Interval International is an online travel service that books to resorts for Timeshare Owners. Owners have booked trips for decades, but changes in technology have transformed the travel business in recent years. Timeshares companies have moved away from having owners contacting individual resorts with seasonal availability and migrated to a web application where owners can share their destination availability. The goal is to get a timeshare owner to be able to reserve a resort outside of their parent timeshare and travel to a different destination using the days and season that would be originally allotted to them. Interval International contracts with resorts all around the globe, especially in tropical destinations. The website shows information on each resort and includes prices, available rooms, and special features. Owners can research and book a room, enter their unique timeshare id to pull their basic rental information, and reserve based on the type of timeshare purchase. Interval International displays an entire summary of information for the user when they log into the site. Owners can either use their timeshare for an even exchange or book a weekend getaway that doesn't cost them the time from their parent resort.

Since owner timeshares can be different based on their purchased, the resorts also need access to the type of purchase from Interval International. They need to know about their bookings for the year, the room types that are booked, and so forth. Depending on it being an even exchange or weekend getaway, resorts might need to be paid by Interval International for the reservation. Resorts might also need to collect incidentals

PART 1

The Interval International information system includes four subsystems: Resort Relations, Owner 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 Interval International home office. However, the Social Networking subsystem has built in chat capabilities. It relies on Internet access, as Timeshare owners compare experiences before they book their travel reservations, and as they chat while travelling. To function properly, the system obviously requires a wireless network at each resort. Interval International 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 owners.

1. For which subsystem(s) is (are) integrity and security controls most important and why?
2. What data should be encrypted during transmission through resort wireless networks to Interval International systems? Does your answer change if owners' interface with Interval International thru a mobile app.

PART 2

Considering what you know so far about Interval International, complete the following tasks:

1. Develop a simple network diagram that includes all four Interval International subsystems (resort relations, Owner reservation, accounting/finance, and social networking) assuming that all server side hardware and software resides at the Interval International home office.
2. List the advantages and disadvantages of hosting all server-side hardware and software at the Interval International home office compared to using a large cloud service provider such as Amazon, or Microsoft.
3. Answer the following questions from the perspective of Interval International:
   1. Assuming that external hosting costs are roughly the equivalent to the cost of operating, staffing, and, maintaining a server room at the home office, do the benefits of external hosting outweigh the costs?
   2. Does your answer to the previous question change if external costs are 50% greater than operating, staffing, and, maintaining a server room at the home office?

PART 3

Interval International social networking subsystem requires an intuitive and engaging user-interface design for mobile-services. But the social networking subsystem can also play an important part in resort security. For example, each resort could use traveler location, interests, activities, and "likes" - all of which are available through the application - to monitor the well-being of travelers staying at the resort. Timeshare owners are older with family and are concerned about their safety - particularly at isolated resorts in foreign countries. Interval International and the participating resorts could keep track of where travelers are and who they are near, monitor messages about activities and parties, and anticipate crowded conditions or vulnerable travelers wandering off-site. For example, if a pool is overcrowded, some action can be taken. If messages refer to places off-site that are known to be dangerous, security can make an extra patrol. Although many people find this use of private information objectionable, others - particularly parents - find it essential.

Imagine resort security with a large, wide screen monitor tracking traveler activity. Design a main screen that includes multiple locations, paths and roads, traveler location, and status, messages traveling from traveler to traveler, and other features that security should monitor. Create a storyboard that shows an example of a pop-up alert and a menu of options that security might select after an alert. Should you also show security the staff members' location and status? How about clicking security staff members to send them a message? How about clicking a location to turn up the lights or to close a security ate? Be creative as you think through the design of possibilities. You should include four or five screen layouts for the storyboard
