NIST 800 171 compliance checklist

NIST 800-171, or NIST SP 800-171, is a guideline issued by the National Institute of Standards and Technology (NIST) for non-federal entities. It outlines rules for securely handling Controlled Unclassified Information (CUI), covering storage, processing, and transmission.  

If your organization does business with the U.S. DoD, you must be NIST 800-171 compliant. It is designed to safeguard CUI in non-federal information systems. It applies to defense contractors or vendors who handle, store, or transmit CUI but are not federal agencies themselves.

Federal agencies often require NIST 800-171 compliance when they work with organizations that handle or store CUI. Non-compliance can lead to fines and penalties, so organizations must take the necessary steps to meet these requirements. 

We have compiled the NIST 800 171 compliance checklist (discussed in the next section) to help you further cement your defense in matters concerning sensitive information.

NIST 800 171 Compliance Checklist

The NIST 800 171 compliance checklist is important as it provides a step-by-step guide to protecting sensitive data. Let’s take a look at those steps:

  • Assess the scope of the contract
  • Identify whether you’re dealing with CUI
  • Classify the data
  • Gather appropriate documentation
  • Conduct a gap analysis
  • Develop and test baseline controls
  • Gather the right evidence
  • Conduct continuous monitoring
  • Train your employees

1. Assess the scope of the contract

Find out if your organization needs to follow the NIST 800-171 standard.

If you are subject to the standard, assess the contract’s scope to determine which NIST 800-171 requirements apply. Understanding the scope is the first thing you must do to know your company’s requirements to stay compliant.

The scope of the contract usually includes:

  • Adherence to the Defense Federal Acquisition Regulation Supplement (DFARS) and other relevant federal regulations
  • Compliance with cybersecurity requirements, such as those outlined in the Cybersecurity Maturity Model Certification (CMMC)
  • Obtaining and maintaining necessary security clearances for personnel
  • Ensuring secure handling and storage of classified information
  • Meeting specified technical and performance standards for products and services
  • Delivering products or services within the agreed timeline and budget

2. Identify whether you’re dealing with CUI

Determine if you’re dealing with CUI. CUI is any information created or held by the Government or another entity on behalf of the Government that must be protected according to laws, regulations, or government policies.

To meet NIST 800-171 compliance, companies must identify whether they are receiving and using CUI and know where it’s stored. This requires a complete audit of the company’s systems and data flows, from employees’ computers to third-party contractors.

Keep an eye out for certain keywords or topics that usually indicate CUI. Terms like “critical infrastructure,” “export control,” or “statutory” are red flags for potential CUI. Hence, you need to understand what typically gets classified as CUI to prepare for the next step in the checklist.

3. Classify the data

Once you identify CUI, categorize it according to its type. This is important because different types of CUI may require varying levels of protection. Knowing the type of CUI involved during a security incident helps quickly determine the appropriate response and remediation actions. 

With that being said, NIST 800-171 recognizes 20 categories of CUI, each with specific standards:

  1. Critical Infrastructure
  2. Defense
  3. Export Control
  4. Intelligence
  5. Procurement and Acquisition
  6. Financial
  7. Law Enforcement
  8. Legal
  9. International Agreements
  10. Natural and Cultural Resources
  11. Nuclear
  12. Provisional
  13. Patents
  14. North Atlantic Treaty Organization (NATO)
  15. Privacy
  16. Proprietary Business Information
  17. Statistical
  18. Tax
  19. Transportation

This step is important because correct classification is necessary to comply with the relevant standards for each category.

4. Gather appropriate documentation

To pass a NIST 800-171 compliance audit, you need thorough documentation showing that all controls and requirements are met. Before the audit, make sure to gather documentation in these areas:

  • System and network architecture: Detailed diagrams and descriptions of your system and network setup.
  • System boundaries: Clear definitions of where your systems begin and end, including interfaces with other systems.
  • Data flow: Documentation showing how data moves through your systems, including where it is stored and processed.
  • Personnel: Records of staff roles and responsibilities, including who has access to CUI and their training records.
  • Processes and procedures: Written procedures and policies for handling CUI, security measures, and incident response plans.
  • Anticipated changes: Information about any planned changes to your systems or processes that could affect compliance.

