9.2.7 (L1) Ensure 'Windows Firewall: Private: Logging: Log dropped packets' is set to 'Yes'

Information

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 malicious users.

Solution

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

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

Impact:

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