The Security Finding

Public DNS zone 'titan-demo-1896.local' was created without DNSSEC signing. DNS queries for this zone can be spoofed. CIS_AZURE_6.8.

ITIL Change Management Fields

Justification

Severity assessment: LOW — hygiene/best-practice drift; low business risk if deferred by one cycle.
Regulatory driver: CIS obligation.
Risk if deferred: Per industry telemetry, mean time to exploit a publicly-reachable misconfiguration of this class is measured in hours. Delaying this change extends exposure window and increases breach cost per IBM Cost of a Data Breach Report (avg $4.45M per incident).

Detected by: TITAN AI agent unknown (scan titan-3cloud-20260421T224916Z).
Finding: Public DNS zone 'titan-demo-1896.local' was created without DNSSEC signing. DNS queries for this zone can be spoofed. CIS_AZURE_6.8.

Implementation Plan

1. PRE-CHANGE VERIFICATION (5 min)
   - Confirm TITAN pre-scan snapshot captured; snapshot ID in work notes.
   - Confirm no blocking dependencies (check 'Affected CIs' below).
   - Announce change start in #ops-change Slack channel.

2. APPLY FIX (primary command, auto-generated by TITAN):
   Enable DNSSEC signing on zone (Azure Preview feature) OR consider using Azure Private DNS if zone is internal-only.

3. POST-CHANGE VERIFICATION (5 min)
   - Re-run TITAN targeted scan on the affected resource.
   - Confirm finding cleared (scan returns 0 matches for this finding_id).
   - Smoke-test dependent applications (see Test plan).

4. CLOSE
   - Update ticket state to Review -> Closed.
   - Attach scan-diff evidence (pre vs post).
   - If verification fails at step 3, execute Backout plan immediately.

Risk & Impact Analysis

Change risk level: LOW (routine hardening)

Blast radius: The change is scoped to a single cloud resource (Public DNS zone 'titan-demo-1896.local' was created without DNSSEC signing. DNS ...). Downstream dependencies (if any) are listed under 'Affected CIs'.

Minimal blast radius. Safe to batch with other low-risk changes.

Worst-case failure mode: Change is rejected by the cloud API (network partition or permission drift). Impact: no state change on target resource; Backout plan is a no-op. Time to detect: immediate (non-zero exit code from fix command).

Residual risk after successful fix: zero — the finding no longer exists. TITAN verifies this via post-change scan (see Implementation plan step 3).

Backout / Rollback Plan

If post-change verification fails or the fix causes a service disruption:

1. IMMEDIATE: Revert the resource to its pre-change state using the TITAN pre-scan snapshot (snapshot ID recorded in work notes at scan time).
2. Azure:  az <resource-type> update ... (inverse of the apply command) OR az deployment group create --template-uri <pre-change ARM URI>
3. AWS:    aws <service> ... (restore from snapshot or inverse IAM policy)
4. GCP:    gcloud <service> ... update --rollback
5. Confirm rollback succeeded by re-running TITAN scan — the original finding should reappear (confirming the state was fully reverted).
6. Document the failure mode in 'Close notes' for the post-incident review.
7. Re-open this change with 'Rejected' disposition and spawn a parent Problem ticket for root-cause analysis.

Test Plan

Acceptance criteria (must all PASS to close this change):

[ ] TITAN targeted re-scan of Public DNS zone 'titan-demo-1896.local' was created without ... returns ZERO matches for this finding_id.
[ ] Resource remains in provisioning_state=Succeeded (Azure) / available (AWS) / RUNNING (GCP) immediately after change.
[ ] Dependent applications pass smoke tests (HTTP 200 on health endpoints, auth still works for service accounts, DB connection-strings unchanged).
[ ] No new alerts raised in Azure Monitor / CloudWatch / Cloud Monitoring in the 30 minutes following the change.
[ ] Audit chain entry written: agent.change.applied event with pre/post hashes.

Any FAIL triggers the Backout plan above. Evidence attached to 'Closure Information' tab.

Recommended Fix

Enable DNSSEC signing on zone (Azure Preview feature) OR consider using Azure Private DNS if zone is internal-only.
