Description
Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know when events occurred (date and time). Associating event types with detected events in the operating system audit logs provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured operating system. SMF data collection is the basic unit of tracking of all system functions and actions. Included in this tracking data are the audit records from each of the ACPs and system. If the required SMF data record types are not being collected, then accountability cannot be monitored, and its use in the execution of a contingency plan could be compromised.
