HTTP security headers are response parameters from the server that instruct browsers on how to restrict page executions and resource requests. Properly configured headers prevent client-side vulnerabilities like XSS, clickjacking, MIME-sniffing, and protocol downgrades.
Strict-Transport-Security (HSTS) forces browsers to load your website exclusively over secure HTTPS connections, preventing man-in-the-middle decryption of traffic during initial plain-text HTTP redirects.
The X-Frame-Options header determines whether your page can be embedded inside frame tags on external websites. Configuring it to SAMEORIGIN prevents clickjacking attacks by blocking malicious frame overlays.
