How can I protect my website from cross-site scripting attacks?
Asked on Oct 21, 2025
Answer
To protect your website from cross-site scripting (XSS) attacks, you should implement a combination of input validation, output encoding, and use of security headers. These measures help prevent malicious scripts from being executed in your users' browsers.
<!-- BEGIN COPY / PASTE -->
Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; object-src 'none';
<!-- END COPY / PASTE -->Additional Comment:
- Always validate and sanitize user inputs to prevent harmful data from being processed.
- Use output encoding to ensure data is safely rendered in the browser.
- Implement the
Content-Security-Policyheader to restrict sources of executable scripts. - Avoid using
'unsafe-inline'in CSP unless absolutely necessary, as it can weaken the policy.
