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

Asked on Oct 13, 2025

Answer

To prevent cross-site scripting (XSS) attacks, you should implement a combination of input validation, output encoding, and security headers. These measures help ensure that malicious scripts cannot be executed in the context of your website.

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 restrict input to expected formats, output encoding to safely render user data, and security headers like Content-Security-Policy to control resources the browser is allowed to load.

Additional Comment:

Use libraries or frameworks that automatically handle output encoding, such as React or Angular.
Implement a strong Content-Security-Policy to limit the sources of executable scripts.
Regularly update and patch your web applications to protect against known vulnerabilities.
