A tabletop exercise is a simulation of a security incident or scenario that involves the participation of key stakeholders and decision-makers. It can be used to test and validate the effectiveness of the organization's plans, policies, and procedures, such as the risk management plan, incident response plan, and system security plan. A tabletop exercise can also help identify gaps or weaknesses in the plans and improve the communication and coordination among the participants. An internal management review, a control assessment, a peer review, or a scripting are other possible methods to evaluate and validate a new product's security capabilities, but they are not as comprehensive or interactive as a tabletop exercise.
