Related Controls

The controls below (if any) were marked by NIST as being related to PE-11.

Control	Description
AT-3	The organization provides role-based security training to personnel with assigned security roles and responsibilities: a: Before authorizing access to the information system or performing assigned duties; b: When required by information system changes; and c: [organization-defined frequency] thereafter.
CP-2	The organization: a: Develops a contingency plan for the information system that: 1: Identifies essential missions and business functions and associated contingency requirements; 2: Provides recovery objectives, restoration priorities, and metrics; 3: Addresses contingency roles, responsibilities, assigned individuals with contact information; 4: Addresses maintaining essential missions and business functions despite an information system disruption, compromise, or failure; 5: Addresses eventual, full information system restoration without deterioration of the security safeguards originally planned and implemented; and 6: Is reviewed and approved by [organization-defined personnel or roles]; b: Distributes copies of the contingency plan to [organization-defined key contingency personnel (identified by name and/or by role) and organizational elements]; c: Coordinates contingency planning activities with incident handling activities; d: Reviews the contingency plan for the information system [organization-defined frequency]; e: Updates the contingency plan to address changes to the organization, information system, or environment of operation and problems encountered during contingency plan implementation, execution, or testing; f: Communicates contingency plan changes to [organization-defined key contingency personnel (identified by name and/or by role) and organizational elements]; and g: Protects the contingency plan from unauthorized disclosure and modification.
CP-7	The organization: a: Establishes an alternate processing site including necessary agreements to permit the transfer and resumption of [organization-defined information system operations] for essential missions/business functions within [organization-defined time period consistent with recovery time and recovery point objectives] when the primary processing capabilities are unavailable; b: Ensures that equipment and supplies required to transfer and resume operations are available at the alternate processing site or contracts are in place to support delivery to the site within the organization-defined time period for transfer/resumption; and c: Ensures that the alternate processing site provides information security safeguards equivalent to those of the primary site.

Enhancements

The controls below (if any) add on to the requirements of PE-11.

Control	Description
PE-11(1)	The organization provides a long-term alternate power supply for the information system that is capable of maintaining minimally required operational capability in the event of an extended loss of the primary power source.
PE-11(2)	The organization provides a long-term alternate power supply for the information system that is: (a): Self-contained; (b): Not reliant on external power generation; and (c): Capable of maintaining [] in the event of an extended loss of the primary power source.
