The Security Finding

Billing-export S3 bucket public-read ACL detected by CONDUIT scan — monthly bills with customer PII/location data were reachable unauthenticated. FCC CPNI §222 breach condition.

ITIL Change Management Fields

Justification

High: Billing-export S3 bucket public-read ACL detected by CONDUIT scan — monthly bills with customer PII/location data were reachable unauthenticated. FCC CPNI §222 breach condition.

Implementation Plan

1. Pre-change snapshot captured by TITAN (auto-rollback available).
2. Execute fix command:
   aws s3api put-public-access-block --bucket s3-telco-billing-exports --public-access-block-configuration BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true && aws s3api put-bucket-acl --bucket s3-telco-billing-exports --acl private
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 (s3-telco-billing-exports).
Blast radius: change is idempotent; pre-change snapshot captured by TITAN; auto-rollback available if rescan fails.
Finding detail: Billing-export S3 bucket public-read ACL detected by CONDUIT scan — monthly bills with customer PII/location data were reachable unauthenticated. FCC CPNI §222 breach condition.

Backout / Rollback Plan

1. TITAN auto-captured snapshot of s3-telco-billing-exports before change (baseline: titan-telecom-demo-20260422T201925Z).
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 s3-telco-billing-exports 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.

Recommended Fix

aws s3api put-public-access-block --bucket s3-telco-billing-exports --public-access-block-configuration BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true && aws s3api put-bucket-acl --bucket s3-telco-billing-exports --acl private
