NIST SP 800-53 Rev. 5 IA-5(7) — No Embedded Unencrypted Static Authenticators

What this control requires

Ensure unencrypted static authenticators are not embedded in applications, scripts, or storage to prevent unauthorized access. This control supports the Application Security System capability within the Identification and Authentication family.

In plain English

Ensure unencrypted static authenticators are not embedded in applications, scripts, or storage to prevent unauthorized access. In practice, this means you can prove you access 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 Identification and Authentication, the assessor will trace your implementation back to the catalogue reference (Control IA-5(7)) and look for objective evidence on the latest two assessment cycles.

How to implement

Code Review Testing

Pipeline. Require at least one human reviewer plus passing CI (lint, type, unit, security scan) before merge — protected branches enforce this.

Operational checklist

• Access. Document the trigger, the owner and the cadence.
• Security. Document the trigger, the owner and the cadence.
• Review. Document the trigger, the owner and the cadence.
• Authentication. Document the trigger, the owner and the cadence.
• No. Document the trigger, the owner and the cadence.
• Scope: management, authentication, system, application, identity, review, capability, authenticators.

Evidence to collect

• Identity Scan. IAM / IdP exports — Entra ID, Okta, IAM Identity Center, Workspace directory — showing accounts, roles, MFA state and last sign-in.

Identity analytics (Okta, SailPoint, Access Analyzer) demonstrates least-privilege. Focus: No Embedded Unencrypted Static Authenticators.

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.
