Section 1: Foundation of the Study

The majority of business information is stored electronically, creating the need for a system of securing this information. As the systems providing computer and internet security becomes more and more complex, security is increasingly compromised. Interlopers and hackers continue to create new and more creative means of gaining entry to information stored on networks, and users are facing an increased number of security attacks. Surprisingly, despite the variety and amount of security risks, security tools designed to counter these are slow to develop appear for business consumption (Garcia-Teodoro et al, 2009).

Abstract

Ever since deregulation in the airline industry, airlines have had the freedom, to select their choice of routes and have been given the freedom to determine fares. The paper gives a discussion of three basic route architecture networks that are in adoption, in the airline industry. These route networks include hub and spoke, point to point and multi-hub networks. Hub and spoke network is the most widely used route network architecture owing to its high cost and revenue advantages.

One way of preventing FMA attacks includes increasing the key length to 48 bits, which allows the IV to double up and combine with the secret key making the secret key more complicated (Singh, Singh, and Joseph, 2008). Incorporating a temporary key integrity protocol (TKIP) in a WEP helps to avoid weak keys and further obscures the secret key. This is possible since the TKIP changes the secret key with each packet (Beck, 2008). The decision to use layered defense mechanism to prevent WPA attacks is accurate. Using a layered network such as the authenticated network architecture (ANA) allows limited different ...

Company network architecture

Part I In designing a network, several factors are considered and are dictated by the use of the network. Looking at the case in hand, the network is supposed to address the five departments each separately, communication within the departments and within the local geographical locations (California and New Jersey) and intercity communication between the two business units. Looking at the five departments, each department should have its own network so as to operate effectively. This means that the department will have its own network architecture depending on the number of employees it has. The main objective of ...

Use of UTP and Optic cable in network design Looking at the various aspects of both the UTP and optic cable, optic cable has more advantages than the twisted pair cables. However, due to economic constraints and other aspects of the network being designed, the network designer and administrator may opt to use the UTP instead of the optic cable in some parts of the network architecture instead of a purely optic cable network. Looking into Gates network design and the basic requirements of the three units to use the network, one can use either of the two ...

Recommended Design

The recommended design is a client server network. The client server network involves the connection of at least two computers. The client computer, in this case, is the computer that requests an application. These may include the different workstations and laptops. The server is the computer that takes action on the requests made by clients. Implementation of the client-server network becomes efficient since, in case of business expansion, fewer disruptions will be experienced. The resources and data security will be handled through the server. This type of network design allows easier access to the server from various locations and platforms ...

The Top-Down Approach

Network Architecture and Design: The Top-Down Approach

Network architecture and design are many times two separate stages in a network implementation project. McCabe (2007) identifies network architecture as a higher level concept of a network. He says that it focuses on more general relationships between the major components of a network. For example, "addressing and routing, network management, performance, and security." (p. 211). The design stage of the project normally starts after the higher level architectural plan has been approved. This is where the real detailed work starts and the nuts and bolts start to come together. In designing your network, ...
