Control Selection Approaches

C.

The best approach for selecting controls to minimize information security risks is through risk assessment. Risk assessment is a systematic and structured process of identifying, analyzing, evaluating, and prioritizing risks associated with an organization's information assets. This process enables organizations to understand their security posture and helps them identify the most significant risks to their information assets.

The risk assessment process involves identifying the assets that need protection, identifying the threats and vulnerabilities that can exploit those assets, analyzing the likelihood and impact of those threats and vulnerabilities, and then selecting and implementing appropriate controls to mitigate the identified risks. This approach ensures that controls are tailored to the specific risks faced by the organization, which makes them more effective in minimizing those risks.

Cost-benefit analysis is another approach that can be used to select controls. However, it is not the best approach because it focuses more on the cost of implementing controls rather than the effectiveness of the controls in mitigating the identified risks. This approach may lead organizations to select controls that are cheaper but less effective in minimizing risks.

Control-effectiveness is another approach that can be used to select controls. This approach involves selecting controls based on their effectiveness in mitigating specific risks. While this approach is useful, it can be challenging to assess the effectiveness of controls in isolation from other factors.

Industry best practices are also a valuable source of guidance for selecting controls. However, they should not be the only consideration. Industry best practices should be used in conjunction with risk assessment to ensure that controls are appropriate for the organization's specific risks and requirements.

In summary, the best approach for selecting controls to minimize information security risks is through risk assessment. This approach ensures that controls are tailored to the specific risks faced by the organization, which makes them more effective in minimizing those risks. Cost-benefit analysis, control-effectiveness, and industry best practices can also be used, but they should be used in conjunction with risk assessment.
