Protecting sensitive government data is more than just a compliance requirement—it’s a responsibility that every defense contractor must take seriously. The DFARS cybersecurity requirements were introduced to help organizations handling Controlled Unclassified Information (CUI) adopt strong security measures and reduce risks of data breaches. If your business works with the Department of Defense (DoD), you must understand the Cyber DFARS Clause and what it means for your organization.

In this blog, Oriento provides a clear, easy-to-follow DFARS cybersecurity checklist to help you protect CUI DFARS data effectively and prepare for DFARS CMMC compliance.

What is the Cyber DFARS Clause?

The Cyber DFARS Clause (DFARS 252.204-7012) requires contractors and subcontractors to implement cybersecurity safeguards based on NIST SP 800-171. Its purpose is to ensure that all companies in the defense supply chain can adequately protect CUI DFARS data from cyber threats.

Failure to comply with the DFARS cybersecurity requirements can result in loss of contracts, penalties, and reputational damage. That’s why having a clear checklist in place is critical for both compliance and operational security.

DFARS Cybersecurity Checklist

Here are the key steps your organization should follow to meet the DFARS cybersecurity requirements:

1. Identify and Protect CUI

The first step is identifying where CUI DFARS data is stored, processed, or transmitted in your environment. Create an inventory and ensure it is only accessible to authorized personnel. Use encryption and strict access controls to protect it.

2. Implement NIST SP 800-171 Controls

Compliance with the Cyber DFARS Clause means aligning your security program with the 110 controls outlined in NIST SP 800-171. These include access management, incident response, auditing, system integrity, and continuous monitoring.

3. Multi-Factor Authentication (MFA)

Enable MFA for all systems that store or access CUI DFARS data. This is one of the most effective defenses against unauthorized access and is a clear expectation under DFARS CMMC requirements.

4. Incident Reporting

If a cyber incident occurs, DFARS 252.204-7012 requires reporting to the DoD within 72 hours. Make sure your organization has an incident response plan in place and knows how to meet this reporting obligation.

5. Regular Risk Assessments

Conduct routine assessments of your security environment to identify vulnerabilities. These assessments not only help in meeting DFARS cybersecurity standards but also demonstrate due diligence during a DFARS CMMC assessment.

6. Continuous Monitoring

Cyber threats evolve constantly. Implement real-time monitoring tools to detect and respond to anomalies quickly. Continuous monitoring is a best practice and supports compliance with the Cyber DFARS Clause.

7. Partner with a Trusted Advisory

Achieving and maintaining compliance can be complex. Working with a trusted partner like Oriento ensures you have the right guidance, assessments, and solutions to stay aligned with DFARS cybersecurity standards.

Why DFARS CMMC Matters

While the Cyber DFARS Clause requires immediate compliance with NIST SP 800-171, the DFARS CMMC framework (Cybersecurity Maturity Model Certification) goes one step further by introducing third-party certification. This means defense contractors must not only claim compliance but also prove it through a formal audit.

By following the DFARS Cybersecurity checklist, your business will be well-prepared to transition smoothly into the DFARS CMMC requirements and avoid disruptions in contract eligibility.

Final Thoughts

Protecting CUI DFARS is not just a compliance task—it’s essential for national security and your organization’s long-term success. By following the DFARS Cybersecurity checklist, aligning with the Cyber DFARS Clause, and preparing for DFARS CMMC, defense contractors can secure sensitive data and maintain trust with the Department of Defense.
