@august_hudson Something like this:

In web development, preventing XSS attacks is a critical concern. Some of the ways I handle XSS attacks include input validation and sanitizing user inputs such as removing special characters. Encoding untrusted data such as HTML, JavaScript, and CSS before it is sent to the user's browser is another approach to prevent XSS attacks. Also, keeping updated with the latest security best practices and staying vigilant for any potential vulnerabilities is crucial to prevent cross-site scripting attacks. Lastly, implementing security protocols such as Content Security Policy (CSP) which restricts where user-input data can be loaded provide an effective defense against the XSS threats.

As a web developer, my approach to handling cross-site scripting attacks begins with ensuring that all user input is validated on both the client and server side. I implement safeguards such as encoding user input on output to prevent any harmful code from being executed. Additionally, I make use of HTTP-only cookies to prevent attackers from stealing session data and limit the use of inline scripts and styles. It is also crucial to stay up to date with the latest security vulnerabilities and regularly scan our codebase for any potential flaws. Finally, I work closely with our security team to develop a comprehensive plan of action in case of any attack and ensure that we have appropriate backups and disaster recovery plans in place.
