Description
Logging the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or to simply identify an improperly configured system. Audit and event log data must be protected from unauthorized access, including from legitimate administrators who do not have a need for this type of access. Unauthorized deletion of logs or events may obfuscate evidence of an attack. Event log entries must not be deleted.
