How can I prevent cross-site scripting attacks on my website?

Answer

To prevent cross-site scripting (XSS) attacks, you should sanitize user inputs, use Content Security Policy (CSP), and implement secure headers. These measures help ensure that malicious scripts cannot be executed in your users' browsers.

Example Concept: Cross-site scripting (XSS) is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. To mitigate XSS, use input validation and output encoding, and implement security headers like "Content-Security-Policy" to control which scripts can be executed on your site.

Additional Comment:

Always validate and sanitize user inputs on both client and server sides.
Set the "Content-Security-Policy" header to restrict resources the browser is allowed to load for your site.
Use libraries and frameworks that automatically escape HTML, such as React or Angular, to prevent XSS.
