Significant Change Requests and Maintaining Your ATO
A FedRAMP authorization covers your system as it was assessed. When you change that system significantly, you may need a Significant Change Request (SCR) to keep the authorization intact.
What counts as significant
- New or changed external services, regions, or major architectural components.
- Changes that alter the authorization boundary or data flows.
- New features that introduce new data types or change the impact categorization.
How the SCR process works
You notify your authorizing official before the change, describe its security impact, and — depending on scope — have a 3PAO assess the affected controls. The agency reviews and approves before (or shortly around) the change goes live, and the package is updated to reflect the new state.
Staying authorized while you ship
The trap is treating SCRs as an afterthought. Build a lightweight change-impact triage into your release process: for each change, decide whether it is routine, a configuration change, or a significant change, and route it accordingly. That keeps engineering moving without putting the ATO at risk.
