# Workflows - Vulnerability Exception Tracking
|
|
|
|
## Workflow 1: Exception Request and Approval
|
|
|
|
### Steps
|
|
1. Asset owner identifies vulnerability that cannot be remediated within SLA
|
|
2. Owner submits exception request with justification and compensating controls
|
|
3. System validates request completeness and category-specific fields
|
|
4. System routes request to appropriate approver based on severity and category
|
|
5. Approver reviews justification and compensating controls
|
|
6. Approver approves, rejects, or requests additional information
|
|
7. If approved, exception is recorded with expiration date
|
|
8. Vulnerability status updated in scanner/DefectDojo to "exception_approved"
|
|
9. Audit log entry created with full approval chain
|
|
|
|
## Workflow 2: Daily Expiration Check
|
|
|
|
### Steps
|
|
1. Cron job queries all active exceptions with expires_at <= today + 14 days
|
|
2. For exceptions expiring within 14 days: send renewal reminder to requestor
|
|
3. For exceptions expiring within 7 days: send urgency reminder with escalation
|
|
4. For expired exceptions: update status to "expired", revert vulnerability to "open"
|
|
5. Send expiration notification to asset owner and security team
|
|
6. Regenerate SLA tracking to include re-opened findings
|
|
|
|
## Workflow 3: Quarterly Exception Review
|
|
|
|
### Steps
|
|
1. Generate report of all active exceptions grouped by category and severity
|
|
2. For each exception, verify compensating controls are still in place
|
|
3. Review if vendor patch has become available for "no_fix" exceptions
|
|
4. Re-assess risk rating based on current threat landscape
|
|
5. Escalate exceptions with changed risk profiles for re-approval
|
|
6. Update exception records with review notes and new risk ratings
|
|
7. Submit quarterly report to security governance committee
|
|
|
|
## Workflow 4: Compensating Control Validation
|
|
|
|
### Steps
|
|
1. For each active exception, extract listed compensating controls
|
|
2. Validate each control is still operational:
|
|
- WAF rules: Query WAF API for rule status
|
|
- Network segmentation: Verify firewall rules
|
|
- Monitoring alerts: Confirm SIEM rules are active and triggering
|
|
3. Flag exceptions where compensating controls have degraded
|
|
4. Notify exception requestor and security team of control failures
|
|
5. If controls cannot be restored within 48 hours, revoke exception
|
