Controlled Unclassified Information handling
Controlled Unclassified Information handling in Defense and Government Contracting is under direct federal pressure from the U.S. Department of Defense and the National Institute of Standards and Technology, whose NIST SP 800-171 revision cycle and the Defense Federal Acquisition Regulation Supplement Rule 2019-D041 have pushed contractors to overhaul how CUI is identified, marked, and transmitted across supply chains. The Cybersecurity Maturity Model Certification 2.0 final rule, published by the Department of Defense in late 2024, sets enforceable third-party assessment requirements that were absent from earlier self-attestation regimes. Contractors with gaps in their System Security Plans are now the primary audit target.
Watch
- CMMC 2.0 final rule phased implementation deadlines for Level 2 contractors
- NIST SP 800-171 Revision 3 control changes requiring SSP updates before contract renewal
- DoD DFARS 252.204-7012 clause enforcement in subcontractor flow-down agreements
- National Archives and Records Administration CUI Registry category expansions affecting DoD program data
- Self-attestation vs. third-party assessment thresholds shifting under pending DFARS proposed rule
