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 content

If the system is configured to send audit records directly to an audit server, this is NA. If the following registry values do not exist or are not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\EventLog\Application\ Value Name: MaxSize Type: REG_DWORD Value: 0x00008000 (32768) (or greater) Registry Path: \SOFTWARE \Policies\Microsoft\Windows\EventLog\Security\ Value Name: MaxSize Type: REG_DWORD Value: 0x00030000 (196608) (or greater) Registry Path: \SOFTWARE \Policies\Microsoft\Windows\EventLog\Setup\ Value Name: MaxSize Type: REG_DWORD Value: 0x00008000 (32768) (or greater) Registry Path: \SOFTWARE \Policies\Microsoft\Windows\EventLog\System\ Value Name: MaxSize Type: REG_DWORD Value: 0x00008000 (32768) (or greater)

Fix text

Configure the following policy values as listed below: Computer Configuration >> Administrative Templates >> Windows Components >> Event Log Service >> Application >> "Maximum Log Size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "32768" or greater. Security >> "Maximum Log Size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "196608" or greater. Setup >> "Maximum Log Size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "32768" or greater. System >> "Maximum Log Size (KB)" to "Enabled" with a "Maximum Log Size (KB)" of "32768" or greater.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
