Failure in a known state can address safety or security in accordance with the mission needs of the organization. Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving network element state information helps to facilitate network element restart and return to the operational mode of the organization with less disruption to mission-essential processes.
