What is a Content Security Policy (CSP)?

A Content Security Policy (CSP) is a powerful security feature that helps prevent cross-site scripting (XSS), clickjacking, and other code injection attacks on websites. By specifying allowed content sources, a CSP restricts what resources (like JavaScript, CSS, images, fonts, etc.) can be loaded by the browser.
