Governance, Risk, and Compliance

NIST 800-171 Compliance

Working with the U.S. government or defense contractors? NIST 800-171 is your must-have blueprint for protecting Controlled Unclassified Information (CUI).

What is NIST 800-171 Compliance?

NIST 800-171 outlines the security requirements for protecting CUI in non-federal systems and organizations. It’s mandatory for contractors and subcontractors working with federal agencies, especially under DFARS and CMMC. The framework includes 110 controls across 14 categories — all designed to safeguard sensitive federal information.

Key Requirements for Compliance

To comply with NIST 800-171 and protect CUI, your organization must meet these critical requirements:

SSP

Plan of Action & Milestones (POA&M)

110 Security Controls

Configuration Management

Personnel Security

Audit & Accountability

SSP

Maintain a living document that outlines your system’s boundaries, operating environment, and security controls.

Plan of Action & Milestones (POA&M)

Document any gaps in control implementation and how you plan to fix them. It’s your official remediation roadmap for compliance.

110 Security Controls

Implement controls across 14 families, including Access Control, Risk Assessment, and Incident Response. Each control supports confidentiality, integrity, and availability.

Configuration Management

Track and control changes to software, hardware, and system settings. This ensures consistency and reduces vulnerability.

Personnel Security

Conduct background checks and manage user access based on role and need. These safeguards help prevent insider threats.

Audit & Accountability

Monitor system activity and maintain logs that trace user actions. This helps detect, investigate, and respond to suspicious behavior.
