.SYNOPSIS
Converts path that contains AppLocker specific variables into to normal paths.
Author: @oddvarmoe
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
Takes path as input and normalizes it by changing AppLocker specific parameters into paths.
If variable that is sent into the function resolves to two paths (ex: System32/SysWOW64) the function will return both.
It also resolves paths containing ADS rules such as "%windir%\folder:*".
.EXAMPLE
PS C:\> Expand-PALPath -Path "%windir%\temp"
C:\Windows\temp
.EXAMPLE
PS C:\> Expand-PALPath -Path "%programfiles%"
C:\Program Files
C:\Program Files (x86)

.SYNOPSIS
Lists paths that are missing on the filesystem that is allowed for execution.

Required Dependencies: Get-PALWriteablePaths, Get-PALRules
Optional Dependencies: None
.DESCRIPTION
Retrieves the path from all the allowed AppLocker path rules and checks if the path is missing or not.
It will list out the paths it cannot find and these paths can likely be exploited if the user can create the folders.
Currently it does not resolve * in paths so it may contain false positives.
Outputs: Name,Path
.PARAMETER RuleSection
What sort of section you want the rules for. Default is "All
Can be "All","Dll","Exe","Script","Appx","Msi". This Parameter is passed to the Get-PALRules.

<#
.SYNOPSIS
Checks given path/file if it is allowed or denied by the AppLocker rules.
When a folder path is checked it will return allow if the folder path is allowed in either EXE,DLL,MSI,SCRIPT,APPX.
When a file path is checked it will only check the correct section. EX: file.exe is only checked against EXE path rules and will only return deny or allow.
The function does not handle exceptions yet.

.DESCRIPTION
Gets all the AppLocker path rules and enumerates if the supplied path or file is allowed or denied.
Returns Allow or Deny.
.PARAMETER Path
The Path you want to verify. Can either be a path to a folder or file.
Parameter is mandatory.
.PARAMETER SID
The SID you want to get the rules for.
Default is S-1-1-0. (Admin rules will not show up default as a consequence of that.)

.PARAMETER OfflineXML
Path to OfflineXML that you have exported.
This makes the function parse that file instead of the current AppLocker policy on the machine this script is running on.
.EXAMPLE
Tests status of cmd.exe. This is allowed in this example.
PS C:\> Get-PALPathStatus -Path "C:\windows\system32\cmd.exe"
