HTTP security headers are directives sent from a web server to a user’s browser to enhance the security of web applications, including those dealing with cryptocurrency transactions. They help protect users from various attacks like clickjacking, cross-site scripting (XSS), and content type sniffing.Common security headers include:1. **Content-Security-Policy (CSP)**: This header helps prevent XSS attacks by specifying which sources of content are trusted. It restricts where scripts, styles, and other resources can be loaded from.2. **Strict-Transport-Security (HSTS)**: This forces browsers to only interact with the server over a secure HTTPS connection, preventing downgrade attacks.3. **X-Content-Type-Options**: This header prevents browsers from interpreting files as a different MIME type than what is specified, mitigating content type sniffing risks.4. **X-Frame-Options**: This restricts how a site can be embedded in frames, reducing the risk of clickjacking.Implementing these headers helps secure platforms that handle cryptocurrency, ensuring safer transactions and protecting user data.
