An audit notice doesn’t have to send your team into panic mode. With steady preparation, you can walk into a DFARS assessment confident that your systems, documentation, and controls are ready to hold up under scrutiny. The trick is starting early and knowing exactly what assessors want to see. Many defense contractors lean on DFARS consulting to guide that process, but even a lean internal team can succeed with the right roadmap. Below, we break down the key steps that turn audit stress into audit readiness.
Review Your NIST SP 800-171 Controls
DFARS compliance centers on NIST SP 800-171, which lists security controls designed to protect Controlled Unclassified Information (CUI). Your first move is a careful review of each one.
Go control by control and confirm how you meet it. Look at access management, encryption, audit logging, and incident response. Don’t assume a control is satisfied just because you bought a tool—verify that it’s configured correctly and actually working. This review sets the foundation for everything else in your preparation.
Update Your System Security Plan
Your System Security Plan (SSP) is the document assessors reach for first. It describes your environment and explains how you implement each of the 110 controls.
An outdated SSP raises immediate red flags. If your network, software, or processes have changed since you last touched the plan, update it now. A strong SSP is detailed, current, and honest. It should map your systems, define your CUI boundaries, and show a clear picture of your security posture. Treat it as a living document, not a one-time formality.
Conduct a Gap Assessment
Once your SSP reflects reality, compare that reality against the full DFARS requirements. A gap assessment reveals where you fall short before an assessor does.
Work through each control and mark it as met, partially met, or missing. For every gap, create a Plan of Action and Milestones (POA&M) that spells out what you’ll fix, how, and by when. Assessors expect to see gaps handled this way. A well-documented POA&M shows you understand your weaknesses and have a credible plan to close them.
Organize Your Documentation
Even solid security fails an audit when the paperwork is a mess. Assessors need evidence, and scrambling to find it wastes time and erodes their confidence in you.
Gather and organize your key documents ahead of time, including:
- Access control logs and user permission records
- Configuration and patch management reports
- Incident response plans and training records
- Policies and procedures tied to each control family
Store everything in a clear, logical structure so you can produce any item on request. Good organization signals discipline and makes the entire audit run smoother.
Test Your Incident Response
DFARS requires you to detect, report, and respond to cyber incidents within tight deadlines. Don’t wait for a real breach to find out your plan doesn’t work.
Run a tabletop exercise that walks your team through a simulated incident. Confirm that everyone knows their role and that you can meet the 72-hour reporting window. A tested plan proves to assessors that your response capability is more than words on paper.
Work With Experts
DFARS requirements are dense, and the stakes are high. Bringing in specialists helps you catch blind spots, interpret tricky controls, and prepare with confidence.
Experienced advisors have seen dozens of audits. They know what assessors probe hardest and how to present your evidence effectively. That guidance can mean the difference between a smooth assessment and a costly round of findings.
