Setting aside capital to invest in Information Technology (IT) security is critical in the current digital age. In almost all large (or small) corporations, it is prudent to allocate a sufficient amount of resources to IT infrastructure. However, it is often difficult to determine at what level it is appropriate to invest in IT security in addition to the point at which the rate of return of this investment begins to diminish. This chapter examines methods to help determine the appropriate investment allocation to IT security in addition to how to apply these methods. It also looks at some of the assumptions and pitfalls of each.

Investing in information technology (IT) security is a critical decision in the digital age. And, in most organizations, it is wise to allocate a significant amount of resources to IT infrastructure. However, it is difficult to determine how much to invest in IT as well as quantifying the maximum threshold where the rate of return of this investment is diminishing. The main research question in this paper is: how much and what financial resources should be allocated to IT security? This paper analyzes different practices and techniques used to determine the calculation for investments in IT security and analyzes and recommend some suitable methods for deciding how much should be invested in IT security.

The case centers on Shilling & Smith's acquisition of Xteria Inc. and the resulting need to quickly scale the company's IT infrastructure to accommodate the acquisition. The case is based on a real leasing problem faced by a major retail firm in the Chicago area when it purchased a small credit card processing firm and scaled the operations to handle the retail firm's credit card transactions. The CIO of Shilling & Smith needs to determine which lease option is the best means of providing the technical infrastructure needed to support the firm after the acquisition of Xteria. Several issues will drive this decision, including the value and useful life of the equipment, as well as the strategic context of the firm. This case examines how to evaluate different lease options when acquiring data center information technology infrastructure. Specifically, the case addresses software vs. hardware leasing, different lease terms, and choosing between different lease structures depending on the strategy and needs of a company. This case enables students to understand the different types of technology leases and in which situations these leases would be employed.The Shilling & Smith case examines how to evaluate different lease options when acquiring data center information technology infrastructure. Specifically, students learn software vs. hardware leasing, different lease terms, and how to choose between different lease structures depending on the strategy and needs of the company. A secondary objective of the case is to teach students the important components and relative costs of information technology infrastructure.
