A proposal designed to gain buy-in from senior management for a new security project will be MOST effective if it includes:

Senior management's primary responsibility is to ensure the organization's profitability, strategic alignment, and shareholder value. Therefore, proposals for new projects, including security initiatives, are most effectively communicated in business and financial terms. A projected return on investment (ROI) directly translates the security project's value into a quantifiable financial metric that management can use to compare against other business investments. It frames the security expenditure not as a cost center, but as an investment that protects assets, avoids financial losses, and enables business objectives, making it the most persuasive element for gaining executive buy-in.

A. An analysis of the current threat landscape is important for context but fails to directly articulate the project's financial benefit or business value to the organization.

B. Historical data of reported incidents provides justification for action but is a reactive measure and does not quantify the future financial benefits of a proactive investment.

D. An industry benchmarking gap analysis shows how an organization compares to its peers but does not, in itself, provide a compelling financial reason to fund a specific project.

"Business Case Development." The manual states

"The business case is used to justify the resources and funding necessary to implement the strategy... It should include a cost-benefit analysis

which identifies the potential benefits of the program in business terms and the costs of the resources needed." ROI is a primary method for expressing a cost-benefit analysis.

438-457. This foundational academic paper argues that information security decisions should be treated as economic decisions. The authors state that the optimal amount to invest in information security is found by weighing the marginal costs against the marginal benefits

which is the core principle of an ROI calculation (p. 441). This economic framing is essential for communicating with senior management. (https://doi.org/10.1145/581271.581274)
