Once a STIG rule is identified as a windows feature rule, it is passed to the WindowsFeatureRuleConvert class for parsing and validation. #> class WindowsFeatureRuleConvert : WindowsFeatureRule { <# .SYNOPSIS Empty constructor for SplitFactory #> WindowsFeatureRuleConvert () { } <# .SYNOPSIS Converts a xccdf STIG rule element into a Windows Feature Rule .PARAMETER XccdfRule The STIG rule to convert #> WindowsFeatureRuleConvert ([xml.xmlelement] $XccdfRule) : base ($XccdfRule, $true) { $this.SetFeatureName() $this.SetFeatureInstallState() if ($this.conversionstatus -eq 'pass') { $this.SetDuplicateRule() } $this.SetDscResource() } #region Methods <# .SYNOPSIS Extracts the feature name from the check-content and sets the value .DESCRIPTION Gets the feature name from the xccdf content and sets the value.

[bool] HasMultipleRules () { return (Test-MultipleWindowsFeatureRule -FeatureName $this.Name) } <# .SYNOPSIS Splits a rule into multiple checks .DESCRIPTION Once a rule has been found to have multiple checks, the rule needs to be split. This method splits a windows feature into multiple rules. Each split rule id is appended with a dot and letter to keep reporting per the ID consistent. An example would be is V-1000 contained 2 checks, then SplitMultipleRules would return 2 objects with rule ids V-1000.a and V-1000.b .PARAMETER CheckContent The rule text from the check-content element in the xccdf #> [string[]] SplitMultipleRules () { return (Split-WindowsFeatureRule -FeatureName $this.Name) } hidden [void] SetDscResource () { # Assigns the appropriate Windows Feature DSC Resource if ($null -eq $this.DuplicateOf) { if ($global:stigTitle -match 'Windows 10') { $this.DscResource = 'WindowsOptionalFeature' } else { $this.DscResource = 'WindowsFeature' } } else { $this.DscResource = 'None' } } #endregion } |
