I am trying to block Windows 7 clients from accessing the internet. I have followed the steps here: https://live.paloaltonetworks.com/t5/Configuration-Articles/Custom-vulnerability-signature-for-ident...
but I am unclear on what to set for the Pattern. Any suggestions/help to accomplish that goal will be appreciated.
User-Agent strings can be set separately and aren't absolute indications that the machine is running Windows 7. Running things in compatibility mode for instance can change the User-Agent string automatically. It's likely that this is a "false positive" in the sense that the machine isn't running Windows 7, but it was sending the User-Agent string associated with Windows 7.
