The SBRU information system includes four subsystems: Resort relations, Student booking, Accounting and finance, and Social networking. The first three are purely Web applications, so access to those occurs through an Internet connection to a Web server at the SBRU home office. However, the Social networking subsystem has built-in chat capabilities. It relies on Internet access, as students compare notes before they book their travel reservations and as they chat while traveling. To function properly, the system obviously requires a wireless network at each resort. SBRU isn’t responsible for installing or maintaining the resort wireless network; they only plan to provide some design specifications and guidelines to each resort. The resort will be responsible for connecting to the Internet and for providing a secure wireless environment for the students. 1. For which subsystem(s) is (are) integrity and security controls most important? Why? 2. What data should be encrypted during transmission through resort wireless networks to SBRU systems? Does your answer change if students interact with SBRU systems using a cell phone (directly, or as a cellular modem)?
