Technical Paper: Risk Assessment 2

Global Finance Inc. uses a backbone network as a basis for its network connection. A backbone can tie several local area networks together to provide for the passage of data between the individual networks and from the networks to the internet or other external network resources. The main reason for using a backbone network is to improve overall performance of a larger network by creating separate LAN’s for groups of users who communicate primarily with each other. The backbone network also makes it possible to extend the overall range of the combined networks beyond that of a single LAN. (Englander, 200, page 407)

One important use for backbone networks, which can be seen in the diagram, is the ability for the network to extend the wireless access beyond the limited range of an individual access point. Multiple access points are distributed over a large area to provide a wider range of coverage. This method also improves the speed and computer performance for individual users. (Englander, 200, page 407)

Because of the hierarchical concept of the network diagram, this backbone network layout can be called a 3-tiered network. A 3-tier application is an application program that is organized into three major parts, each of which is distributed to a different place or places in a network. The first tier is the application user's workstation that contains the programming that provides the graphical user interface, also called a GUI, and application-specific entry forms or interactive windows. The second tier is the business logic that acts as the server for client requests from workstations which then determines what data is needed (and where it is located) and acts as a client in relation to a third tier of programming that might be located on a mainframe computer. The final tier...
