3.12.2

Requirement

Develop and implement plans of action designed to correct deficiencies and reduce or eliminate vulnerabilities in organizational systems.

Discussion

The plan of action is a key document in the information security program. Organizations develop plans of action that describe how any unimplemented security requirements will be met and how any planned mitigations will be implemented. Organizations can document the system security plan and plan of action as separate or combined documents and in any chosen format. Federal agencies may consider the submitted system security plans and plans of action as critical inputs to an overall risk management decision to process, store, or transmit CUI on a system hosted by a nonfederal organization and whether it is advisable to pursue an agreement or contract with the nonfederal organization. [NIST CUI] provides supplemental material for Special Publication 800-171 including templates for plans of action.
