API Security:Why it matters

In this post, we’ll break down API security in a simple way, talk about why it’s important, and look at some real-world attacks. We’ll also introduce the OWASP API Security Top 10, a list of the most common API vulnerabilities. Let’s dive in!

Introduction

APIs (Application Programming Interfaces) are everywhere. They connect apps, power online services, and make our digital lives easier. But here’s the catch — if they’re not secured properly, they can be an open door for hackers.

Why Should You Care About API Security?

APIs handle sensitive data, from personal details to payment information. If an API isn’t secure, attackers can:

• Steal data — User info, payment details, and private messages can be exposed.
• Take over accounts — Weak authentication can let hackers log in as someone else.
• Crash services — A badly protected API can be taken down by too many requests (DoS attacks).
• Manipulate transactions — If security checks aren’t strict, attackers can change API requests to their advantage.
