I wonder if non-edible nuts were considered. For instance: wing(nut), lug(nut), and cage(nut).

Also, after "left" and "right" were used, you could always use "deez". :)

This has been a fantastic thread, thanks for all the input and creative
naming scheme ideas.

With new servers hosted by University IT here, the Windows Systems group
has settled on the ‘its-service-p##’ type style, where ‘p’ stands for
production, ‘t’ would be test, etc. It seems some other institutions do
similar and even add more information such as location, and you brought
up a good point about a nmap scan can easily enumerate the services on a
box, so I feel more comfortable with that now. And segmenting DNS into
different zones is a great idea too.

Thanks,

 What kinds of naming conventions do everyone follow when building new

 Currently, our Windows hosts are named following the pattern‘its-w2ks#’

 or similar, where the # is the next in the sequence, and the names are

 published in DNS. What are the potential drawbacks or using a scheme

 like this? Do you think it is any better or worse from a security

 perspective than using something like‘its-oracle-1’  which has the

 service right in the name? We’re concerned about disclosing the purpose

 of the machine via its name, and are trying to get an idea of what other

 schools do for their machines. Thanks in advance.



For some servers, which are for internal ITS use only, there is really

no naming convention in place. Mythological figures and horrible puns

tend to be the norm.



For user-facing servers, the DNS name generally reflects the purpose or

service of the server. For example, our domain controllers are named

"ad-canisius"  and"ad-canisius2", our Exchange mail stores are"store01"

and"store02", etc. There's probably a slight risk of revealing

information by putting a service right in the name, but frankly, it's no

more information than a simple nmap fingerprinting scan would be likely

to provide.
