Title

Windows Server 2019 Security event log size must be configured to 196608 KB or greater. (Cat II impact)

Discussion

Inadequate log size will cause the log to fill up quickly. This may prevent audit events from being recorded properly and require frequent attention by administrative personnel.

Check Content

If the system is configured to write events directly to an audit server, this is NA. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\EventLog\Security\ Value Name: MaxSize Type: REG_DWORD Value: 0x00030000 (196608) (or greater)

Fix Text

Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Event Log Service >> Security >> "Specify the maximum log file size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "196608" or greater.
