Security checklist for AI-generated apps: auth, RBAC, payments
AI app builders accelerate delivery, but security debt scales faster today. Use this concise checklist to harden AI-generated applications, including survey app builder AI projects and products that rely on subscription billing integration AI safely.
Identity and authentication
- Use OIDC with OAuth 2.1 and PKCE; disable the implicit flow; prefer short-lived tokens plus rotating refresh tokens.
- Sign JWTs with asymmetric keys (RS256/ES256), include aud, iss, sub, exp, and jti; enforce clock skew and token revocation lists.
- Require MFA for risky actions; support SSO (SAML/SCIM) for enterprise tenants; rate-limit login and magic-link endpoints.
- Separate user sessions from service credentials; for service-to-service calls, use mTLS or workload identity (SPIFFE/OIDC).
- Store secrets in a vault; rotate keys quarterly; enforce least privilege on CI and deployment robots.
- Verify email/phone before granting access; throttle invites; prevent user enumeration with uniform error messages.
Authorization, RBAC, and data isolation
- Model roles explicitly (e.g., Owner, Admin, Analyst, Author, Reader); map API scopes to each capability.
- Implement tenant isolation with org_id on every table; enforce row-level security and schema-level policies in the database.
- Adopt ABAC for fine control (department, region, data sensitivity); deny by default; test negative cases.
- Create tamper-evident audit logs for authZ decisions and admin changes; stream to a separate account.
- Use just-in-time elevation, time-boxed; define break-glass with approvals and post-incident reviews.
- For LLM tools, gate actions by role and scope; sanitize prompts; strip secrets; validate tool outputs.
Payments and subscription security
- Minimize PCI scope: use hosted payments, tokenization, and client-side elements; complete the right SAQ.
- Verify webhooks with signatures and timestamps; enforce idempotency keys; store minimal PII.
- Harden dunning and proration logic; protect metering endpoints with auth and replay guards.
- Test SCA, off-session charges, retries, and card updates; block business-logic abuse via rate limits.
- For subscription billing integration AI workflows, review generated logic for tax, refunds, and plan changes.
AI data, privacy, and integrity
- Classify data; encrypt sensitive fields at rest and in transit; use field-level encryption for survey responses.
- Redact PII before sending prompts; apply DLP and allowlists; log prompts with secrets removed.
- Defend against prompt injection: ground responses, restrict tool schemas, and add output validation and policy checks.
- Constrain models with least-privilege connectors; use signed, expiring URLs for object access.
Validation scenarios to run before launch
Assemble red-team scripts for an enterprise buyer: cross-tenant data read, privilege escalation from Analyst to Admin, webhook replay, and survey export exfiltration. For a survey app builder AI, verify that guest links cannot access private responses and that anonymization holds under reidentification attempts. For an AI app builder delivering payments, simulate plan downgrades, expired cards, and malicious proration spikes. Ship only after every scenario is reproducible and green in CI.
