CISO THREAT MODEL — USER DATA EXPORT FEATURE:
FEATURE SCOPE: Authenticated users can export account data (profile, activity log, settings) as CSV or JSON. No third-party sharing.
THREAT ANALYSIS:
THREAT 1 — Unauthorized export (SEVERITY: High). Risk: User A exports User B's data if user ID validation missing. MITIGATION: Verify export request matches authenticated user ID. Add rate limiting (5 exports per day per user). Implement immediately.
THREAT 2 — Data in transit (SEVERITY: Medium). Risk: CSV sent over HTTP (plaintext). MITIGATION: HTTPS only. Add Content-Disposition header (attachment mode). Implement immediately.
THREAT 3 — Audit trail gap (SEVERITY: Medium). Risk: No record of who exported what. Compliance issue for SOC 2. MITIGATION: Log every export (user ID, timestamp, row count, IP address) to immutable audit table. Implement before launch.
THREAT 4 — Sensitive data leakage (SEVERITY: Medium). Risk: Passwords, API keys appear in exported activity log. MITIGATION: Scan export before delivery. Redact sensitive patterns (password, token, api_key). Implement before launch.
COMPLIANCE REQUIREMENTS:
GDPR: Right to data portability satisfied. Recommend DPIA (data protection impact assessment) documentation.
CCPA: Consumer right-to-know satisfied. Disclose data sale status in privacy policy update.
SOC 2: Audit logging required. Implement threat 3 mitigation.
SIGN-OFF GATE: Security team (required). Legal team (required). Privacy team (required). Launch greenlit only after all three approvals.
