GuardDuty findings for a utilities account pile up in Security Hub…

Question

GuardDuty findings for a utilities account pile up in Security Hub while MTTR stays high because responders lack a standard triage path. Which improvement should the architects prioritize?

Accepted Answer

Publish triage and remediation playbooks (runbooks/Automation) driven from Security Hub findings so high-severity GuardDuty alerts follow a consistent response path. — Findings without a playbook are smoke alarms with no fire drill. Security Hub gathers the smoke; runbooks tell who opens which door next. Shrink MTTR by rehearsing the path, not by silencing the detectors.

Answer

Mute all GuardDuty findings permanently to reduce alert fatigue.

Answer

Delete the Security Hub aggregator so each account must be reviewed in isolation forever.

Answer

Forward every finding to a public Slack channel without severity filtering or ownership.
