Verify the following registry configuration:

Using the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown

Value Name: bProtectedMode
Type: REG_DWORD
Value: 1

If the value for bProtectedMode is not set to "1" and Type is not configured to REG_DWORD or does not exist, this is a finding.

Admin Template path: Computer Configuration > Administrative Templates > Adobe Acrobat Pro DC Classic > Preferences > 'Protected Mode' must be set to 'Enabled'.

This policy setting requires the installation of the AcrobatProDCClassic custom templates included with the STIG package. "AcrobatProDCClassic.admx" and "AcrobatProDCClassic.adml" must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.
