At IBSS, we work with defense contractors of all sizes who are trying to make sense of evolving cybersecurity requirements, even those without a cybersecurity background. So, let’s break it down in plain language.
What Is NIST SP 800-171?
NIST SP 800-171 is a set of cybersecurity requirements from the National Institute of Standards and Technology (NIST). It outlines how organizations should protect Controlled Unclassified Information (CUI)—sensitive but unclassified information that the federal government wants to keep secure. If your organization stores, processes, or transmits CUI for the DoD, you’re required to implement these security practices.
Why Does it Matter?
Compliance with NIST SP 800-171 isn’t optional. It’s a mandatory requirement for contractors and subcontractors handling CUI. It also plays a foundational role in Cybersecurity Maturity Model Certification (CMMC), which is being rolled out across the defense industrial base. Failing to comply could mean losing out on future contracts or being removed from existing ones.
What’s in the Framework?
The standard includes 110 security controls organized into 14 families, such as:
- Access Control: Who can see sensitive information?
- Incident Response: How do you detect and respond to cyberattacks?
- System and Communications Protection: How is your data secured in transit?
- Media Protection: How is data stored, disposed of, or transferred?
These aren’t just technical requirements. They also involve processes, policies, and training.
What DoD Contractors Need to Do
If you’re a DoD contractor handling CUI, you should:
- Assess your current environment against the 110 controls.
- Create a System Security Plan (SSP) that documents your compliance.
- Develop a Plan of Action & Milestones (POA&M) to fix any gaps.
- Submit your SPRS score to the DoD, which reflects your level of implementation.
This isn’t a one-and-done exercise. You’ll need to maintain these controls and keep documentation current.
