CP-2 CONTINGENCY PLAN

Control: The organization:
a. Develops a contingency plan for the information system that:
- Identifies essential missions and business functions and associated contingency requirements;
- Provides recovery objectives, restoration priorities, and metrics;
- Addresses contingency roles, responsibilities, assigned individuals with contact information;
- Addresses maintaining essential missions and business functions despite an information system disruption, compromise, or failure;
- Addresses eventual, full information system restoration without deterioration of the security measures originally planned and implemented; and
- Is reviewed and approved by designated officials within the organization;


b. Distributes copies of the contingency plan to [Assignment: organization-defined list of 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 [Assignment: organization-defined frequency];
e. Revises 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; and
f. Communicates contingency plan changes to [Assignment: organization-defined list of key contingency personnel (identified by name and/or by role) and organizational elements].
Supplemental Guidance: Contingency planning for information systems is part of an overall organizational program for achieving continuity of operations for mission/business operations. Contingency planning addresses both information system restoration and implementation of alternative mission/business processes when systems are compromised. Information system recovery objectives are consistent with applicable laws, Executive Orders, directives, policies, standards, or regulations. In addition to information system availability, contingency plans also address other security-related events resulting in a reduction in mission/business effectiveness, such as malicious attacks compromising the confidentiality or integrity of the information system. Examples of actions to call out in contingency plans include, for example, graceful degradation, information system shutdown, fall back to a manual mode, alternate information flows, or operating in a mode that is reserved solely for when the system is under attack.
