CP — CONTINGENCY PLANNING
CP-4: CONTINGENCY PLAN TESTING
NIST 800-53R4 Membership CP-4:
- a. Tests the contingency plan for the information system [Assignment: organization-defined frequency] using [Assignment: organization-defined tests] to determine the effectiveness of the plan and the organizational readiness to execute the plan;
- b. Reviews the contingency plan test results; and
- c. Initiates corrective actions, if needed.
Methods for testing contingency plans to determine the effectiveness of the plans and to identify potential weaknesses in the plans include, for example, walk-through and tabletop exercises, checklists, simulations (parallel, full interrupt), and comprehensive exercises. Organizations conduct testing based on the continuity requirements in contingency plans and include a determination of the effects on organizational operations, assets, and individuals arising due to contingency operations. Organizations have flexibility and discretion in the breadth, depth, and timelines of corrective actions.

CP-4 (1) CONTINGENCY PLAN TESTING | COORDINATE WITH RELATED PLANS
NIST 800-53R4 Membership CP-4 (1):
The organization coordinates contingency plan testing with organizational elements responsible for related plans.
Plans related to contingency plans for organizational information systems include, for example, Business Continuity Plans, Disaster Recovery Plans, Continuity of Operations Plans, Crisis Communications Plans, Critical Infrastructure Plans, Cyber Incident Response Plans, and Occupant Emergency Plans. This control enhancement does not require organizations to create organizational elements to handle related plans or to align such elements with specific plans. It does require, however, that if such organizational elements are responsible for related plans, organizations should coordinate with those elements.
RELATED CONTROLS: CP-4 (1)
CP-4 (2) CONTINGENCY PLAN TESTING | ALTERNATE PROCESSING SITE
The organization tests the contingency plan at the alternate processing site:
- (a) To familiarize contingency personnel with the facility and available resources; and
- (b) To evaluate the capabilities of the alternate processing site to support contingency operations.
Supplemental Guidance: NONE
RELATED CONTROLS: CP-4 (2)
CP-4 (3) CONTINGENCY PLAN TESTING | AUTOMATED TESTING
The organization employs automated mechanisms to more thoroughly and effectively test the contingency plan.
Automated mechanisms provide more thorough and effective testing of contingency plans, for example: (i) by providing more complete coverage of contingency issues; (ii) by selecting more realistic test scenarios and environments; and (iii) by effectively stressing the information system and supported missions.
CP-4 (4) CONTINGENCY PLAN TESTING | FULL RECOVERY / RECONSTITUTION
NIST 800-53R4 Membership CP-4 (2):
The organization includes a full recovery and reconstitution of the information system to a known state as part of contingency plan testing.
Supplemental Guidance: NONE
