What type of documents must the system owner or unit ISSM upload?

The system owner or unit Information System Security Manager (ISSM) must upload current audit and Corrective Action Strategy (CAS) documentation and plugins. This requirement is essential as it directly relates to the security posture of the system. Current audit documentation provides evidence that the system has been thoroughly assessed for vulnerabilities and compliance with applicable security standards. The Corrective Action Strategy further outlines how identified issues are being addressed to ensure ongoing compliance and security.

This focus on current documentation reflects a proactive approach to risk management and maintaining system integrity, which is critical in a continually evolving cybersecurity landscape. By keeping audit and CAS documents current, the system owner ensures that all stakeholders have access to the most relevant information related to the system's security status, facilitating informed decision-making and response planning.

In contrast, annual budget reports, all user agreements, and external compliance documents may contribute to broader organizational activities but do not specifically address the immediate security management and oversight responsibilities that the ISSM must maintain to protect the system effectively.
