If your business handles sensitive government information, it’s imperative you understand what NIST SP 800-171 is and how it impacts your business. Adequate knowledge of NIST 800-171 will help you evaluate your organization’s state of compliance and identify any deficiencies requiring immediate remediation.
What is NIST 800-171?
NIST SP 800-171 is a set of guidelines published by the National Institute of Standards and Technology (NIST) to “ensure that sensitive federal information remains confidential when stored in nonfederal information systems and organizations.”
What is the purpose of NIST 800-171?
The main purpose of NIST 800-171 is to strengthen the whole federal supply chain. The implementation and assessment of the NIST Special Publication (SP) 800-171 is mandatory for any entity and service provider who receives or creates Controlled Unclassified Information (CUI) from or for the U.S. Department of Defense (DOD).
A broad range of organizations must adhere to this cybersecurity regulation since the exploitation of sensitive data poses a national risk, and also since supply chain attacks are common.
What is the latest version of NIST 800-171?
SP 800-171 was published in June 2015 and since then two minor updates were made — one in December 2016 and another in February 2020. The NIST SP 800 171 Revision 1 (Rev 1) was superseded by the SP 800-171 Revision 2 (Rev 2), which is the current version.
NIST is planning an update with NIST SP 800-171 Revision 3 (Rev 3), but the publication date is yet to be announced.
Who does NIST 800-171 apply to?
NIST 800-171 compliance is mandatory for the following entities:
- Government contractors
- Department of Defense contractors (DOD contractors)
- Service providers processing data for government agencies and federal agencies
- Any entity with a federal contract
- Any entity and subcontractor processing federal information
- Health care data processors
- Education entities with access to federal data (such as colleges and universities)
What is Controlled Unclassified Information (CUI)?
According to the U.S. National Archives and Records Administration (NARA), Controlled Unclassified Information (CUI) is “information that requires safeguarding or dissemination controls according to and consistent with applicable law, regulations, and government-wide policies but is not classified under Executive Order 13526 or the Atomic Energy Act, as amended.”
CUI is an umbrella term for information that is not classified as National Security Information but needs some level of protection. Businesses that handle the following information linked to the federal government in any way must comply with the NIST SP 800-171:
- Electronic and paper documents
- Intellectual property
- Proprietary information
- Designs and specifications
What is the difference between NIST 800-171 and NIST 800-53?
The key difference between the two is that while NIST 800-171 relates to non-federal systems and organizations, NIST 800-53 is for federal organizations. However, if your business handles CUI in any form, you do not have to be linked to a federal system to fall under the compliance purview of NIST SP 800-171.
What are the NIST 800-171 requirements?
The core of NIST 800-171 consists of 110 security requirements distributed across 14 distinct requirement families. Each family is comprised of a minimum of one basic requirement and some derived requirements. Here is an overview of the families:
1. Access control
It comprises two basic and 19 derived requirements that ensure only authorized staff have access to CUI.
2. Awareness and training
It comprises two basic and one derived requirement that ensure adequate training and skills are provided to those responsible for protecting CUI.
3. Audit and accountability
It comprises two basic and seven derived requirements that ensure contractors regularly audit, log and protect audit information.
4. Configuration management
It comprises two basic and seven derived requirements to ensure configurations, systems and software are standardized and managed in definable and measurable ways.
5. Identification and authentication
It comprises two basic and nine derived requirements to ensure authorized access is granted only to authorized staff.
6. Incident response
It comprises two basic and one derived requirement to help a business plan its response to a breach and ensures it can resume operations quickly.
It comprises two basic and four derived requirements to ensure vulnerabilities are addressed, holes patched and subsystems function optimally.
8. Media protection
It comprises three basic and six derived requirements that ensure minimum safeguards are in place for CUI-related media.
9. Personnel security
It comprises two basic requirements to ensure contractors, employees and vendors are thoroughly vetted and approved.
10. Physical protection
It comprises two basic and four derived requirements to ensure necessary safeguards are in place for protecting hardware related to CUI.
11. Risk assessment
It comprises one basic and two derived requirements to ensure measures are in place for periodic evaluation and mitigation of security risks.
12. Security assessment
It comprises four basic requirements to periodically test and review security control measures.
13. System and communications protection
It comprises two basic and 14 derived requirements to protect CUI data from unauthorized exposure.
14. System and information integrity
It comprises three basic and four derived requirements to ensure systems and information remains trustworthy and has not been maliciously or accidentally changed.
How do I become NIST 800-171 compliant?
If your business handles CUI, you are expected to implement NIST 800-171 under Defense Federal Acquisition Regulation Supplement (DFARS) Clause 252.204-7012. To ensure your business is compliant with NIST 800-171, you must perform the following actions:
- Conduct a cybersecurity self-assessment.
- Review your organization’s System Security Plan (SSP) and how it handles the covered information system(s).
- Review the 110 security requirements and document if they have been implemented fully, partially or not implemented.
- After completing your NIST 800-171 Basic Assessment, you can score it using the DOD Assessment Methodology.
- Additionally, you can create a Plan of Action and Milestones (POA&M) strategy for all the security practices you marked as “Partially Implemented” or “Not Implemented.”
- Submit your score and additional information to DOD via the Supplier Performance Risk System (SPRS).
Understanding DOD Assessment Methodology
The NIST 800-171 DOD Assessment Methodology is a scoring system to assess a contractor’s implementation of NIST SP 800-171. Each of the 110 security requirements in 800-171 is assigned a weighted subtractor value. If you implement a practice, you get points, with 110 being a perfect score. Some practices are worth 5 points, some 3 and some 1.
How long does it take to become NIST 800-171 compliant?
Establishing compliance with the NIST SP 800-171 is a time-consuming process but given the cost of non-compliance is losing your DOD contracts, it is well worth the time and effort. It could take at least six months to ensure compliance as you work to verify your networks and procedures have the appropriate protections and safeguards in place.
You will also have to ensure each element of your organization that is covered by a commercial and government entity (CAGE) code has been made part of your organization’s SSP.
