Cloud audit logging: what to log, retention, and alerting use cases (engineer-friendly, step-by-step)

  If you’re setting up cloud audit logging (AWS/Azure/GCP) and feel overwhelmed by what to log, how long to retain it, and when to alert, this engineer-friendly guide breaks it down step-by-step with practical use cases—so you can improve security and troubleshooting without drowning in noisy logs.

Cloud Audit Logging — what actually matters:

✅ What to log (must-have)

• IAM/auth changes, privileged actions, policy edits

• Network/security changes (SG/NACL/firewall, public exposure)

• Data access events (storage reads, DB admin actions)

• Kubernetes + workload changes (deployments, secrets, config)

✅ Retention (simple rule of thumb)

• Short-term “hot” logs for investigations + debugging

• Longer retention for compliance + incident timelines

• Archive strategy so costs don’t explode

✅ Alerting that’s useful (not noise)

• Root/admin activity, unusual geo/logins

• Permission escalations, key creation, MFA disabled

• Sudden spike in denied actions or data downloads

• Changes to logging itself (tampering / disable events)
