Enhanced Security (ES) is a sandbox capability that restricts access to system resources. ES can be configured in two modes: Standalone mode is when Acrobat opens the desktop PDF client. ES Browser mode is when a PDF is opened via the browser plugin. When Enhanced Security is enabled and a PDF file tries to complete a restricted action from an untrusted location, a security warning must appear.Enhanced Security “hardens” the application against risky actions. It prevents cross domain access, prohibits script and data injection, blocks stream access to XObjects, silent printing, and execution of high privilege JavaScript.
Verify the following registry configuration: Utilizing the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown Value Name: bEnhancedSecurityStandalone Type: REG_DWORD Value: 1 If the value for bEnhancedSecurityStandalone is not set to “1” and Type is not configured to REG_DWORD or does not exist, this is a finding. GUI path: Edit > Preferences > Security (Enhanced) > In the 'Enhanced Security' section> Verify 'Enable Enhanced Security' checkbox is checked and greyed out (locked). If the box is not checked nor greyed out (locked), this is a finding. Admin Template path: Computer Configuration > Administrative Templates > Adobe Acrobat Pro DC Continuous > Preferences > Security (Enhanced) > 'Enable Enhanced Security Standalone' must be set to 'Enabled'. This policy setting requires the installation of the AcrobatProDCContinuous custom templates included with the STIG package.

Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
