Key Elements for a Business Case: Information Security Manager

B.

As an information security manager, the business case for a new security system is an essential tool for justifying investment in new security initiatives. This document should address the key aspects of the new system, including the benefits it will provide and the costs associated with its implementation.

Of the options given, the MOST important aspect that should be included in the business case is B. Risk reduction associated with the system.

Here's why:

A. Effectiveness of controls While the effectiveness of controls is important, it is not the most critical factor to include in a business case for a new security system. Controls can be effective in a variety of ways, and their effectiveness should be considered as part of the overall risk management strategy. However, the primary goal of implementing a new security system is to reduce the risks that the organization faces, rather than simply demonstrating that controls are effective.

C. Audit-logging capabilities Audit-logging capabilities are important for monitoring system activity and identifying potential security incidents. However, they are not the most critical factor to include in a business case for a new security system. Audit-logging capabilities are just one aspect of a broader security strategy, and their inclusion in a business case should be justified based on their contribution to overall risk reduction.

D. Benchmarking results Benchmarking results can provide useful information about how the new system compares to other solutions in the market. However, while benchmarking can be helpful in the decision-making process, it is not the most critical factor to include in a business case for a new security system. The primary focus should be on how the new system will reduce the risks that the organization faces, rather than on how it compares to other solutions in the market.

B. Risk reduction associated with the system The MOST important factor to include in a business case for a new security system is the risk reduction associated with the system. The business case should clearly articulate how the new system will reduce risks to the organization, and should provide evidence to support this claim. This could include data on the types of threats that the organization faces, the potential impact of these threats, and how the new system will mitigate these risks. By focusing on risk reduction, the business case can demonstrate the value that the new security system will provide to the organization and make a compelling case for investment.
