# Workflows - AWS GuardDuty Findings Automation ## Automated Response Workflow ``` 1. GuardDuty detects threat → Generates finding 2. EventBridge receives finding event 3. EventBridge routes to Lambda based on severity/type 4. Lambda executes automated response: - EC2: Quarantine instance, snapshot volumes - IAM: Deactivate keys, apply deny policy - S3: Block public access, enable versioning 5. SNS notifies security team 6. Finding synced to Security Hub 7. Analyst reviews and confirms actions ``` ## Triage Workflow ``` 1. HIGH (7-8.9): Immediate auto-response + page on-call 2. MEDIUM (4-6.9): Auto-notify + queue for review 3. LOW (1-3.9): Log and batch review weekly ```
