Incident Response Flow
Understanding the Concept
A DLP incident occurs when policy triggers a significant match - typically a high-severity alert. Incident response involves investigation, containment, remediation, and lessons learned.
Investigation uses Activity Explorer to trace the incident: what data, what user, what action, what time. Context from related activities helps understand intent.
Response may include: revoking access, contacting the user, HR involvement, legal notification, or regulatory reporting. Documentation throughout is critical.
Key Points
- Detection: Alert received from DLP policy
- Triage: Assess severity and business impact
- Investigation: Use Activity Explorer to understand scope
- Containment: Stop ongoing data loss if active
- Remediation: Cleanup and policy adjustment
- Documentation: Record for audit and improvement
Incident Response Workflow
Alert Received
DLP alert triggers investigation
Initial Triage
Assess severity, assign responder
Investigation
Activity Explorer, interviews, evidence collection
Containment
Stop ongoing loss, preserve evidence
Remediation
Delete/recall data, revoke access
Lessons Learned
Policy tuning, training, process improvement
Why This Matters in Real Organizations
DLP without incident response is just monitoring. Effective response prevents data loss from becoming data breach, maintains regulatory compliance, and improves the DLP program over time.
