Details
The proper management of log records not only dictates proper archiving processes and procedures be established, it also requires allocating enough storage space to maintain the logs online for a defined period of time.
If adequate online log storage capacity is not maintained, intrusion monitoring, security investigations, and forensic analysis can be negatively affected.
It is important to keep a defined amount of logs online and readily available for investigative purposes. The logs may be stored on the application server until they can be archived to a log system or, in some instances, a Storage Area Networks (SAN). Regardless of the method used, log record storage capacity must be sufficient to store log data when the data cannot be offloaded to a log system or SAN.
