Applications must be built to fail to a known safe state for defined types of failures.

Description
Failure in a known state can address safety or security in accordance with the mission/business needs of the organization. Failure in 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. Failure in a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized access to system resources. Applications or systems that fail suddenly and with no incorporated failure state planning may leave the hosting system available but with a reduced security protection capability. Preserving information system state information also facilitates system restart and return to the operational mode of the organization with less disruption of mission/business processes. An example is a firewall that blocks all traffic rather than allowing all traffic when a firewall component fails. This prevents an attacker from forcing a failure of the system in order to obtain access.
