Exam CISA topic 1 question 840 discussion

A: Periodic tabletop exercises involving key stakeholders. Tabletop exercises are simulations of cybersecurity incidents that involve key stakeholders from various departments and roles within an organization. These exercises help test and validate the effectiveness of the incident response process in a controlled and collaborative environment. They allow participants to practice their roles, identify weaknesses or gaps in the process, and improve coordination among different teams. Furthermore, tabletop exercises provide an opportunity to refine and update the incident response plan based on the lessons learned during the simulation. While options B, C, and D are important aspects of maintaining an effective incident response process, tabletop exercises go beyond documentation updates, training, or reporting incidents. They provide a real-world simulation that can help identify and address issues that may not become apparent through other means. Therefore, option A is the most comprehensive and proactive approach to ensuring the effectiveness of the cybersecurity incident response process.
