sc-24

fail in known state

assessment objective:

Determine if:

sc-24[1]

the organization defines a known-state to which the information system is to fail in the event of a system failure;

sc-24[2]

the organization defines types of failures for which the information system is to fail to an organization-defined known-state;

sc-24[3]

the organization defines system state information to be preserved in the event of a system failure;

sc-24[4]

the information system fails to the organization-defined known-state for organization-defined types of failures; and

sc-24[5]

the information system preserves the organization-defined system state information in the event of a system failure.

potential assessment methods and objects:

Examine: [select from: System and communications protection policy; procedures addressing information system failure to known state; information system design documentation; information system configuration settings and associated documentation; list of failures requiring information system to fail in a known state; state information to be preserved in system failure; information system audit records; other relevant documents or records].

Interview: [select from: System/network administrators; organizational personnel with information security responsibilities; system developer].

Test: [select from: Automated mechanisms supporting and/or implementing fail-in-known state capability; automated mechanisms preserving system state information in the event of a system failure].
