Description: Security headers are HTTP response headers that provide security information to the browser. Their main goal is to protect users and their data by establishing security policies that the browser must follow when interacting with a website’s content. These headers allow web developers to control critical aspects such as script execution, resource loading, and communication between different origins. By implementing security headers, common attacks like Cross-Site Scripting (XSS), Clickjacking, and Cross-Site Request Forgery (CSRF) can be mitigated. Some of the most commonly used headers include Content Security Policy (CSP), X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security. Each of these headers has a specific purpose and contributes to creating a safer environment for users. Properly configuring these headers not only enhances security but can also influence website performance, as a well-protected site can be more trustworthy and thus attract more traffic. In a world where cyber threats are becoming increasingly sophisticated, implementing security headers has become essential for any web developer looking to protect their site and its users.
