REST API Security Essentials: Best Practices for Securing APIs 🔒

Securing REST APIs is critical to prevent unauthorized access, data breaches, and cyberattacks. Poorly secured APIs can expose sensitive data, leading to serious security risks.

This guide covers:
✔ Why REST API Security is Important
✔ Top REST API Security Threats
✔ Best Practices for Securing REST APIs
✔ Implementation Examples in Spring Boot

Let’s get started!

🔹 Why is REST API Security Important?

A secure API ensures:
✅ Confidentiality — Only authorized users can access data.
✅ Integrity — Data remains unmodified and secure.
✅ Availability — Protection against denial-of-service (DoS) attacks.

💡 Real-World API Security Incidents

• Facebook (2019): A misconfigured API leaked 419 million phone numbers.
• Twitter (2020): A vulnerability exposed phone numbers and emails.

🚨 A single security loophole can expose millions of users!
