If the referenced application is not installed on the system, this is NA. This is applicable to unclassified systems, for other systems this is NA. Run "Windows PowerShell" with elevated privileges (run as administrator). Enter "Get-ProcessMitigation -Name wordpad.exe". (Get-ProcessMitigation can be run without the -Name parameter to get a list of all application mitigations configured.) If the following mitigations do not have a status of "ON", this is a finding: DEP: Enable: ON Payload: EnableExportAddressFilter: ON EnableExportAddressFilterPlus: ON EnableImportAddressFilter: ON EnableRopStackPivot: ON EnableRopCallerCheck: ON EnableRopSimExec: ON The PowerShell command produces a list of mitigations; only those with a required status of "ON" are listed here.
