IR-3: INCIDENT RESPONSE TESTING
TAILORED FOR INDUSTRIAL CONTROL SYSTEMS
ICS Control Baselines:
- Moderate
- High
The organization tests the incident response capability for the information system [Assignment: organization-defined frequency] using [Assignment: organization-defined tests] to determine the incident response effectiveness and documents the results.
SUPPLEMENTAL GUIDANCE
Organizations test incident response capabilities to determine the overall effectiveness of the capabilities and to identify potential weaknesses or deficiencies. Incident response testing includes, for example, the use of checklists, walk-through or tabletop exercises, simulations (parallel/full interrupt), and comprehensive exercises. Incident response testing can also include a determination of the effects on organizational operations (e.g., reduction in mission capabilities), organizational assets, and individuals due to incident response.
ICS SUPPLEMENTAL GUIDANCE
No ICS Supplemental Guidance.
RELATED CONTROLS: IR-3
RELATED CONTROLS: IR-3 (1)
CONTROL ENHANCEMENTS
IR-3 (1) INCIDENT RESPONSE TESTING | AUTOMATED TESTING
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization employs automated mechanisms to more thoroughly and effectively test the incident response capability.
Supplemental Guidance:
Organizations use automated mechanisms to more thoroughly and effectively test incident response capabilities, for example: (i) by providing more complete coverage of incident response issues; (ii) by selecting more realistic test scenarios and test environments; and (iii) by stressing the response capability.
RELATED CONTROLS: IR-3 (1)
IR-3 (2) INCIDENT RESPONSE TESTING | COORDINATION WITH RELATED PLANS
ICS Control Baselines:
- Moderate
- High
The organization coordinates incident response testing with organizational elements responsible for related plans.
Supplemental Guidance:
Organizational plans related to incident response testing include, for example, Business Continuity Plans, Contingency Plans, Disaster Recovery Plans, Continuity of Operations Plans, Crisis Communications Plans, Critical Infrastructure Plans, and Occupant Emergency Plans.
No ICS Supplemental Guidance.
