Data Synchronization must be disabled.

Description

Discussion Text

Disables data synchronization in Microsoft Edge. This policy also prevents the sync consent prompt from appearing. If this policy is not set or applied as recommended, users will be able to turn sync on or off. If this policy is applied as mandatory, users will not be able to turn on sync.

Checks

DISA STIG (Manual Reference)

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Disable synchronization of data using Microsoft sync services" must be set to "Enabled".

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

If the value for "SyncDisabled" is not set to "REG_DWORD = 1", this is a finding.
