Information

The recommended state for this setting is: 16,384 KB or greater

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 16,384 KB or greater :

Computer Configuration\Policies\Windows Settings\Security Settings\Windows Firewall with Advanced Security\Windows Firewall with Advanced Security\Windows Firewall Properties\Domain Profile\Logging Customize\Size limit (KB)

Impact:

The log file size will be limited to the specified size, old events will be overwritten by newer ones when the limit is reached.
