Understanding NIST SP 800-171 and SP 800-172

Safeguarding Controlled Unclassified Information (CUI) is more critical than ever, and NIST SP 800-171 provides the necessary framework to ensure its protection across non-federal systems. With evolving threats, the 14 security families outlined in the standard help organizations maintain confidentiality, resilience, and compliance. For high-risk environments, NIST SP 800-172 builds upon these requirements, introducing enhanced protections against advanced persistent threats. Implementing these standards may be challenging, but organizations that take a proactive approach will not only strengthen their security posture but also gain trust and credibility in today’s cybersecurity landscape.