Does this step seem challenging? 

This is where GRC automation software like Sprinto can help. How does it help? Sprinto’s “Bring Your Own Controls” feature allows companies to configure various frameworks, including NIST, making Sprinto the platform of choice for automating compliance across all frameworks.

Sprinto simplifies the process by offering recommendations and an “Auto-map” feature that automatically links checks to controls, making starting and progressing your compliance journey easy.

5. Conduct a gap analysis 

Before starting the certification process, conduct a pre-assessment to determine your readiness. This includes a gap analysis to identify existing gaps. Focus on primary access control requirements first, then move on to other areas. Here, you need to document any flaws or control gaps so you can address them.

While an experienced NIST partner can help you perform a thorough gap analysis and system review, Sprinto offers a more efficient solution. Designed for cloud-based solutions, Sprinto quickly maps relevant controls to industry standards and identifies gaps.

Sprinto helps you run automated checks, highlights areas for improvement, and guides you toward a more structured approach to NIST 800-171 compliance. This way, your dependence on external bodies also lessens.

6. Develop and test baseline controls

Another difficult task of an organization is to identify the quality of the selected security and privacy controls that would safeguard its mission and business functions from threats and risks. 

These controls must be compliant with the various legal requirements, security standards, and policies in place. If correctly adopted, they will enhance compliance and security standards as required.

Even if your company already has cybersecurity policies, it’s important to ensure that your baseline controls cover all 14 control families listed in NIST 800-171.

Sprinto helps to eliminate this problem by automatically mapping entity-level controls, thereby cutting down the time it takes to carry out this function. 

Assets can be categorized as production and non-production and it is possible to specify security parameters for both types; in some cases, some non-production assets can be excluded from the audit. This makes it possible to develop effective and efficient controls, that respond to the current requirements.

7. Gather the right evidence

Next, gather the necessary evidence for your NIST audit. Focus on the 14 NIST 800-171 criteria to identify the audit requirements you’ll address. While the main goal of collecting evidence during a security incident is to resolve it, this evidence might also be needed for legal proceedings. It’s crucial to document how all evidence, including compromised systems, is preserved.

9. Train your employees

Roy H Williams said “Training is not an expense, but an investment to human capital.” Hence, as a part of getting NIST 800-171 compliant, make sure to develop a detailed training plan that includes:

  • Assessing current knowledge levels of employees
  • Sett clear objectives
  • Create engaging materials such as videos, presentations, handbooks, and interactive tools

This way, you’ll be well on the way to face any cybersecurity challenges.

Importance of Complying With NIST 800 171

Complying with NIST 800-171 is crucial because it sets strong information security standards and guidelines. While preparing for NIST certification can be challenging, understanding its importance helps clarify why it’s worth the effort.

Consider the cybersecurity issues that might keep you up at night:

  • Identifying assets: Not knowing exactly what needs protection.
  • Risk management: Understanding how to handle security risks with your current tools and solutions.
  • Resource allocation: Your team spends too much time on low-impact issues instead of focusing on real risks.
  • Hidden vulnerabilities: Worries about unseen risks and vulnerabilities.
  • Team ownership: Colleagues outside the security team don’t fully understand or take responsibility for critical mitigation tasks.
  • Compliance questions: The board asks if your cybersecurity plan aligns with NIST standards.

NIST 800-171 helps address these challenges. It offers a framework for prioritizing investments and making informed decisions in cybersecurity. In essence, NIST 800-171 guides you through the complexities of cybersecurity, helping you learn from others who have faced similar issues and ensuring your organization meets high-security standards.
