Recent DFARS class deviations associated with the FAR and DFARS overhaul reorganized several cybersecurity clauses, leading to confusion about government contractor self-assessment requirements. Although certain DFARS provisions were removed or renumbered, government contractors handling Federal Contract Information (FCI) must still conduct CMMC Level 1 self-assessments and post results in Supplier Performance Risk System (SPRS).
Highlights
- DFARS Clause Reorganization. In January 2026, DoD began issuing class deviations on 31 FAR parts and related DFARS as part of the DFARS Revolutionary FAR overhaul. While there are many revisions, a significant change was the relocation of some of the cybersecurity procedures to FAR 40 and DFARS 240 Information Security and Supply Chain Security Requirements and renumbering of the cybersecurity provisions and clauses in the related sections.
- Provision/Clause Renumbering. Some of the cybersecurity provisions and clauses were relocated and renumbered under the DFARS Revolutionary FAR overhaul. For example, the clause at FAR 52.204-21 was changed to FAR 52.240-93, and the clause at DFARS 252.204-7020 was changed to DFARS 252.240-7997 and removed the requirement for the basic self-assessment.
- Self-Assessment Requirement. Although the NIST SP 800-171 Basic Self-Assessment requirement was removed from DFARS 252.204-7020 when the clause was relocated to DFARS 252.240-7997, contractor self-assessments were not eliminated. A self-assessment is still required for contractors required to comply with CMMC Level 1.
- CMMC Level 1 Requirements. Contractors handling Federal Contract Information on DoD contracts are required to comply with CMMC Level 1. This requires contractors to prepare a self-assessment against a minimum of the 15 safeguarding controls in FAR 52.240-93 and post the score in the Supplier Performance Risk System.
- Operational Impact. Contractors need to review the DFARS Revolutionary FAR Overhaul class deviations and effective dates to gain an understanding of the changes and the impact on policies, subcontract flowdowns, templates, and flowdown clauses.
As part of the DFARS Revolutionary FAR Overhaul Class Deviations, the Department of Defense (DoD) adopted the FAR Council’s changes. It began issuing class deviations to DFARS text with effective dates as early as January 23, 2026. While there are many changes, we are focusing on the class deviation for the revision and renumbering of the cybersecurity-related clauses, which became effective February 1, 2026.
A major change in the FAR and DFARS overhaul is the creation of FAR Part 40 and DFARS Part 240 Information Security and Supply Chain Security. These new parts consolidate some of the cybersecurity, prohibition, and supply chain risk management requirements previously located in FAR Part 4 and DFARS 204 into FAR Part 40 and DFARS Part 240, respectively.
What Changes are Related to Cybersecurity?

- Flow down clause to subcontractors if handling FCI
DFARS Clause Changes
- DFARS 252.204‑7019 Notice of NIST SP 800-171 DoD Assessment Requirements has been eliminated.
- DFARS 252.204-7020 has been renumbered to DFARS 252.240-7997 but maintains the same title, “NIST SP 800-171 DoD Assessment Requirements.”
- Solicitation Provision moved from DFARS 204.7304 to DFARS 240.370-5
- Requirement for a basic self-assessment of NIST SP 800-171 security controls and post score in Supplier Performance Risk System (SPRS) has been removed
- Medium and High assessments conducted by the Government in accordance with NIST SP 888-171A did not change
- DFARS 252.204-7012 Safeguarding Covered Defense Information and Cyber Incident Reporting
- No change to the requirements
- Solicitation Provision moved from DFARS 204.7304 to DFARS 240.370-5
- DFARS 252.204-7021 Contractor Compliance with the Cybersecurity Maturity Model Certification Level Requirements

As a result of the DFARS changes, some companies have circulated article titles claiming, “government contractors are no longer required to conduct basic self‑assessments or upload their scores into SPRS.” These article titles unintentionally suggest that the removal or restructuring of prior DFARS clauses (such as 252.204‑7019/7020) has eliminated the Basic Self-Assessment requirement. Government contractors handling covered defense information were required to implement all 110 security controls per NIST SP 800-171, complete a Basic Self-Assessment and post the score in SPRS. While DFARS 252.204-7997 removes the NIST SP 800-171 Basic Self-Assessment requirement, it does not eliminate the self-assessment requirement altogether.
Where Does the Self-Assessment Still Reside?
DFARS 252.204-7021 Contractor Compliance with the Cybersecurity Maturity Model Certification (CMMC) Level Requirements establishes a self-assessment requirement for government contractors. Under this clause, contractors and subcontractors with Department of Defense (DoD) contracts that handle Federal Contract Information (FCI) are required to comply with CMMC Level 1.
CMMC 1 requires contractors to conduct a self-assessment against the 15 basic safeguarding security controls in FAR 52.240-93, and post the resulting score to SPRS. This streamlined self-assessment is advantageous for contractors whose information systems only process FCI. In contrast to the former NIST SP 800‑171 Basic Self‑Assessment, which required evaluating and scoring 110 security controls, CMMC Level 1 imposes a significantly reduced compliance burden. Contractors that handle CUI on DoD contracts will continue to be subject to NIST SP 800-171 assessment requirements under CMMC Level 2.
Takeaways
Government contractor self-assessments of security controls have not been removed in their entirety. The requirement for a Basic Self‑Assessment using the 110 security controls in NIST 800 SP-171 has been eliminated. But if you have a DoD contract/subcontract and handle FCI, you will need to meet CMMC Level 1, prepare a self-assessment of the 15 security controls in FAR 52.240-93, and post the score in SPRS.
Government contractors should:
- Update internal references from 52.204‑21 to 52.240‑93
- Remove DFARS 252.204-7019 and update references from 252.204-7020 to DFARS 252.240-7997
- Review templates, subcontracts, and flowdowns to ensure the new clause numbers are flowed down if applicable
- Verify that the 15 safeguarding controls are implemented and documented
- Ensure subcontractors handling FCI are also flowing down the updated clause

Frequently Asked Questions (FAQs)
- Did the DFARS Revolutionary FAR Overhaul eliminate cybersecurity self-assessments for contractors? No. The DFARS overhaul removed the basic self-assessment to comply with the 110 controls in NIST SP 800-171, but it did not eliminate self-assessments entirely. Contractors with DoD contracts handling Federal Contract Information must comply with CMMC Level 1 which requires a self-assessment.
- Who must complete a CMMC Level 1 self-assessment? Contractors and subcontractors that handle Federal Contract Information on DoD contracts must comply with CMMC Level 1; which requires a self-assessment of the 15 basic safeguarding controls in FAR 52.240-93. The score is posted in the Supplier Performance Risk System (SPRS).
- How is the current self-assessment different from the previous NIST SP 800-171 assessment? Contractors performing DoD contracts must complete a self assessment demonstrating compliance with 15 basic safeguarding controls when processing Federal Contract Information. Prior to this change, contractors that handled FCI had to complete a self-assessment and comply with the 110 security controls in NIST SP 800-171 and this requirement was removed from DFARS 252.240-7997.
- Why should government contractors review their policies and contracts after these changes? DoD has issued class deviations accepting 31 sections of the DFARS Revolutionary FAR overhaul beginning in January 2026. These class deviations include effective dates of the FAR and related DFARS changes. It is important to review and understand the changes, effective dates and impact on your contracts. While there are many changes, this blog identifies significant changes related to cybersecurity clauses.
