How do I secure my website against XSS injection

Hi Experts,
I have an ASP.Net website.  I want to secure against XSS injection and other threats.  How do I accomplish this?  Do I have to do something with the ValidateRequest attribute?

Thanks in advance,

In reality there are 2 ways to protect against XSS.

Option 1) have the code validated for security best practices. depending on the size of the codebase, this can be a very expensive option. As new vulnerabilities are released, you will have to check the code for the new troublesome code.

Option 2) put in a web application firewall. This is the option I went with. This is even a compensating control for having code verified in the process of becoming PCI compliant. There are a number of WAF appliances out there. I have tried a few, but i chose to use a FortiWeb as I was familiar with the FortiNet architecture at the time. This option is usually cheaper than having code security-validated, and will be much cheaper than having your code security-validated after your next major revision.

Your best bet is contact a security consulting firm and see what they recommend for your particular setup.
