- Test Definition Placeholders
- Steps to function to account for new logic and create an updated test definition object when version 4.0.0 is selected.
- Test-AdministrativeAccountCompliance4 function for v4.0.0 rec# 1.1.1 test.
- Updated Get-CISMgOutput function to include the new test definition case for 1.1.1.
- Updated Get-CISMgOutput function to include the new test definition case for 1.1.1,1.1.4 and 2.1.7.
- New public function for generating version specific lists of recommendation numbers.
- Check in main public function to check for 4.0.0 rec numbers when 3.0.0 is selected as the M365 benchmark version.
- Rec numbers to include and exclude rec numbers for version 4.0.0 so the 'validate set' works correctly.
- Get-PhishPolicyCompliance and Get-ScopeOverlap private functions for 2.1.7 v4.
- Test-PhishPolicyCompliance4 function for 2.1.7 v4.
