Security Checklist for AI-Generated Apps: Auth, RBAC, Payments
AI SaaS builder teams move fast, but production trust moves slower. Whether you ship with an application templates library or a restaurant ordering app builder AI, use this checklist to ship secure by default without slowing delivery.
Auth and Session Hardening
- Adopt OIDC with PKCE; require MFA or passkeys for all privileged roles.
- Use short-lived access tokens, rotating refresh tokens, and server-side session stores.
- Pin JWT iss/aud, enforce exp/nbf, and implement token revocation lists.
- Bind sessions to device + IP risk scoring; enable step-up auth for sensitive actions.
- Set secure, HttpOnly, SameSite=strict cookies; force TLS, HSTS, and CSP.
RBAC and Tenant Isolation
- Model roles and permissions explicitly; default to least privilege and deny-by-default.
- Evaluate authorization server-side, not in the client or the LLM layer.
- Enforce row-level security and per-tenant encryption keys; never rely on client-supplied tenant IDs.
- Manage policies as code (e.g., OPA/Rego); require code review and CI tests for changes.
- Provide break-glass roles with time-bound access and complete audit trails.
Payments and PII Controls
- Keep PCI scope small: use hosted fields/checkout; never store raw PAN or CVV.
- Verify webhook signatures, use idempotency keys, and seal retries with exponential backoff.
- Encrypt PII at rest; tokenize customer identifiers across services.
- Support SCA/3DS, prevent double charges, and log refund/void chains with actor identity.
- Normalize currency/precision; block mixed-currency cart exploits.
AI-Specific Threats
- Disable prompt-driven role escalation: allowlist tools/functions and validate arguments.
- Sanitize user inputs and retrieved context; strip secrets and access tokens from prompts.
- Constrain outputs with schemas and policy validators; quarantine unsafe content.
- Isolate embeddings per tenant; encrypt vector stores and control cross-tenant searches.
Supply Chain and Templates
- Vet application templates with SBOMs, pinned versions, and provenance (SLSA/COSIGN).
- Run SAST/DAST, dependency audits, and IaC scanning on every template merge.
- Harden containers (distroless, non-root, read-only FS) and sign images.
Observability and Response
- Emit structured, privacy-aware audit logs for auth, RBAC decisions, payments, and AI tool calls.
- Detect anomalies: sudden role grants, payment spikes, vector-store exfil attempts.
- Maintain runbooks, RTO/RPO, and practice incident sims with canary tokens and chaos drills.
Example Snapshots
- Restaurant ordering app builder AI: managers can refund only within their venue and up to $100; step-up auth for higher refunds; couriers see delivery addresses but not full payment details.
- Enterprise CRM template: AI note-summaries cannot fetch deals from other tenants; exporting contacts requires finance or legal approval via workflow with signed webhooks.
Quick API Checklist
- Rate limit per user and per tenant; apply circuit breakers and surge queues.
- Require HMAC-signed webhooks, TLS 1.2+, and automated certificate rotation.
- Store secrets in a vault; rotate on every breach suspicion; never log secrets.
- Adopt zero-trust between services; mutual TLS and policy-based access.
Bake these controls into your scaffolding so every new service and template inherits security. That's how an AI SaaS builder ships fast, stays compliant, and earns durable customer trust.
