X-Frame Options
An HTTP response header that prevents clickjacking by controlling if a site can be displayed within an iframe on another external domain.
X-Frame-Options is a security header that your web server sends to browsers, controlling whether your website can be embedded within frames or iframes on other domains. This protection prevents clickjacking attacks, where malicious sites overlay invisible frames containing your website over their own content, tricking users into clicking buttons or entering information they didn't intend to interact with. You can configure X-Frame-Options to completely deny framing (DENY), allow framing only from your own domain (SAMEORIGIN), or permit specific trusted domains (ALLOW-FROM). Most modern hosting platforms and content management systems make it easy to enable this header through configuration files or security plugins. Implementing X-Frame-Options is a simple but effective security measure that protects your users from sophisticated attacks while having no impact on normal website functionality. It's considered a best practice for web security and is often included in security audits and compliance requirements.
