Use this checklist in the right order
The most common mistake is treating the checklist like a shopping list of controls. Start with scope, then move into control validation, documentation, remediation, and sustained maintenance.
Readiness checklist
- Confirm whether the company handles FCI, CUI, or both.
- Identify where CUI enters, resides, moves, and leaves the environment.
- Create or refresh the asset inventory and the network / data-flow diagrams.
- Define the assessment boundary and identify systems providing security protection.
- Review identity, access, endpoint, logging, encryption, backup, and incident response practices.
- Collect existing policies, procedures, diagrams, inventories, and implementation records.
- Build the remediation roadmap.
- Prepare SSP, POA&M, and supporting evidence structure.
- Plan for the operating model after the initial readiness sprint.
