The Security Finding

S3 bucket 's3-titan-customer-exports' has publicly accessible objects via BlockPublicAcls=false — exports of customer PII are exposed.

ITIL Change Management Fields

Justification

S3 bucket 's3-titan-customer-exports' has publicly accessible objects via BlockPublicAcls=false — exports of customer PII are exposed.

Implementation Plan

1. Pre-change snapshot captured by TITAN (auto-rollback available).
2. Execute fix command:
   aws s3api put-public-access-block --bucket s3-titan-customer-exports --public-access-block-configuration BlockPublicAcls=true,BlockPublicPolicy=true,IgnorePublicAcls=true,RestrictPublicBuckets=true
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: HIGH business risk — active exposure; fix required immediately.
Business impact if unremediated: Potential data exfil, privilege escalation, or compliance breach.
Scope: single resource (s3-titan-customer-exports).
Blast radius: change is idempotent; pre-change snapshot captured by TITAN; auto-rollback available if rescan fails.
Finding detail: S3 bucket 's3-titan-customer-exports' has publicly accessible objects via BlockPublicAcls=false — exports of customer PII are exposed.

Backout / Rollback Plan

1. TITAN auto-captured snapshot of s3-titan-customer-exports before change (baseline: titan-live-demo-20260421T213642Z).
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-titan-customer-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-titan-customer-exports --public-access-block-configuration BlockPublicAcls=true,BlockPublicPolicy=true,IgnorePublicAcls=true,RestrictPublicBuckets=true
