The firewall implementation must fail to an organizationally defined known state for organizationally defined types of failures.

Description
Failure to a known state can address safety or security in accordance with the mission needs of the organization. Failure to a state that is known to be secure helps prevent the loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. An example of this would be an organizational policy that firewalls be configured to "fail closed", so if a firewall failure occurs, all data transit through the firewall must stop and no new sessions can pass through the firewall.

Check Text ( C-45558r1_chk )
Examine the configuration settings for hardware and/or application failover of the firewall. Verify the firewall is configured to fail to an organizationally defined secure state. Verify this secure state prevents or limits unauthorized, unaudited access. If the system failover or hardware/software failure settings are not configured to fail to an organizationally defined known state for organizationally defined types of failures, this is a finding.
