Of the ensuing potential inputs to the Authorization package, one is not a living document. Which one? Response:

Supporting assessment documents, such as vulnerability scan results, audit logs, interview notes, or configuration snapshots, are artifacts collected during a specific assessment period. These documents represent a point-in-time record or evidence and are typically archived rather than continuously updated throughout the system's lifecycle, making them non-living documents.

Plans of Actions and Milestones (POA&Ms) are living documents that track deficiencies and their remediation, requiring continuous updates until all items are addressed.

Security and Privacy Assessment Reports are typically point-in-time snapshots of findings from an assessment, but 'supporting assessment documents' refers to the raw, underlying evidence which is even more definitively static.

A Security and Privacy Plan is a living document that outlines the system's security controls and is regularly reviewed and updated to reflect changes in the system, environment, or threat landscape.
