Just saw someone on X whose product got attacked while building in public using Cursor AI. Don’t blindly trust AI, stay mindful of security!
Here are some essential security measures to keep your app safe:
🛡 Frontend Security:
✅ Escape & sanitize user input to prevent XSS
✅ Use CSRF tokens to stop unauthorized requests
✅ Store JWTs in HttpOnly Secure Cookies, NOT LocalStorage
✅ Enforce HTTPS + Content Security Policy (CSP)
✅ Block clickjacking with X-Frame-Options: DENY
🛡 Backend Security:
✅ Validate ALL user input to prevent SQL/NoSQL Injection
✅ Implement JWT/OAuth + Role-Based Access Control (RBAC)
✅ Set up Rate Limiting & DDoS protection
✅ Monitor & log anomalies (Datadog, Prometheus, etc.)
✅ Secure API responses. No sensitive data in error messages
🛡 Database Security:
✅ Use Prepared Statements (NEVER concatenate SQL)
✅ Encrypt sensitive data at rest & in transit (AES-256, SSL/TLS)
✅ Regular backups & access control (least privilege principle)
✅ Enable audit logs to track suspicious activity
📱 Mobile App Security
✅ Never store API keys or secrets inside the app (use backend storage)
✅ Use Secure Enclaves & Keychain (iOS) / Keystore (Android) for sensitive data
✅ Encrypt local storage (AES-256) for user data & tokens
✅ Code obfuscation to prevent reverse engineering (ProGuard, R8, Obfuscator-LLVM)
✅ Detect rooted/jailbroken devices to prevent tampering
✅ Implement biometric authentication (Face ID, Touch ID) for sensitive actions
✅ Always verify API responses & implement certificate pinning
Building in public is great, but don’t let security be an afterthought! Stay safe out there.
PS: That's why I use a Backend with NestJS to handle all logic related to AI API keys and usage, while only performing basic CRUD operations with the Supabase Client.

@nixflixx_ I LOVE the feeling of physical books, but the Kindle has been a game changer for me. Books are easily accessible, and adjusting the screen settings makes long reading sessions easier on my eyes.

Listen in on the latest Twitter AMA between @IndiGG_DAO x @playrooniverse, a web3 game where cute animals kill each other in a battleroyal setting ~ it's also a mobile game. 😬
