CVE REMEDIATION + HARDENING PLAN:

IMMEDIATE (Today):
☐ Dependency: Log4j 2.14.1 → CVE-2021-44228 (RCE)
☐ Current version: 2.14.1 (VULNERABLE)
☐ Safe versions: 2.16.0+ or 2.17.0+ (with fixes)
☐ Action: Bump to 2.17.1 + test in staging

WHILE PATCHING (2-4 hours, parallel):
☐ Add WAF rule: Block JNDI strings in HTTP headers
☐ Block outbound LDAP on prod (remove if unused)
☐ Rotate all service credentials (potential compromise)
☐ Review CloudTrail logs for suspicious JNDI lookups (last 48h)

COMPLIANCE CHECKLIST:

SOC 2 Type II:
☐ Vulnerability severity tracked + remediation SLA (Critical = 24h)
☐ Patch deployed to staging → validated → prod deployment logged
☐ Change approval documented (emergency change log)

PCI-DSS v3.2.1:
☐ No delay allowed; Critical CVE requires same-day patch assessment
☐ Anti-malware signature updated (Log4j JNDI known signatures)

HIPAA (if applicable):
☐ Risk analysis documented (impact to PHI systems?)
☐ Remediation timeline approved

FULL HARDENING (Next 48h):
• SCA scan: Run toolchain on all dependencies (find 4+ other outdated packages)
• Secrets scan: Ensure no embedded creds in updated code
• Staging deployment: Run full regression (2-3h)
• Prod rollout: Blue-green deploy, monitor error rate 30m post-deploy
• Communication: Notify 3 customers of patch + zero-impact claim

WEEK 2 FOLLOWUP:
→ Automate dependency updates (weekly scanning)
→ Enforce max 30-day patch SLA in CI/CD
