The most helpful input to develop risk scenarios associated with hosting an organization’s key IT applications in a cloud environment is conducting a risk workshop with key stakeholders. A risk workshop is a facilitated session that involves brainstorming, discussing, and analyzing the potential risks and opportunities related to a specific topic or project. A risk workshop helps to identify and prioritize the most relevant and significant risk scenarios, as well as to explore the possible causes, impacts, and responses. A risk workshop also helps to engage and align the key stakeholders, such as the business owners, IT managers, cloud providers, and risk experts, and to leverage their knowledge, experience, and perspectives. The other options are not as helpful as conducting a risk workshop, although they may provide some inputor information for the risk scenario development. Reviewing the results of independent audits, performing a site visit to the cloud provider’s data center, and performing a due diligence review are all activities that can help to assess the current state and performance of the cloud environment, but they do not necessarily generate or evaluate the risk scenarios. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.2.1, page 4-13.
