Title: Incident Response Testing

Practice:
Test the organizational incident response capability.

CMMC Clarification:
Testing an organization's incident response capability validates existing plans as well as highlight lapses or changes within the environment. The test should seek to address questions like what happens during an incident, who is responsible for incident management, what tasks are assigned within the IT organization, what support would be needed from legal, public affairs, or other business component, how are resources obtained if needed during the incident, and how is law enforcement involved. Any negative impacts to the normal day-to-day mission when responding to an incident should also be identified and documented.

Example
As CISO, you decide to conduct an incident response table top exercise. The exercise plans to simulate an attacker gaining access to the network through a compromised server. When scheduling the exercise you include relevant IT staff such as security, database, network, and system administrators. You also request a representative from legal, HR, and the communications department. As the exercise begins you provide a scenario to the team. You have key questions aligned with the response plans to guide the exercise. During the exercise you focus on how the team executes the organization's incident response plan. At the end of the test, you conduct a debrief with everyone that was involved to provide feedback and develop improvements to the incident response plan.
