It will pull the stig file using the provided parameters, merge in the data from the local settings file, and overwrite any settings that are provided in the exception list. .PARAMETER StigDataPath The root directoury to look for the DscStigXml files. This parameter us used to build the path to the translated DscStigXml file .PARAMETER OsVersion The version of the operating system STIG to lookup. This parameter us used to build the path to the translated DscStigXml file .PARAMETER StigVersion The version number to look up and return. This parameter us used to build the path to the translated DscStigXml file .PARAMETER StigException A hashtable os exceptions to overwrite STIG settings. .PARAMETER StigExceptionFile A XML file that contains a list of exceptions to overwrite the STIG settings. .EXAMPLE Get the 2.8 version of the Windows Server 2012 R2 STIG from the C:\Stigs directory. Get-StigData -OsVersion 2012R2 -StigVersion 2.8 -StigDataPath c:\Stigs .EXAMPLE Get the 2.8 version of the Windows Server 2012 R2 STIG from the C:\Stigs directory and overwrites the STIG setting for V-1079 with 0 before returnign the data.
