Fix Recommendation

Ensure the following mitigations are configured as shown for WINWORD.EXE:

DEP:
Override DEP: False

ASLR:
ForceRelocateImages: ON

Payload:
OverrideExportAddressFilter: False
OverrideExportAddressFilterPlus: False
OverrideImportAddressFilter: False
OverrideEnableRopStackPivot: False
OverrideEnableRopCallerCheck: False
OverrideEnableRopSimExec: False

Application mitigations defined in the STIG are configured by a DoD EP XML file included with the Windows 10 STIG package in the "Supporting Files" folder.

The XML file is applied with the group policy setting Computer Configuration >> Administrative Settings >> Windows Components >> Windows Defender Exploit Guard >> Exploit Protection >> "Use a common set of exploit protection settings" configured to "Enabled" with file name and location defined under "Options:". It is recommended the file be in a read-only network location.
