NIST SP 800-53 Rev. 5 CP-2(8) — Identify Critical Assets : iCompaas Support

NIST SP 800-53 Rev. 5·Control CP-2(8)·high·Component: Contingency Planning

What this control requires

Identify critical system assets (technical/operational) supporting essential functions to prioritize protection and ensure continuity during contingency operations. This control supports the Identification capability within the Contingency Planning family.
— NIST SP 800-53 Rev. 5, Control CP-2(8)

In plain English

Identify critical system assets (technical/operational) supporting essential functions to prioritize protection and ensure continuity during contingency operations. 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 Contingency Planning, the assessor will trace your implementation back to the catalogue reference (Control CP-2(8)) and look for objective evidence on the latest two assessment cycles.

How to implement

Business Continuity

BC/DR. Define RTO/RPO per service, test backup restoration quarterly, and run a tabletop of full-region failover annually.

Backups. Immutable backups (S3 Object Lock / Azure immutable storage / GCS bucket lock) plus an air-gapped copy for ransomware resilience.

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.
Protection. Document the trigger, the owner and the cadence.
System. Document the trigger, the owner and the cadence.
Control. Document the trigger, the owner and the cadence.
Identify. Document the trigger, the owner and the cadence.
Scope: management, system, functions, protection, critical assets, capability, operations, identification.

Evidence to collect

Policy Document. A signed and version-controlled policy / standard / procedure document.
Infra Scan. Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.

Signed policy or standard documents the safeguard. Focus: Identify Critical Assets.

Common pitfalls

DR plans that have never been tested in earnest, or that depend on an MFA token only one person can produce.
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.
