   `infra_scan` — See the iCompaas Evidence library for the canonical source for this evidence type.

Third-party risk management evidence (assessments, contracts, due diligence) shows supplier oversight. Signed policy or standard documents the safeguard. Focus: Physical Security and Environmental Control Requirements.

### Quick checklist

-   Risk — Management
