WN11-AU-000505 - The security event log size must be configured to a value that holds at least one week's worth of audit records.

Information

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. System Administrators (SAs) must monitor the volume of security event audit records and increase the registry value for the log size as needed.

Solution

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 a value that will contain one week of audit records or greater.

If the system is configured to send audit records directly to an audit server, this must be documented with the ISSO.
