What document is necessary to outline corrective actions and ongoing monitoring of an information system?

The Plan of Actions and Milestones (POAM) is essential for outlining corrective actions and ongoing monitoring of an information system. This document serves as a comprehensive framework for identifying vulnerabilities within an information system and detailing the actions necessary to mitigate those risks effectively. It not only identifies specific weaknesses but also lists the milestones required to address these weaknesses, along with timelines and responsible parties for each task.

The POAM is an integral part of maintaining compliance and ensuring that systems remain secure over time by requiring continual reassessment and updates as conditions change. This proactive monitoring helps organizations manage their information security risk landscape effectively and assures stakeholders that they are taking appropriate measures to protect their data.
