Discussion

Logs are essential to monitor the health of the system, investigate changes that occurred to the system, or investigate a security incident. When log processing fails, the events during the failure can be lost. To minimize the timeframe of the log failure, an alert needs to be sent to the SA and ISSO at a minimum. Log processing failures include, but are not limited to, failures in the application server log capturing mechanisms or log storage capacity being reached or exceeded. In some instances, it is preferred to send alarms to individuals rather than to an entire group. Application servers must be able to trigger an alarm and send an alert to, at a minimum, the SA and ISSO in the event there is an application server log processing failure.
