IT risk scenarios are the descriptions or representations of the possible or hypothetical situations or events that may cause or result in an IT risk for the organization. IT risk scenarios usually consist of three elements: a threat or source of harm, a vulnerability or weakness, and an impact or consequence.
The best approach to use when creating a comprehensive set of IT risk scenarios is to map scenarios to a recognized risk management framework, which is an established or recognized model or standard that provides the principles, guidelines, and best practices for the organization’s IT risk management function. Mapping scenarios to a recognized risk management framework can help the organization to create a comprehensive set of IT risk scenarios by providing the following benefits:
It can ensure that the IT risk scenarios are relevant, appropriate, and proportional to the organization’s IT objectives and needs, and that they support the organization’s IT strategy and culture.
It can ensure that the IT risk scenarios are consistent and compatible with the organization’s IT governance, risk management, and control functions, and that they reflect the organization’s IT risk appetite and tolerance.
It can provide useful references and benchmarks for the identification, analysis, evaluation, and communication of the IT risk scenarios, and for the alignment and integration of the IT risk scenarios with the organization’s IT risk policies and standards.
The other options are not the best approaches to use when creating a comprehensive set of IT risk scenarios, because they do not provide the same level of detail and insight that mapping scenarios to a recognized risk management framework provides, and they may not be specific or applicable to the organization’s IT objectives and needs.
Deriving scenarios from IT risk policies and standards means creating or generating the IT risk scenarios based on the rules or guidelines that define and describe the organization’s IT risk management function, and that specify the expectations and requirements for the organization’s IT risk management function. Deriving scenarios from IT risk policies and standards can help the organization to create a consistent and compliant set of IT risk scenarios, but it is not the best approach, because it may not cover all the relevant or significant IT risks that may affect the organization, and it may not support the organization’s IT strategy and culture.
Gathering scenarios from senior management means collecting or obtaining the IT risk scenarios from the senior management or executives that oversee or direct the organization’s IT activities or functions. Gathering scenarios from senior management can help the organization to create a high-level and strategic set of IT risk scenarios, but it is not the best approach, because it may not reflect the operational or technical aspects of the IT risks, and it may not involve the input or feedback from the other stakeholders or parties that are involved or responsible for the IT activities or functions.
Benchmarking scenarios against industry peers means comparing and contrasting the IT risk scenarios with those of other organizations or industry standards, and identifying the strengths, weaknesses, opportunities, or threats that may affect the organization’s IT objectives oroperations. Benchmarking scenarios against industry peers can help the organization to create a competitive and innovative set of IT risk scenarios, but it is not the best approach, because it may not be relevant or appropriate for the organization’s IT objectives and needs, and it may not comply with the organization’s IT policies and standards.
