Title

The firewall must fail to a secure state upon the failure of the following: system initialization, shutdown, or system abort. (Cat II impact)

Discussion

Failure to a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized access to system resources. Network elements that fail suddenly and with no incorporated failure state planning may leave the hosting system available but with a reduced security protection capability. Preserving the information system state information also facilitates system restart and return to the operational mode of the organization with less disruption to mission-essential processes.

Check Content
