Question

A university Chief Information Security Officer is analyzing various solutions for a new project involving the upgrade of the network infrastructure within the campus. The campus has several dorms (two-four person rooms) and administrative buildings. The network is currently setup to provide only two network ports in each dorm room and ten network ports per classroom. Only administrative buildings provide 2.4 GHz wireless coverage. The following three goals must be met after the new implementation: 1. Provide all users (including students in their dorms) connections to the Internet. 2. Provide IT department with the ability to make changes to the network environment to improve performance. 3. Provide high speed connections wherever possible all throughout campus including sporting event areas. Which of the following risk responses would MOST likely be used to reduce the risk of network outages and financial expenditures while still meeting each of the goals stated above?

Options

  • AAvoid any risk of network outages by providing additional wired connections to each user
  • BTransfer the risk of network outages by hiring a third party to survey, implement and manage
  • CAccept the risk of possible network outages and implement a WLAN solution to provide
  • DMitigate the risk of network outages by implementing SOHO WiFi coverage throughout the

Explanation

C (Accept the risk and implement a WLAN solution) is the only option that realistically satisfies all three goals. Goal 3 - high-speed coverage in sporting event areas - cannot be achieved with wired infrastructure alone, and extending wired ports to athletic fields is impractical. Wireless (WLAN) is the only technology that can blanket the entire campus including outdoor areas. The risk accepted is that wireless networks are inherently less reliable than wired, but this is a calculated, acknowledged trade-off. Option A (more wired ports) cannot cover outdoor sporting areas. Option B (third-party management) transfers some risk but does not define the technology solution. Option D (SOHO WiFi) uses consumer-grade equipment not designed for high-density campus deployments, which would not reliably meet the high-speed goal.
