I have a web site that does E-commerce. We've been dinged about our security not being PCI DSS compliant because our AWS based servers are returning an HTTP response with:
Server: CloudFront
as a parameter. I can see how advertising your server type as being a clue for hackers, but I've been unable to find any references as to how to shut this off in CloudFront or WAF (I do see references to shutting it off in Apache HTTP). Our actual server is a Linux system, and CloudFront is obfuscating this information by rewriting the header, but how can I remove it? Or is simply rewriting it as CloudFront adequate?
