Overlays can be implemented as part of control tailoring after the completion of what process? Response:

Risk assessment is an ongoing process, but control selection and tailoring, including overlays, typically follow security categorization to establish the initial baseline.

Security categorization (e.g., FIPS 199) determines the impact level (low, moderate, high) of an information system, which then dictates the baseline set of security controls. Overlays are applied after this baseline is established to add specialized controls relevant to specific risk areas, technologies, or missions, tailoring the baseline to the system's unique context.

A Privacy Impact Assessment (PIA) identifies privacy risks but is not the preceding process for applying overlays during control selection and tailoring.

A Contingency Plan (CP) is developed to ensure system recovery, but its completion does not precede the application of overlays during control tailoring.
