Documented procedures are the best way to enable effective IT control implementation. Documented procedures are the specific actions or steps that are performed to achieve the IT control objectives and mitigate the IT risks. Documented procedures provide clear guidance, consistency, and accountability for the IT control activities. Documented procedures also help to monitor and evaluate the effectiveness and efficiency of the IT controls, and to identify and address any gaps or weaknesses. The other options are not as effective as documented procedures, although they may support or complement the IT control implementation. Key risk indicators (KRIs) are metrics that measure the likelihood and impact of IT risks, but they do not specify how to implement the IT controls. Information security policies and standards are high-level statements that define the IT security goals and requirements, but they do not detail how to implement the IT controls. References = Risk and Information Systems Control Study Manual, Chapter 1, Section 1.3.2, page 1-15.

IT risk scenarios are hypothetical situations that describe how IT-related risks can affect the organization’s objectives, operations, or assets1. IT risk scenarios help to make IT risk more concrete and tangible, and to enable proper risk analysis and assessment2. IT risk scenarios are developed after IT risks are identified, and are used as inputs for risk analysis, where the frequency and impact of the scenarios are estimated3.

The most important factor to the successful development of IT risk scenarios is threat and vulnerability analysis. Threat and vulnerability analysis is the process of identifying and evaluating the potential sources and causes of IT risks, such as malicious actors, natural disasters, human errors, or technical failures4. Threat and vulnerability analysis can help to:

Define the scope and boundaries of the IT risk scenarios, and ensure that they are relevant and realistic

Identify the critical assets, processes, or functions that are exposed or affected by the IT risks, and assess their value and importance to the organization

Determine the likelihood and methods of the threat events, and the existing or potential weaknesses or gaps in the IT control environment

Estimate the potential consequences and impacts of the IT risks, such as financial losses, operational disruptions, reputational damages, or compliance violations5

A KRI is a measure used by an organization to measure the health of a particular risk. In this case, the risk practitioner is developing a metric to measure the risk associated with security threats that were not identified by antivirus software12.

The most important factor to the effectiveness of key performance indicators (KPIs) is relevance. KPIs are metrics that measure the achievement of the objectives or the performance of the processes. Relevance means that the KPIs are aligned with and support the strategic goals and priorities of the organization, and that they reflect the current and desired state of the outcomes or outputs. Relevance also means that the KPIs are meaningful and useful for the decision makers and stakeholders, and that they provide clear and actionable information for improvement or optimization. The other options are not as important as relevance, as they arerelated to the approval, review, or automation of the KPIs, not the quality or value of the KPIs. References = Risk and Information Systems Control Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.2: Key Performance Indicators, page 183.
