| Associating event types with detected events in the logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured firewall. Without this capability, it would be difficult to establish, correlate, and investigate the events related to an outage or attack. Therefore, log records must be protected from unauthorized access, including from legitimate administrators who do not have a need for this type of access. Without this protection, a compromise or loss of log data needed for incident analysis or risk assessment could result.
Only individuals who have been designated by the Information Assurance Manager should be members of the group with access to the logs; this includes the System Administrators responsible for maintaining the network. The directory and file permissions of the logs must be set to only allow those authorized individuals or groups to view the records. |
