A benchmark analysis is a process of comparing the organization’s performance, practices, and processes with those of other organizations in the same industry or sector. A benchmark analysis can provide the most useful information when determining the frequency of risk assessments, because it can help the organization to identify the best practices, standards, and expectations for security risk management in its industry. A benchmark analysis can also help the organization to assess its current level of maturity, capability, and compliance in relation to security risk management, and to determine the gaps and areas for improvement. By conducting a benchmark analysis, the organization can establish a realistic and appropriate frequency of risk assessments that aligns with its industry norms and its own risk profile. The other options are not as useful as a benchmark analysis, because they do not provide a comprehensive and relevant view of the security risk management landscape, but rather focus on specific or partial aspects of the organization’s situation. References = Risk and Information Systems Control Study Manual, Chapter 1, Section 1.3.2, page 18.
