Description
Acrobat provides the ability for the user to store a list of websites with an associated behavior of allow, ask, or block. Websites that are not in this list are unknown. PDF files can contain URLs that will initiate connections to unknown websites in order to share or get information. That access must be restricted.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Verify the following registry configuration: Utilizing the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\cDefaultLaunchURLPerms\ Value Name: iUnknownURLPerms Type: REG_DWORD Value: 3 If the value for iUnknownURLPerms is not set to “3” and Type is not configured to REG_DWORD or does not exist, this is a finding. GUI path: Edit > Preferences > Trust Manager > In the 'Internet Access from PDF Files outside the web browser' section > Select 'Change Settings' option > In the 'PDF Files may connect to web sites to share or get information' section, if 'Block PDF files access to all web sites' is selected and greyed out (locked), then this is not a finding. If 'Custom setting' is checked, then in the 'Default behavior for web sites that are not in the above list' section, verify the radio button 'Block access' is checked and greyed out (locked) . If the box is not checked nor greyed out, this is a finding. Admin Template path: Computer Configuration > Administrative Templates > Adobe Acrobat Pro DC Continuous > Preferences > Trust Manager > 'Access to unknown websites' must be set to 'Enabled' and 'Block access' selected in the drop down box.
