HTTP security headers are directives passed from the web server to the client browser. They instruct the browser on how to behave when handling the site's content, significantly reducing the risk of common vulnerabilities like Cross-Site Scripting (XSS), clickjacking, and code injection.
Modern web applications rely on headers like Content-Security-Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to harden their defense. Missing or misconfigured headers leave your application exposed to client-side attacks. Auditing these headers ensures compliance with security best practices.
