ITIL Change Management Fields

Justification

High: Cross-account IAM role trust policy uses wildcard principal (*). Any AWS account can assume this role — critical lateral-movement risk for banking workloads. SOX ITGC and FFIEC violation.

Implementation Plan

1. Pre-change snapshot captured by TITAN (auto-rollback available).
2. Execute fix command:
   aws iam update-assume-role-policy --role-name banking-crossaccount --policy-document file://fixed-trust-policy.json
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 (iam-role-banking-crossaccount).
Blast radius: change is idempotent; pre-change snapshot captured by TITAN; auto-rollback available if rescan fails.
Finding detail: Cross-account IAM role trust policy uses wildcard principal (*). Any AWS account can assume this role — critical lateral-movement risk for banking workloads. SOX ITGC and FFIEC violation.

Backout / Rollback Plan

1. TITAN auto-captured snapshot of iam-role-banking-crossaccount 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 iam-role-banking-crossaccount 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.
