From Cloud Incident to Detection in 24 Hours

How to turn a cloud breach report into actionable detections and guardrails in one workday.

Intake checklist

• What failed? Identity, network, storage, or app?
• Was there lateral movement? Which roles? Which regions?
• Logs available? IAM, VPC, load balancer, function/task logs.

24-hour response

• Hour 1–3: Contain credentials, rotate keys, disable suspicious roles.
• Hour 4–6: Reconstruct timeline; map attacker paths; snapshot evidence.
• Hour 7–12: Draft detections: impossible travel, unusual role use, public bucket creation, permissive firewall changes, mass decrypts.
• Hour 13–18: Add guardrails: SCPs/Org Policies, service control baselines, least-privilege templates.
• Hour 19–24: Tabletop the new detections with the team; deploy to prod with alerts + runbooks.

Output format

• Detection rule, severity, sample log, suppression guidance.
• Guardrail change, owner, rollback plan.

Takeaway

Incidents are expensive—use each one to harden identity, logging, and change control immediately.
