Assessment Title

Rule Text

Importing of extensions must be disabled.

Description

Discussion Text

Allows users to import extensions from another browser into Microsoft Edge. If this policy is enabled, the Extensions check box is automatically selected in the Import browser data dialog box. If this policy is disabled, extensions are not imported at first run, and users cannot import them manually.

Checks

DISA STIG (Manual Reference)

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Allow importing of extensions" must be set to "disabled".

Use the Windows Registry Editor to navigate to the following key:
HKLM\SOFTWARE\Policies\Microsoft\Edge

If the value for "ImportExtensions" is not set to "REG_DWORD = 0", this is a finding.
