$FileSecurity.GetAccessRules($IncludeExplicitRules,$IncludeInheritedRules,$AccountType) | Resolve-Ace This uses .Net Core as the source of the access list It uses the GetAccessRules method on the [System.Security.AccessControl.FileSecurity] class The targetType parameter of the method is used to specify that the accounts in the ACL are returned as NT account names (DOMAIN\User) .EXAMPLE [String]$FolderPath = 'C:\Test' [System.IO.DirectoryInfo]$DirectoryInfo = Get-Item -LiteralPath $FolderPath [System.Security.AccessControl.DirectorySecurity]$DirectorySecurity = $DirectoryInfo.GetAccessControl('Access') [System.Security.AccessControl.AuthorizationRuleCollection]$AuthRules = $DirectorySecurity.Access $AuthRules | Resolve-Ace Use the .Net Framework (or legacy .Net Core up to 2.2) as the source of the access list Only works in Windows PowerShell Those versions of .Net had a GetAccessControl method on the [System.IO.DirectoryInfo] class This method is

Example: 1st ticket - Grant access to folder1 and all of its contents 2nd ticket - Unable to access folder1\subfolder1 (oops, nobody knew subfolder1 had inheritance disabled) Recommended: Enable inheritance. To achieve the desired behavior, consider these alternatives in order of preference: 1. Modify ACE inheritance and propagation flags (instead of ACL inheritance). 2. Move folders up higher in the folder structure if they require access not achievable with inheritance and propagation flags. Example: Ticket - Grant access to folder1 but none of its subfolders Not Recommended - Disabling inheritance of all ACEs on all subfolders of folder1 Recommended - The ACE on folder1 which grants access should have the flags set to TODO VERIFY CORRECT CONFIG, BELOW ALL SETTINGS ARE LISTED INSTEAD: Propagation flags: 0 (None) No inheritance flags are set. 1 (NoPropagateInherit) ACE is not propagated to child objects. 2 (InheritOnly) ACE is propagated only to child objects. This includes both container and leaf child objects. Inheritance flags: 0 (None) ACE is inherited by child container objects. 1 (ContainerInherit) ACE is inherited by child container objects. 2 (ObjectInherit) ACE is inherited by child leaf objects. This ensures the new access will not propagate to any subfolders of folder 1, without disrupting ACL inheritance. #> $ItemsWithBrokenInheritance = $AclByPath.Keys | Where-Object -FilterScript { $AclByPath[$_].AreAccessRulesProtected #-and -not $AllowDisabledInheritance[$_] } # Groups that were used in ACEs but do not match the specified naming convention # Invert the naming convention scriptblock (because we actually want to identify groups that do NOT follow the convention) $ViolatesAccountConvention = [scriptblock]::Create("!($AccountConvention)") $NonCompliantAccounts = $PrincipalByID.Values | Where-Object -FilterScript { $_.SchemaClassName -eq 'Group' } | Where-Object -FilterScript $ViolatesAccountConvention if ($NonCompliantAccounts) { $AceGUIDsWithNonCompliantAccounts = $AceGuidByID[$NonCompliantAccounts] } if ($AceGUIDsWithNonCompliantAccounts) { $ACEsWithNonCompliantAccounts = $AceByGUID[$AceGUIDsWithNonCompliantAccounts] } $ACEsWithUsers = [System.Collections.Generic.List[PSCustomObject]]::new() $ACEsWithUnresolvedSIDs = [System.Collections.Generic.List[PSCustomObject]]::new() $ACEsWithCreatorOwner = [System.Collections.Generic.List[PSCustomObject]]::new() ForEach ($ACE in $AceByGUID.Values) { # ACEs for users (recommend replacing with group-based access on any folder that is not a home folder) if ( $PrincipalByID[$ACE.IdentityReferenceResolved].SchemaClassName -eq 'User' -and $_.IdentityReferenceSID -ne 'S-1-5-18' -and # The 'NT AUTHORITY\SYSTEM' account is part of default Windows file permissions and is out of scope $_.SourceOfAccess -ne 'Ownership' # Currently Ownership is out of scope.
