You are in the process of recovering from an incident where a web server and database server were severely compromised due to a lack of patching. Both servers have been rebuilt and fully patched…

The root cause of the compromise was a lack of patching, so the most critical post-recovery action is to formally recommend that business owners implement and maintain a regular patch management program. This aligns with the post-incident activity and lessons-learned phase described in NIST SP 800-61, which emphasizes identifying and communicating corrective actions to prevent recurrence. Documenting and delivering this recommendation directly addresses the vulnerability that led to the incident.

Having business owners test systems is important before returning to production, but it does not address the root cause or prevent a future incident.

Telling business owners all needed functionality is present is presumptuous and bypasses the stakeholder validation step they are responsible for performing.

Asking when to put systems back into production skips the critical steps of stakeholder testing and root-cause recommendations that must come first.

Telling business owners when you will put systems back into production bypasses stakeholder input and the required functional testing and validation steps.
