Security Checklist for AI-Generated Apps: Auth, RBAC, Payments
AI code tools accelerate delivery, but security hardening for AI-built apps is never automatic. Whether you ship with a social network builder AI or a full-stack app generator, lock down the foundations before scaling users or revenue.
Authentication: prove identity, not intent
- Enforce passwordless + MFA (WebAuthn or TOTP). Make MFA mandatory for admins and payment actors.
- Use short-lived sessions; rotate refresh tokens; set Secure, HttpOnly, and SameSite=strict on cookies.
- Prefer OAuth2/OIDC with PKCE; minimize scopes; bind tokens to client + IP when feasible.
- Centralize secrets with KMS; rotate signing keys; pin JWT alg to RS256/EdDSA; reject none.
- Rate-limit login, signup, and recovery; deploy bot detection on public endpoints.
RBAC and data boundaries
- Model permissions as policies, not booleans. Use least privilege and deny-by-default.
- Apply row-level security in the database; never trust client-side identifiers for access control.
- Derive authorization from server claims; do not accept ownerId from the request body.
- Separate admin plane from user plane; require step-up auth and dual approval for destructive actions.
- For generated messaging feeds, enforce "can-view" via follower graph checks before query execution.
Payments and entitlements
- Never touch raw card data; use Stripe/Adyen elements; store only tokens.
- Validate webhooks with signatures, timestamps, and replay windows; use idempotency keys on writes.
- Build an entitlements service that maps plan → capabilities → RBAC roles; audit every grant.
- Throttle trial creation and coupon redemption; require verified email or card to reduce promo abuse.
AI-specific pitfalls you'll miss if you trust the scaffold
- Codegen often ships debug routes; disable in prod and gate behind allowlists in staging.
- Templates pull many transient dependencies; pin versions, run SCA/SAST, and verify SBOMs.
- If your app embeds LLM features, guard prompts/outputs to prevent data exfiltration; redact PII in logs.
- Generate API clients with strict schemas; reject unknown fields to block mass-assignment.
Operational controls that stick
- Automate baseline hardening (CIS) and IaC validation; enforce least-privilege IAM.
- Threat model per feature using STRIDE; track mitigations next to user stories.
- Emit structured audit logs for auth, RBAC decisions, and payment state changes; alert on anomalies.
- Encrypt backups; test restores monthly; add WAF, DDoS protection, and per-route rate limits.
Quick audit before launch
- No admin actions without MFA and logs.
- Every query checked by policy or RLS.
- Webhooks verified and idempotent.
- Secrets rotated; debug off; dependencies pinned.
- Entitlements tied to RBAC, not client flags.
Treat generators as interns: fast, helpful, and unsafely optimistic. Bake these controls into your templates, CI checks, and platform defaults. Enterprise buyers will ask for proofs-policies, logs, and tests-not promises. When a social network builder AI or full-stack app generator ships features, your checklist ensures the release is truly production-grade. Across teams, automate guardrails relentlessly.
