Continuous compliance

Readiness decays when systems, vendors, people, contracts, or CUI flows change without corresponding updates to documentation and evidence.

Operating cadence

Review material changes

Review the scope and documentation when the organization adds a location, cloud service, network segment, acquisition, major vendor, contract, or new CUI workflow—or when a security incident changes the risk picture.

Run periodic checks

Set a risk-based cadence for access reviews, vulnerability and patch management, logging, incident-response exercises, backups, training, asset reconciliation, and evidence refresh.

Conduct an annual leadership review

Confirm that the SSP still matches the environment, open remediation work has accountable owners, required affirmations are supported, and responsible leaders understand the representation being made.

Prepare throughout the cycle

Do not wait for the next assessment window to rebuild evidence. Maintain the package as work occurs, test interview readiness, and resolve inconsistencies while the people who created them still remember why.

Change-control questions

For every material change, ask:

1. Does this change the CUI boundary?
2. Does it add an external service provider or security protection asset?
3. Which requirements, policies, diagrams, and evidence are affected?
4. Does the SSP need revision?
5. Who approves the new operating state?

Continuous compliance is routine operational discipline with an assessment trail—not a binder revisited every few years.
