I've been doing a security audit and found out you can easily identify host roles and running services just by their computer name (using nslookup).

I would like to report this so that they use less obvious computer names and it becomes harder for an attacker to identify machine roles on the network. I would like to give some weight to this proposal by linking to some security naming convention from a trusted organisation. After some search, I've been unable to find some. Is there any existing ?
