function Convert-RequirementValue { <# .SYNOPSIS Normalizes activation requirement values for consistent comparison. .DESCRIPTION Converts activation requirement strings to a standardized format by: - Handling null/empty/none values - Normalizing MFA references - Standardizing justification references - Sorting and deduplicating multiple requirements .PARAMETER Value The activation requirement value to normalize. .OUTPUTS String. The normalized requirement value. .EXAMPLE $normalized = Convert-RequirementValue -Value "MFA, justification" # Returns: "Justification,MFA" .EXAMPLE $normalized = Convert-RequirementValue -Value "none" # Returns: "" #> [CmdletBinding()] param([Parameter()][string]$Value) if (-not $Value) { return '' } $v = $Value.Trim() if ($v -eq '') { return '' } # Handle explicit "none" values if ($v -match '^(none|null|no(ne)?requirements?)$') { return '' } # Split on comma / semicolon and process each token $tokens = $v -split '[,;]+' | ForEach-Object { $_.Trim() } | Where-Object { $_ } $normalized = foreach ($token in $tokens) { switch -Regex ($token) { '^(mfa|multifactorauthentication)$' { 'MFA'; break } '^(justification)$' { 'Justification'; break } default { $token } } } # Sort and deduplicate, then join ($normalized | Sort-Object -Unique) -join ',' } |
