Self Security Control Assessments (NIST SP 800-171 Rev2) Vs CMMC - The C3PAOs Requirements

In this video, we examine the key differences between the NIST SP 800-171 self-assessment requirements for Defense Industrial Base (DIB) organizations and the mandatory third-party assessment requirements introduced under the Cybersecurity Maturity Model Certification (CMMC) program. The discussion highlights how compliance expectations have evolved—from contractor-performed self-attestations to independent assessments conducted by authorized third-party organizations—and what this shift means for organizations handling Controlled Unclassified Information (CUI) within the DoD supply chain. This video is intended for cybersecurity professionals, ISSOs, GRC practitioners, compliance leads, and DIB contractors seeking clarity on CMMC alignment and assessment readiness. 🔗 Official References & Resources Office of the Under Secretary of Defense for Acquisition & Sustainment (OUSD(A&S)) https://www.acq.osd.mil/asda/dpc/cp/cyber/cmmc.html Cybersecurity Maturity Model Certification (CMMC) https://dodcio.defense.gov/CMMC/ https://dowcio.war.gov/CMMC/About/ https://business.defense.gov/Programs/Cyber-Security-Resources/CMMC-20/ NIST Computer Security Resource Center (CSRC) https://csrc.nist.gov/publications/sp800 📌 Support the Channel Subscribe to KamilSec https://www.youtube.com/c/KamilSec Patreon – Channel Support https://www.patreon.com/kamilSec KamilSec (KS) Merchandise https://kamilsec.creator-spring.com/ Buy Me a Coffee https://buymeacoffee.com/kamilsec CashApp: $Kamilzak Zelle: kaamilzak@gmail.com Paypal: https://paypal.me/MZakari Thank You!!! ************************************************************* Connect with me on Social Media: Twitter: https://twitter.com/Kamilzak_1​ Instagram: @Kamilzak1
