10/10.🎁 Bonus: Tools for Secure APIs.🔐 Auth – Keycloak, Auth0, OAuth 2.0.🚦 Rate Limits – Kong, NGINX, AWS API Gateway.📊 Logging – ELK Stack, Datadog.🧪 Validation – Joi, Zod, Hibernate Validator.

9/10.🛡️ 8. Monitor & Audit Everything.• Log access, errors, and suspicious behavior.• Use SIEM, alerts, anomaly detection.• Visibility = faster incident response.

8/10.📜 7. Secure Your Endpoints.• Set strict CORS policies.• Disable unused HTTP methods (PUT, DELETE, etc.).• Lock down internal APIs.

7/10.🔍 6. Validate Tokens & Sessions.For every JWT:.• Check signature.• Validate expiration.• Confirm issuer & audience.• Rotate keys and monitor abuse.

6/10.🧼 5. Hide Sensitive Data in Responses.• Don’t expose stack traces, internal IDs, or debug logs.• Show clean, minimal responses.• Avoid giving attackers clues.

5/10.🚧 4. Apply Rate Limiting & Throttling.No limits? Say hello to:.• Brute-force attacks.• DDoS.• Abuse from bots.✅ Add limits via API Gateway or reverse proxy.

4/10.🔒 3. Always Use HTTPS.Still using HTTP? 🚨.• Use TLS (HTTPS) for all requests.• Prevent MITM & data leaks.• No excuses in 2025.

3/10.🔐 2. Use Authentication & Authorization.• Use JWT or OAuth 2.0.• Enforce RBAC or scopes.• Ensure only the right users access the right resources

2/10.🚫 1. Never Trust User Input.Your frontend is not a firewall. • Validate, sanitize, escape.• Defend against injection attacks.• Never assume client-side data is safe

🧵 1/10.🚨 Building APIs? Then you must know these 8 security best practices. A thread 🧵.APIs are powerful — but insecure ones are a hacker’s dream. Here are 8 unskippable security controls you must follow. Let’s break them down 👇

8/8 🙌 Let’s Connect. Are you also using JUnit or Mockito in your backend projects?.Drop your experience below 👇.Let’s learn from each other 💬.#BackendDeveloper #JavaDeveloper #UnitTesting #CodeQuality #DevLife.

7/8 🧰 Tools I Used. #Java | #SpringBoot.#JUnit5 | #Mockito.#CleanCode | #TestingMindset.If you're building backend apps — add these to your stack. It pays off.

6/8 💬 Reminder for Every Java Dev. “A good coder doesn’t just write code that works. They write code that’s tested. Let your code prove itself.”.

5/8 🧠 Personal Growth. This shifted my mindset from "just build it" → to. "Build it. Test it. Own the quality.".Felt more like a real developer, not just a coder.

4/8 🔍 From Simple to Complex. Once I got comfortable, I applied these techniques to more complex backend projects — where testing impacts:. 🔹Stability 🔒.🔹Debugging speed ⚡.🔹Confidence in deployment 🚀

3/8 📘 What I Learned. 🔹 JUnit = clean, structured unit tests for Java methods.🔹 Mockito = mocking dependencies to isolate logic.🔹 Early testing leads to better design and fewer bugs

2/8 🛠️ Took Action. I picked up my old 🗂️ ToDoList project and refactored it—not to add new features, but to write clean & testable code. What I integrated:.✅ JUnit 5 for unit testing.🧪 Mockito for mocking services.🔍 Tests for edge cases, error flows, and logic branches

🧵 1/8 💡 Java Dev Tip That Leveled Up My Code Quality. A while back during an interview, I got this golden advice:. "Get strong with JUnit & Mockito for developer-level testing.". That one line reshaped how I code. Here’s what I did 🧪👇
