What is a POAM?

A POAM is more than just a checklist; it's a detailed and dynamic plan that outlines specific steps an organization must take to address and remediate vulnerabilities within their information systems. In the context of compliance frameworks like NIST 800-171 and the Cybersecurity Maturity Model Certification (CMMC), a POAM is essential for documenting the pathway to full compliance.

POAM in Very Simple Terms

Organizations required to comply with compliance standards pertaining to CUI: Controlled Unclassified Information are required to have a document called the POAM standing for Plan of Action and Milestones. This document contains a list of all the controls for the standards they are focusing on that are currently gaps or no implemented. This document allows the company to specify, the reason for the gap, the risk, who is responsible and when they will implement the gap. As a result, this document is key for keeping companies on track towards full compliance and sharing the status of their system as it pertains to their gaps with their interested parties

In Depth Definition and Purpose

At its core, a POAM identifies areas where an organization falls short of security requirements and lays out a concrete, actionable plan to reach compliance. It's a living document that not only specifies what actions are needed but also prioritizes them based on risk assessment, assigns responsibility, and sets timelines for resolution.

As defined by the National Institute of Standards and Technology:

A document for a system that “identifies tasks needing to be accomplished. It details resources required to accomplish the elements of the plan, any milestones in meeting the tasks, and scheduled completion dates for the milestones.
