FAQ

To quote MDN:

Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement to distribution of malware.

To enable CSP, you need to configure your web server to return the Content-Security-Policy HTTP header.
