9.3.5 (L1) Ensure 'Windows Firewall: Public: Settings: Apply local connection security rules' is set to 'No'

Information

This setting controls whether local administrators are allowed to create connection security rules that apply together with connection security rules configured by Group Policy.

The recommended state for this setting is: No

Users with administrative privileges might create firewall rules that expose the system to remote attack.

Solution

To establish the recommended configuration via GP, set the following UI path to No :

Computer Configuration\Policies\Windows Settings\Security Settings\Windows Defender Firewall with Advanced Security\Windows Defender Firewall with Advanced Security\Windows Firewall Properties\Public Profile\Settings Customize\Apply local connection security rules

Impact:

Administrators can still create local connection security rules, but the rules will not be applied.
