This can help prevent many types of cross-site scripting attacks. Another way to protect your website from XSS attack is by implementing the following conditions:
1) Minimize data reuse within a page
2) Use proper input validation
3) Implement site-wide protections
How to Protect your Site from XSS Attacks?
In order to protect your website from XSS attacks there are certain steps that must be taken. First step is to make sure that all the scripts used in your site are properly encoded. Developers should encode all the scripts and HTML of their websites with content-encoding: gzip, deflate, or br, which makes it harder for hackers to inject malicious code into their site. Additionally, you should always use a unique URL when displaying any form on your website. This helps avoid CSRF attacks since a hacker cannot steal the cookie information without knowing the URL of the form.
