9.3.8 Ensure 'Windows Firewall: Public: Logging: Log dropped packets' is set to 'Yes'

Information

Use this option to log when Windows Firewall with Advanced Security discards an inbound packet for any reason. The log records why and when the packet was dropped. Look for entries with the word DROP in the action column of the log.

The recommended state for this setting is: Yes.

If events are not recorded it may be difficult or impossible to determine the root cause of system problems or the unauthorized activities of threat actors.

Solution

To establish the recommended configuration via GP, set the following UI path to Yes :

Computer Configuration\Policies\Windows Settings\Security Settings\Windows Defender Firewall with Advanced Security\Windows Defender Firewall with Advanced Security\Windows Defender Firewall Properties\Public Profile\Logging Customize\Log dropped packets

Impact:

Information about dropped packets will be recorded in the firewall log file.
