Inspector to query for default ftp site

Any way to query FTP default site for these policy settings using BigFix?

Here is powershell method

Get-ItemProperty -Path ‘IIS:\Sites\Default FTP Site’ -Name ftpServer.security.ssl.dataChannelPolicy
Get-ItemProperty -Path ‘IIS:\Sites\Default FTP Site’ -Name ftpServer.security.ssl.controlChannelPolicy

Not natively that I know of, but I have some analyses that work by querying the web.config and parsing the XML. Have you investigated that route?
