This control supports the Surveillance Audit Toolkit capability within the Risk Assessment family. > > — NIST SP 800-53 Rev. 5, Control RA-6 ### In plain English Conduct technical surveillance countermeasures surveys to detect surveillance threats and assess security weaknesses at defined locations and intervals or upon specific triggers. In practice, this means you can prove you policy management-level controls on a defined cadence. ## Why it matters SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed. This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation. ## What an auditor looks for A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan. Within **Risk Assessment**, the assessor will trace your implementation back to the catalogue reference (Control RA-6) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Physical Security **Inheritance.** For cloud-only operations, inherit physical controls from the provider's SOC 2 / ISO 27001 report and document the inheritance in the SoA. #### Policy Management **Docs.** Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA. ### Operational checklist - **Policy.** Document the trigger, the owner and the cadence. - **Audit.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Physical.** Document the trigger, the owner and the cadence. - **Control.** Document the trigger, the owner and the cadence. - **Scope:** management, assessment, capability, threats, surveillance, security policy, assess, surveillance countermeasures survey. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Technical Surveillance Countermeasures Survey. ## Common pitfalls - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**NIST SP 800-171 Rev. 3 3.11.4** — Risk Response](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-11-4-risk-response) - [**ISO/IEC 27001:2022 A.7.3** — Securing offices, rooms and facilities](https://support.icompaas.com/compliance/iso-27001-2022/a-7-3-securing-offices-rooms-and-facilities) - [**HIPAA (45 CFR Part 164) 164.308(a)(5)(i)** — Security Awareness and Training](https://support.icompaas.com/compliance/hipaa/164-308-a-5-i-security-awareness-and-training) - [**BSI C5:2020 SP-01** — Documentation, communication and provision of policies and instructions](https://support.icompaas.com/compliance/bsi-c5-2020/sp-01-documentation-communication-and-provision-of-policies-and-instructions) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control RA-2** — Security Categorization](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-2-security-categorization) - [**Control RA-5(4)** — Discoverable Information](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-4-discoverable-information) - [**Control RA-10** — Threat Hunting](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-10-threat-hunting) - [**Control CP-6(3)** — Accessibility](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-6-3-accessibility) - [**Control RA-7** — Risk Response](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-7-risk-response) - [**Control RA-5(2)** — Update Vulnerabilities To Be Scanned](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-2-update-vulnerabilities-to-be-scanned) ## References - [NIST Computer Security Resource Center — NIST SP 800-53 Rev. 5](https://csrc.nist.gov/Projects/risk-management/sp800-53-controls) - Catalogue identifier: `Control RA-6` Topics: governance riskphysical securitypolicy management ## Related compliance guidance - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): Start with the full NIST SP 800-53 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-171 and CMMC: a practical guide to protecting CUI in the cloud](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3): If your obligation is protecting CUI in your own systems for a federal or defence contract, this derived subset — not the full catalogue — is the requirement. - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Most commercial SaaS already hold a SOC 2 Type 2, and FedRAMP 20x Class A is designed for providers that have one.
