A Beginner’s Guide to PO&AM Remediation for CMMC Compliance

The Cybersecurity Maturity Model Certification (CMMC) is a unified standard for implementing cybersecurity across the defense industrial base. For any organization seeking to work with the Department of Defense (DoD), CMMC compliance is not just beneficial, but mandatory. One crucial aspect of achieving compliance is PO&AM remediation. Plan of Actions & Milestones (PO&AM) is a document that outlines how an organization plans to address deficiencies in their cybersecurity practices and meet the specific security requirements.

Here’s a step-by-step beginner’s guide to PO&AM remediation for CMMC compliance:

Step 1: Understand CMMC and Its Importance

Before tackling PO&AM, it’s important to have a clear understanding of the CMMC framework and why it’s crucial for your organization.

Step 2: Conduct a Gap Analysis

Perform a thorough cybersecurity gap analysis to identify where your current cybersecurity practices do not meet CMMC requirements.

Step 3: Develop Your PO&AM

Based on the gap analysis, create your Plan of Actions & Milestones. Ensure it details the deficiencies found, along with corresponding actions, resources required, and timelines for remediation.

Step 4: Prioritize Remediation Tasks

Organize the tasks by priority, starting with the most critical security gaps that pose the highest risk to your organization’s cybersecurity posture.

Step 5: Assign Responsibility

Make sure that each action item in your PO&AM has a responsible party assigned to oversee the task to completion.

Step 6: Implement Remediation Efforts

Proceed to work on the action items. This could involve updating software, changing procedures, training staff, or other activities critical to mitigating vulnerabilities.

Step 7: Monitor Progress

Regularly check on the status of each milestone to ensure tasks are being completed within the outlined timeframes.

Step 8: Update PO&AM Regularly

As you complete tasks and improve your cybersecurity stance, continuously update your PO&AM to reflect these changes.

Step 9: Validate Remediation Measures

Through testing and reviews, validate that the remediation measures you’ve implemented are effectively meeting the security requirements.

Step 10: Prepare for CMMC Assessment

Once you’ve addressed all deficiencies and updated your PO&AM, prepare for a formal CMMC assessment by a certified third-party assessor organization (C3PAO).


By following this guide, you’re setting a solid foundation for CMMC compliance, staying ahead of cybersecurity threats, and ensuring your organization remains competitive for DoD contracts.

Remember, cybersecurity is a continuous process, and your PO&AM is a living document that will need attention and updates as new threats emerge and requirements evolve. Stay proactive and maintain the standards set by CMMC to protect sensitive data and support national security interests.
