We recently underwent a security audit, in which it was determined that the naming convention of our servers posed a security threat. Our Proxy server is called Proxy, our File server is called ...._fileserver, etc. According to the audit this is a vulnerability. I am of the opinion, that once a hacker has penetrated your network, the server name is of minor importance, since he / she can determine what the server's purpose is by querying the services that are running on the particular server.
Does the name of the server really play such an important role in network security?
