🔐 Secure Your APIs: JWT, Roles & Policies in ASP.NET Core

Engineer Security — Don’t Guess It.

🗝️ About This Course

Most developers can build APIs. Very few know how to secure them correctly.

This course is a complete, practical guide to securing RESTful APIs in ASP.NET Core, using real-world security patterns applied by professional backend teams.

You won’t learn random snippets. You’ll learn how security is designed, layered, and enforced.

You start with an insecure API and end with a production-ready system.

🔐 What Makes This Course Different?

🔹 Built around one real project (Student API)
🔹 Security added gradually, not all at once
🔹 Strong focus on why, not just how
🔹 Covers real vulnerabilities developers actually miss
🔹 No ASP.NET Identity complexity — pure understanding first

This course teaches security engineering, not framework tricks.

📖 What You Will Learn?

By the end of this course, you will be able to:

🔹 Implement JWT authentication correctly
🔹 Secure APIs using [Authorize], roles, and policies
🔹 Prevent horizontal privilege escalation
🔹 Design ownership-based access rules
🔹 Implement refresh tokens & secure sessions
🔹 Protect APIs from abuse using rate limiting
🔹 Add logging and auditing for security visibility
🔹 Think like a backend security engineer

🧱 How This Course Is Structured?

The course follows a professional security progression:

1️⃣ Open & vulnerable API
2️⃣ Authentication (JWT)
3️⃣ Authorization (roles)
4️⃣ Ownership rules (policies)
5️⃣ Session security (refresh tokens)
6️⃣ Abuse protection (rate limiting)
7️⃣ Visibility (logging & auditing)

Each layer builds on the previous one —

exactly how real systems evolve in production.

🧑‍💻 Who This Course Is For?

✅ Backend developers using ASP.NET Core
✅ Web & mobile developers consuming APIs
✅ Junior developers seeking real security skills
✅ Self-taught developers preparing for professional work

❌ Not for people looking for copy-paste snippets without understanding

⚠️ What This Course Is NOT?

❌ Not an ASP.NET Identity course
❌ Not OAuth / OpenID Connect
❌ Not theory-only
❌ Not framework magic

📌 This course focuses on core security concepts you can reuse everywhere.

🎓 Certification & Learning Outcomes

🏅 Professional Certificate of Completion

Upon successful completion of this course, the learner will earn a

Certificate in Secure RESTful API Engineering with ASP.NET Core, verifying the ability to:

🔹 Design and implement JWT-based authentication systems

🔹 Apply role-based, policy-based, and ownership-based authorization🔹 Prevent common API security vulnerabilities

🔹 Secure API sessions using refresh tokens

🔹 Protect APIs from abuse using rate limiting strategies

🔹 Implement logging and auditing for security visibility

🔹 Design API security before writing code, not after

🔐 This certification reflects security engineering competence, not just framework usage.

🎓 Final Outcome

After this course, you won’t just know how to secure an API.

You will be able to:

🔹 Design security intentionally
🔹 Explain your decisions confidently
🔹 Spot security flaws in other APIs
🔹 Build backend systems companies can trust

🔐 This is the difference between writing APIs and engineering secure systems.
