An organization's risk management team wants to develop IT risk scenarios to show the impact of collecting and storing credit card information. Which of the following is the MOST comprehensive…

Top-down analysis starts from a high-level risk and decomposes it, but it might not fully capture all the detailed sequences of events and intermediate control failures that an event tree does.

Event tree analysis is a bottom-up, inductive method that starts with an initiating event (e.g., a data breach or system compromise related to credit card information) and systematically maps out the subsequent sequence of events and their potential outcomes, considering the success or failure of various safety functions or controls. This approach comprehensively illustrates the cascading impacts and different possible scenarios stemming from an initial risk event.

Control gap analysis identifies missing or ineffective controls but does not inherently model the progression and impact of a risk scenario as comprehensively as an event tree.

Bottom-up analysis generally refers to identifying risks from granular components, but event tree analysis is a specific and highly effective method *within* a bottom-up approach for scenario modeling, focusing on event sequences and outcomes.
