Powershell has a TrustedHost section that is configured like this:
winrm s winrm/config/client '@{TrustedHosts="CorpServer56"}'
What security is implied for CorpServer56? Is it just an ASCII name match on the host that is "trusted"?
I'm concerned about someone guessing a trusted host, and faking that name in order to gain access to a computer.
