The Security Finding

Security group sg-banking-webtier-prod allows 0.0.0.0/0 on port 3306 (MySQL) — production banking DB exposed to internet. PCI DSS 1.2.1 firewall/router configuration violation.

ITIL Change Management Fields

Justification

High: Security group sg-banking-webtier-prod allows 0.0.0.0/0 on port 3306 (MySQL) — production banking DB exposed to internet. PCI DSS 1.2.1 firewall/router configuration violation.

Implementation Plan

1. Pre-change snapshot captured by TITAN (auto-rollback available).
2. Execute fix command:
   aws ec2 revoke-security-group-ingress --group-id sg-0abc123 --protocol tcp --port 3306 --cidr 0.0.0.0/0
3. TITAN FORGE verifies the fix was applied.
4. Post-change rescan by TITAN SCOUT — finding must no longer appear.
5. Close ticket with Successful close_code.

Risk & Impact Analysis

Risk level: MEDIUM-HIGH risk — misconfiguration with realistic exploit path.
Business impact if unremediated: Increases attack surface; auditor finding likely.
Scope: single resource (sg-banking-webtier-prod).
Blast radius: change is idempotent; pre-change snapshot captured by TITAN; auto-rollback available if rescan fails.
Finding detail: Security group sg-banking-webtier-prod allows 0.0.0.0/0 on port 3306 (MySQL) — production banking DB exposed to internet. PCI DSS 1.2.1 firewall/router configuration violation.

Backout / Rollback Plan

1. TITAN auto-captured snapshot of sg-banking-webtier-prod before change (baseline: titan-banking-demo-20260422T201922Z).
2. If post-change rescan still shows the finding OR a new issue appears within 15 min:
   a. TITAN FORGE fires rollback automatically using stored snapshot.
   b. Incident reopens and escalates to on-call.
3. Manual rollback command path (human override) is documented in close notes.

Test Plan

1. TITAN SCOUT rescans sg-banking-webtier-prod immediately after FORGE applies the change.
2. PASS criteria: the specific finding no longer appears in SCOUT results.
3. PASS criteria: no new CRITICAL or HIGH findings introduced by the change.
4. Automated compliance check: HIPAA/PCI/SOC2 controls re-evaluated.
5. If any check fails, backout plan fires automatically.

AI Close Notes

TITAN CONDUIT opened this high network ticket and assigned it to the banking_compliance group for review. STATE: ASSIGNED — awaiting human action. Per TITAN AI policy, configuration changes are NEVER auto-applied and tickets are NEVER auto-closed by TITAN. The assigned group reviews the recommended fix, schedules an approved maintenance window, applies the fix manually, validates via SCOUT rescan, and closes this ticket themselves. TITAN documents and routes — the human owns the change from here.
