Most Useful Report for Senior Management

A.

When preparing a report for senior management, it is important to include information that is useful for evaluating changes in the organization's information security risk position. Of the options provided, the most useful in this regard is trend analysis.

Trend analysis involves examining historical data to identify patterns and trends over time. This can be useful for identifying changes in the organization's risk position, as well as identifying potential areas of concern. For example, if there has been a recent increase in security incidents or breaches, trend analysis may help identify the underlying causes and suggest appropriate remedial action.

Risk registers are also important for evaluating the organization's risk position, but they are typically more focused on identifying and assessing specific risks rather than tracking changes over time. A risk register may be useful for identifying areas of concern that need to be addressed, but trend analysis is better suited to identifying changes in risk levels over time.

Industry benchmarks can be useful for evaluating the organization's risk position relative to others in the same industry or sector, but they may not provide a complete picture of the organization's specific risk position or the effectiveness of its security controls.

Management action plans are important for identifying and tracking specific actions that are being taken to address identified risks or vulnerabilities. However, they may not provide a comprehensive view of the organization's overall risk position or how it is changing over time.

In summary, while all of these options can be useful for evaluating an organization's risk position, trend analysis is the most useful in a report to senior management for evaluating changes in the organization's information security risk position.
