# 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
|
|
```
