An accountant at a small business is trying to understand the value of a server to determine if the business can afford to buy another server for DR.

The latest independent research shows that cyber attacks involving SCADA systems grew an average of 15% per year in each of the last four years, but that this year's growth has slowed to around 7%. Over the same time period, the number of attacks against applications has decreased or stayed flat each year. At the start of the measure period, the incidence of PC boot loader or BIOS based attacks was negligible. Starting two years ago, the growth in the number of PC boot loader attacks has grown exponentially. Analysis of these trends would seem to suggest which of the following strategies should be employed?
A. Spending on SCADA protections should stay steady; application control spending should increase substantially and spending on PC boot loader controls should increase substantially.
B. Spending on SCADA security controls should stay steady; application control spending should decrease slightly and spending on PC boot loader protections should increase substantially.
C. Spending all controls should increase by 15% to start; spending on application controls should be suspended, and PC boot loader protection research should increase by 100%.
D. Spending on SCADA security controls should increase by 15%; application control spending should increase slightly, and spending on PC boot loader protections should remain steady.

A web developer is responsible for a simple web application that books holiday accommodations. The front-facing web server offers an HTML form, which asks for a user's age. This input gets placed into a signed integer variable and is then checked to ensure that the user is in the adult age range.
Users have reported that the website is not functioning correctly. The web developer has inspected log files and sees that a very large number (in the billions) was submitted just before the issue started occurring. Which of the following is the MOST likely situation that has occurred?
A. The age variable stored the large number and filled up disk space which stopped the application from continuing to function. Improper error handling prevented the application from recovering.
B. The age variable has had an integer overflow and was assigned a very small negative number which led to unpredictable application behavior. Improper error handling prevented the application from recovering.
C. Computers are able to store numbers well above "billions" in size. Therefore, the website issues are not related to the large number being input.
D. The application has crashed because a very large integer has lead to a "divide by zero". Improper error handling prevented the application from recovering.
