WSUS Firewall rules do not use names nor groupnames

Question

Hi everyone,
Today I've been playing around with PowerShell Workflows and the firewall cmdlets on my test environment. (Great stuff, Thanks
Scripting Guys)
After working out a little workflow I noticed that the firewall rules that were made by the WSUS feature installation had no Name nor DisplayGroup, only the DisplayName.
My test environment is made up from tree Server 2012 R2 servers with a domain.
The script I made :
workflow Get-AllFirewalls
Parallel{
InlineScript{
Get-NetFirewallRule -Enabled True -Action Allow |?{
$_.Profile -match "Any|Domain"
} | select Name,DisplayName,direction,DisplayGroup,
@{n='Port';e={($_|Get-NetFirewallPortFilter).LocalPort}},
@{n='Protocol';e={($_|Get-NetFirewallPortFilter).Protocol}},
@{n='Program';e={($_|Get-NetFirewallApplicationFilter).Program}}
$output = Get-AllFirewalls -PSComputerName (Get-ADComputer -Filter 'OperatingSystem -like "Windows Server*"').name
$output |Sort-Object DisplayGroup |Format-Table PSComputerName,Name,DisplayName,Direction,Port,Protocol,Program -GroupBy DisplayGroup -AutoSize
Now this is just for testing and I could get around the fact there are no proper names but I think it's sloppy not to fill the naming attributes.
Am I the only one with these results or is it just WSUS?

Answer 1

There are only two rules created, one for HTTP on port 8530 one for HTTPS on port 8531, and the latter isn't even used in most WSUS installations.
There is no Group Name, because this is not a GROUP of rules, it is two individual rules. One is always enabled; the second is optionally enabled WHEN the WSUS Server is configured to use SSL, and it's enabled by an administrative script provided in the
WSUS toolset.
Ergo, a server administrator never has to mess with these two rules at all, so, no, I think it's insignificant that these rules may be missing a couple of generally irrelevant attributes.
