STIG ID: WN16-CC-000320  |  SRG: SRG-OS-000341-GPOS-00132 |  Severity: medium |  CCI: CCI-001849 |  Vulnerability Id: V-224939 | 

Vulnerability 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

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\System\

Value Name: MaxSize

Type: REG_DWORD
Value: 0x00008000 (32768) (or greater)

Fix

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.
