1. Understand Your Required Level.

Determine which CMMC level (1–3) applies to your organization based on the type of federal contracts and information (FCI or CUI) you handle.

 

  1. Conduct a Readiness Assessment

 Perform a gap analysis against the CMMC practices to identify missing controls and  processes. Document all deficiencies clearly.

 

  1. Build a System Security Plan (SSP)

Create or update your SSP that describes how your organization meets each control. This document is key for auditors.

 

  1. Develop a Plan of Action and Milestones (POA&M)

For any gaps found, record the remediation plan, responsible person, and timeline in a POA&M.

 

  1. Implement Required Security Controls

Apply the necessary technical, operational, and policy-level controls — such as MFA, encryption, logging, and access restrictions.

 

  1. Train Your Employees

Security awareness is vital. Conduct role-based training so employees understand their responsibilities under CMMC.

 

  1. Document Everything

Keep thorough records and screenshots for every practice implemented. Auditors rely heavily on documented evidence.

 

  1. Conduct Internal Audits or Mock Assessments

Run an internal review or hire a CMMC Registered Practitioner (RP) to perform a pre-assessment and simulate audit questions.

 

  1. Address Any Remaining Gaps

Before the real audit, fix any open items in your POA&M. Ensure policies match what’s being practiced day-to-day.

 

  1. Schedule and Pass the Official C3PAO Assessment

Once ready, engage an accredited C3PAO (Certified Third Party Assessor Organization)    to conduct the formal audit and achieve certification.
