Understanding NIST 800-171 Compliance
The National Institute of Standards and Technology (NIST) Special Publication 800-171 (NIST SP 800-171) is a set of security requirements designed to help non-federal organizations protect the confidentiality, integrity, and availability of Controlled Unclassified Information (CUI) in their custody.
The NIST Special Publication 800-171 establishes cybersecurity requirements for best practices as well as protecting Controlled Unclassified Information (CUI) in non-federal systems. Designed for defense contractors, research institutions, and other organizations handling government contracts, this framework outlines 110 security controls across 14 families — from access control to system integrity.
As CUI becomes increasingly important both with regard to CMMC and as general secure handling of sensitive data, NIST 800-171 compliance is no longer optional for organizations working with federal agencies. The standards help safeguard sensitive government data while demonstrating your commitment to information security.
CyberCrest specializes in NIST 800-171 compliance consulting, helping organizations implement these critical controls, prepare for assessments, and maintain continuous compliance in line with DoD requirements. Our experts guide you through each requirement to confirm that your systems meet the stringent protection standards for handling CUI.
Frequently asked questions
How long does achieving NIST 800-171 compliance typically take?
Depending on existing security maturity and resources, aligning with NIST 800-171 can take anywhere from three to twelve months or longer.
Who specifically needs NIST 800-171 compliance?
Organizations handling Controlled Unclassified Information (CUI) in support of federal contracts, particularly DoD contractors and subcontractors, must comply with NIST 800-171 requirements.
What documentation is required for NIST 800-171 compliance?
Primary documentation includes a System Security Plan (SSP), Plan of Action & Milestones (POA&M), policies, procedures, and records of implemented security controls.
Is third-party auditing mandatory under NIST 800-171?
Currently, NIST 800-171 does not require third-party certification audits; however, self-assessments and documentation demonstrating compliance are required for DoD contracts.
What happens if an organization fails to comply with NIST 800-171?
Noncompliance risks losing eligibility for DoD contracts or subcontracting opportunities, and it may negatively impact competitive positioning and reputation.
What are some of the key security domains within NIST 800-171?
Major domains include access control, incident response, configuration management, identification and authentication, media protection, and security assessment.
Does CyberCrest provide formal NIST 800-171 assessments?
CyberCrest specializes in readiness support, gap assessments, and advisory services for NIST 800-171 compliance; formal government-mandated assessments typically remain internal/self-administered.
Can I use existing security measures for NIST 800-171 compliance?
Yes, existing controls can be leveraged, but they must explicitly align with and adequately address specific NIST 800-171 security requirements.
How often should NIST 800-171 compliance be reviewed?
Organizations should perform compliance reviews at least annually or whenever significant changes occur in operations, systems, or business scope.
How does NIST 800-171 differ from the Cybersecurity Maturity Model Certification (CMMC)?
NIST 800-171 defines specific security controls to protect CUI. CMMC incorporates these controls and adds a formal third-party assessment and certification requirement.
What’s involved in creating a System Security Plan (SSP)?
An SSP describes system boundaries, security requirements implementation, operational roles, and details how your organization protects CUI according to NIST 800-171 guidelines.
What is a Plan of Action & Milestones (POA&M)?
A POA&M documents security gaps identified during assessments, outlines corrective actions, assigns responsibilities, and provides timelines for achieving compliance.
Does compliance with NIST 800-171 apply to subcontractors?
Yes, subcontractors handling or processing CUI must also adhere to NIST 800-171 standards, as compliance requirements cascade through the contracting supply chain.
Does CyberCrest assist with ongoing compliance management for NIST 800-171?
Yes, CyberCrest’s NIST 800-171 consultants provide ongoing advisory services, compliance reviews, and support to help organizations continuously maintain adherence to NIST 800-171 requirements.
