What document identifies existing risks, ongoing monitoring, corrective actions, and the current disposition of an information system?

The document that identifies existing risks, ongoing monitoring, corrective actions, and the current disposition of an information system is the Plan of Actions and Milestones, commonly referred to as the POAM. This document is crucial in risk management and cybersecurity, as it provides a structured approach to documenting known vulnerabilities and the strategies in place to mitigate them.

The POAM outlines specific actions that are planned or in progress to address identified security weaknesses. It gives stakeholders an understanding of the current status of the IT system's security posture, the effectiveness of any mitigating actions being taken, and the timeline for completing risk mitigation activities. This continuous monitoring and documentation help ensure that risks are managed effectively and that the information system remains secure over time.

In contrast, the Authorization to Operate (ATO), Certification, and Accreditation do not serve the specific purpose of tracking ongoing risks and their mitigations. The ATO is a formal declaration that an information system is approved to operate based on an acceptable level of risk. Certification generally refers to the process of verifying that a system meets certain standards, while accreditation is the formal acknowledgment that a system has been evaluated and is authorized to operate. Thus, while these terms are related to information system security, they do not encompass the comprehensive details of
