Scenario
One alert still fires after updating an allowlist.
A SIEM allowlist is updated and one alert still fires because the source IP list keeps the old address

What to check first
- Identify the primary failure signal in the Incident Response scenario.

- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
