Is NIST 800-172 Compliance Required for FedRAMP, CMMC, ITAR or Similar Regulations?

Organizations often wonder how to comply with NIST 800-172, especially when considering its overlap with other frameworks like FedRAMP, CMMC, and ITAR. Let’s take a closer look at the relationship between NIST 800-172 and these individual regulations.

NIST 800-172 and CMMC

Compliance with NIST SP 800-172 is not explicitly required for Cybersecurity Maturity Model Certification (CMMC) 2.0 compliance. However, it’s important to understand the relationship between these standards and frameworks to fully grasp their implications. CMMC 2.0, which is designed to protect controlled unclassified information (CUI) and federal contract information (FCI) within the Defense Industrial Base (DIB), includes three levels of cybersecurity maturity. CMMC Level 1 (Foundational) is aligned with the 17 basic security practices found in FAR 52.204-21. CMMC Level 2 (Advanced) aligns closely with the 110 security controls defined in NIST SP 800-171. CMMC Level 3 (Expert) is influenced by standards such as NIST SP 800-172 but does not contain a direct one-to-one mapping. In brief, CMMC Level 3 does not explicitly mandate full compliance with NIST SP 800-172.

NIST 800-172 and FedRAMP

FedRAMP (Federal Risk and Authorization Management Program) is a U.S. government program that standardizes security assessments, authorizations, and continuous monitoring for cloud products and services. FedRAMP compliance primarily focuses on adhering to the controls outlined in NIST SP 800-53, tailored to the specific needs and risks associated with cloud services. NIST SP 800-172 compliance is not a specific requirement for FedRAMP authorization, however, it is possible for future updates to integrate additional standards or requirements based on evolving security needs and legislative changes.

NIST 800-172 and ITAR

The International Traffic in Arms Regulations (ITAR) is a set of U.S. government regulations that control the export and import of defense-related articles and services. ITAR compliance mainly focuses on the protection of technical data and defense-related information to ensure that it does not fall into the hands of foreign entities without appropriate authorization. While ITAR does not mandate NIST 800-172 compliance specifically, organizations that handle both ITAR-related data and controlled unclassified information might find it beneficial to implement NIST 800-172 or NIST 800-171 standards to enhance their overall security posture. ITAR compliance often involves multiple layers of controls, including physical security, personnel vetting, access control, and cybersecurity measures. Using NIST frameworks can assist in meeting some of these cybersecurity requirements, but adhering strictly to NIST 800-172 is not a regulatory requirement under ITAR.

So, while NIST 800-172 compliance is not explicitly required for CMMC, FedRAMP, or ITAR, organizations that demonstrate NIST 800-172 compliance or even adhere to some NIST 800-172 standards, can significantly fortify their security posture and facilitate meeting multiple regulatory requirements.
