Security Breach Investigation

Scenario

After a security breach, the organization needs to investigate how the incident occurred and confirm whether a Data Security detection reflects a genuine, wider security incident — not just a storage-layer anomaly.

Implementation

Data Forensics logs all data operations and provides search capabilities across user and file activity. Treat Data Security as one detection domain within a broader incident response (IR) process: combine its storage-layer alerts with investigation from your endpoint protection and Identity and Access Governance (IAG) tools before deciding on lockout, recovery, or closure.

Incident Response Workflow

Storage-layer detection is a symptom — the entry point of a breach is usually the endpoint, so treat this workflow as one part of a larger, multi-domain investigation rather than a standalone verdict.

Step 1 — Open an investigation

Create an investigation or incident in your SOC tooling for the reported detection, using the affected username, client IP, and affected shares as the starting context.

Step 2 — Client IP investigation (endpoint)

Look up the client IP in your endpoint management system and review any threat signals already logged for that host. If your endpoint software supports it, launch a deep scan and add any resulting artifacts to the SOC investigation.

Step 3 — Username investigation (IAG)

Check the affected username in your Identity and Access Governance (IAG) platform for anomalous login behavior that could indicate account compromise. Add any findings to the SOC investigation.

Step 4 — Storage-layer decision

Once you've gathered endpoint and IAG context, decide whether the storage-layer detection needs further action:

Confirm whether the affected user is already locked out, and lock the user out if the behavior warrants it.
Confirm the affected shares in the event detail and add them to the SOC investigation's artifact list.
Verify that snapshots were taken for the active event.
Check whether other active events exist for the same user or cluster — additional active events are a further indicator of possible compromise and should go through the same multi-domain review.

Use the combined endpoint, IAG, and storage-layer context to reach a final determination:

False positive — unlock the user and close the event.
Confirmed breach — continue to the forensics phase below.

Step 5 — Forensics phase (confirmed breach only)

Only begin this phase after multi-domain context indicates a genuine breach. Validate the endpoint first — it's the entry point of the breach, and the storage-layer detection is a downstream symptom.

Run a historical user search for each affected username using Data Forensics. Review the user's file access patterns over that window for signs of bulk rename, bulk delete, or bulk read operations — indicators of data exfiltration rather than a single isolated event.

caution

Storage-layer forensics is one component of a larger incident response process. Detection and response at the storage layer should not be the sole basis for concluding whether a breach or cyber incident occurred.

Outcome

Security analysts combine storage-layer detection with endpoint and IAG context to reach a confident determination of false positive versus confirmed breach, efficiently sift through logs to pinpoint root cause, and enact preventive measures to avert similar incidents in the future. In the event of a confirmed incident, the historical user search and full audit trail support forensic investigation and recovery decisions.
