<h3>API Security is Not Optional</h3><p>APIs serve as the gateways to your server databases. If left unsecured, malicious actors can extract sensitive user records or execute destructive queries. Here is how modern software engineers secure their API endpoints.</p><h3>1. JSON Web Token (JWT) Authorization</h3><p>Never rely on cookie-based sessions for mobile or third-party client integrations. Use OAuth2 protocol or JSON Web Tokens (JWT) to validate request authorization. Ensure tokens are signed using secure hashing algorithms (like HS256 or RS256) and have strict expiration lifespans.</p><h3>2. Rate Limiting and Throttling</h3><p>Prevent brute-force attacks and Denial of Service (DoS) outages by restricting the number of API requests a user or IP address can make within a specified timeframe (e.g., maximum 100 requests per minute). Use Redis or API gateways to track call frequencies dynamically.</p><h3>3. Strict Input Validation & Prepared Statements</h3><p>Validate all incoming request bodies and query parameters on the server side. Never concatenate user input directly into SQL commands. Always use parameterized PDO prepared statements to block SQL injection attempts completely.</p>
