Security Is Your Responsibility

BaaS platforms handle infrastructure security, but application-level security is still on you.

The Checklist

1. Row-Level Security (RLS)

Ensure every table has proper RLS policies. Without them, any authenticated user can read all data.

2. API Key Exposure

Never expose service-role keys in client-side code. Use anon keys with RLS instead.

3. Input Validation

Validate all user inputs on both client and server side.

4. Authentication Flows

Test edge cases: expired tokens, concurrent sessions, password reset flows.

5. File Upload Security

Restrict file types, sizes, and scan for malware where possible.

6. Rate Limiting

Implement rate limiting on auth endpoints and API calls.

7. CORS Configuration

Restrict allowed origins to your actual domains.

8. Data Encryption

Ensure sensitive data is encrypted at rest and in transit.

9. Audit Logging

Track who accessed what and when.

10. Dependency Updates

Keep your BaaS SDK and all dependencies up to date.

Conclusion

Security isn’t a feature you add at the end — it’s a practice you maintain throughout development.
