Title

The System event log size must be configured to 32768 KB or greater.

Control

If the system is configured to send audit records directly to an audit server, this is NA. This must be documented with the ISSO. 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\System\ Value Name: MaxSize Value Type: REG_DWORD Value: 0x00008000 (32768) (or greater)

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.

Fix

If the system is configured to send audit records directly to an audit server, this is NA. This must be documented with the ISSO. Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Event Log Service >> System >> "Specify the maximum log file size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "32768" or greater.
