<p>Security headers are HTTP response headers that web servers can send to enhance the security of web applications. These headers provide instructions to the web browser on how to handle certain aspects of the page and its interactions. By setting appropriate security headers, web developers can mitigate various types of attacks and vulnerabilities that can occur in web applications.</p> <p><strong>Here are some common security headers and their purposes:</strong></p> <ol> <li><strong>Content-Security-Policy (CSP)</strong>: This header defines which sources of content (scripts, styles, images, fonts, etc.) are allowed to be loaded and executed on a web page.
