A security manager created new documentation to use in response to various types of security incidents. Which of the following is the next step the manager should take?

After creating new incident response documentation, the most critical next step is to conduct a tabletop exercise with the team. This allows the team to practice using the new procedures in a simulated, low-stress environment, identifying any ambiguities, gaps, or inefficiencies before a real incident occurs. This practical application helps validate the documentation's effectiveness and ensures the team understands their roles and responsibilities. Setting a data retention policy is important but is a separate policy decision, not directly related to validating new incident response procedures. Securely storing documents is a good practice but doesn't test the procedures themselves. Reviewing data classification policy is also important for incident response but doesn't provide the practical validation that a tabletop exercise offers.
