18.8.33.6.2 Ensure 'Allow network connectivity during connected-standby (plugged in)' is set to Disabled'

Info

This policy setting allows you to control the network connectivity state in standby on modern standby-capable systems.
The recommended state for this setting is: 'Disabled'.
Rationale:
Disabling this setting ensures that the computer will not be accessible to attackers over a WLAN network while left unattended, plugged in and in a sleep state.

Solution

To establish the recommended configuration via GP, set the following UI path to 'Disabled':
Computer Configuration\Policies\Administrative Templates\System\Power Management\Sleep Settings\Allow network connectivity during connected-standby (plugged in)
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template 'Power.admx/adml' that is included with the Microsoft Windows 10 Release 1607 & Server 2016 Administrative Templates (or newer).
Impact:
Network connectivity in standby (while plugged in) is not guaranteed. This connectivity restriction currently only applies to WLAN networks only, but is subject to change (according to Microsoft).
