How to Implement HTTP Security Headers (HSTS, CSP, X-Frame-Options)
HTTP security headers instruct modern web browsers how to restrict dangerous behaviors, preventing clickjacking, protocol downgrades, and data leakage.
1. Strict-Transport-Security (HSTS)
Enforces that browsers must communicate exclusively over HTTPS, eliminating man-in-the-middle SSL stripping attacks.
2. X-Frame-Options: DENY
Prevents your website from being embedded inside invisible <iframe> tags on third-party domains, completely blocking clickjacking exploits.
