Establishing executive management support is the most important success factor when introducing risk management in an organization. This is because executive management support can help ensure that risk management is aligned with the organization's vision, mission, and strategy, as well as provide the necessary resources, authority, and accountability for risk management activities. Executive management support can also help foster a risk-aware culture, promote stakeholder engagement, and facilitate risk communication and reporting. According to the CRISC Review Manual 2022, one of the key elements of IT governance is to obtain executive management support and commitment for risk management1. According to the web search results, executive management support is a critical success factor for risk management in various contexts and industries234.

An IT risk threat analysis is best used to establish risk scenarios. A risk scenario is a description of a possible event or situation that may affect the achievement of the IT objectives. A risk scenario consists of three elements: a threat, a vulnerability, and an impact. A threat is a potential cause of an unwanted incident. A vulnerability is a weakness or flaw that can be exploited by a threat. An impact is the consequence or effect of the incident on the IT objectives. An IT risk threat analysis is a technique that identifies and evaluates the threats that may pose a risk to the IT assets and processes. An IT risk threat analysis can help to establish risk scenarios by providing the information and context for the threat element of the risk scenario. The other options are not as directly related to an IT risk threat analysis, as they are related to the outcomes, measures, or responsibilities of the IT risk management process, not the inputs or sources of the IT risk scenarios.

A threat and vulnerability assessment is a process that identifies and evaluates the potential sources and impacts of risk events on an organization's assets, processes, and objectives. It also estimates the probability of occurrence and the severity of consequences for each risk event. A threat and vulnerability assessment is the best way to quantify the likelihood of risk materialization, as it provides a numerical or qualitative measure of the risk exposure and the level of uncertainty associated with the risk scenarios.
