Definition

The set of practices protecting API endpoints from unauthorized access, abuse, and data exposure — covering authentication, authorization, rate limiting, and monitoring.

مجموعة الممارسات التي تحمي نقاط نهاية API من الوصول غير المُصرَّح به والإساءة وكشف البيانات.

Why It Matters

APIs are the primary attack surface of modern apps. Unlike web pages, APIs are machine-readable and trivially automated — one BOLA vulnerability can expose every user's data.

APIs هي سطح الهجوم الأساسي للتطبيقات الحديثة. يمكن أتمتتها بسهولة — يمكن لثغرة BOLA واحدة كشف بيانات كل مستخدم.

Full Definition

API security covers the OWASP API Security Top 10: Broken Object Level Authorization (BOLA/IDOR), Broken Authentication, Unrestricted Resource Consumption (no rate limiting), Broken Function Level Authorization, Server-Side Request Forgery, Security Misconfiguration, Lack of Protection from Automated Threats. Key practices: authenticate every request (JWT, API keys), authorize at the resource level (not just the endpoint), validate all inputs, rate limit all endpoints, return minimum necessary data, log all requests for anomaly detection, and never expose internal IDs directly.

يشمل أمان API ضوابط تحمي من OWASP API Security Top 10. الممارسات الرئيسية: مصادقة كل طلب والتفويض على مستوى المورد والتحقق من صحة جميع المدخلات وتحديد معدل جميع نقاط النهاية وإعادة الحد الأدنى من البيانات.

AI Builder Tips

Avoid these mistakes when using API Security:

Authorizing at the endpoint level but not the object level → Checking if the user is logged in is not enough. Check if they OWN that specific resource: `order.userId === req.user.id`.

Returning full database objects → Always project only the fields the client needs. Avoid returning sensitive fields like password hashes or internal IDs.

Exposing API keys in client-side code or URL query parameters → They appear in browser history and referrer headers. Keep API keys server-side and pass them from environment variables.
