Why HTTP Security Headers Matter
HTTP response headers can significantly improve your site's security posture by instructing browsers on how to behave when loading your content. Missing or misconfigured security headers leave your users exposed to attacks like clickjacking, XSS, and MIME-type sniffing.
Headers like Strict-Transport-Security (HSTS) force HTTPS connections. Content-Security-Policy (CSP) prevents script injection. X-Frame-Options prevents your page from being embedded in malicious iframes.
FAQ
How do I add security headers to my site?
For Apache, add them in your .htaccess file or httpd.conf. For Nginx, add them in your server block. For PHP, use header() calls. Most hosting control panels (cPanel, Plesk) also have a header management section.
