Protect access first
Use an account you can recover and keep recovery options current. Give each person individual access where supported. Review permissions when responsibilities change. Keep administrative interfaces separate from public application routes, and maintain an update and recovery process.
Handle data with a purpose
Collect only what a feature needs and decide how long it should remain. Keep secrets out of source control, browser code, diagnostic URLs and public logs. Use synthetic data in shared debugging examples. A useful log describes an event without copying an entire request.
Prepare for recovery
Track dependency updates and test changes before publishing them. Keep backups separate from the data they protect and verify restoration. Write down who can make incident changes, how to preserve evidence and how to communicate current impact. Practice on an isolated test environment.
