Answer

To prevent cross-site scripting (XSS) attacks, you should implement a combination of input validation, output encoding, and security headers.

Example Concept: Cross-site scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. To mitigate XSS, use input validation to ensure only expected data is processed, output encoding to safely render user input, and security headers like Content-Security-Policy to restrict the execution of scripts.

Additional Comment:

Always validate and sanitize user inputs on both client and server sides.
Use libraries or frameworks that automatically handle output encoding for you.
Implement a strict Content-Security-Policy to control which scripts can be executed.
