...Unit 5 Lab1 New Building – Wired and Wireless The advancements in technology have made it necessary to rely on a combination of solutions to keep the cost so there is not any sacrificing security. For the most part, the basis of the network will be a wired solution. A wired solution will keep the security high, so a hacker would have to be physically attached to the network to gain full access. Running a wired network is more cost effective because wireless technology is still new enough so the cost is higher. By running new wired networks, longevity can be built into it by planning ahead. Racks, patch cabling, and wired routers are less difficult to troubleshoot. A wireless solution is can be very attractive due to the fact that there are relatively few cables, but they are more susceptible to security issues and cost is higher than wired networks. This network is less of a physical set up and more of a logical network, due in part to assigning and managing all of the IP addresses. Wireless routers, wireless access points, and Wi-Fi network cards have their limitations, however they can be utilized in areas (such as an internet café) where security is not as important. The tools for both types of installs are mostly the same, with a few differences depending upon the cable types being used; the testing tools change a bit when going after the range of the wireless network. There are many apps for your smartphone that allow you to measure the strength of a wireless signal. You...

...White Paper Wireless LAN Security 802.11b and Corporate Networks 6303 Barfield Road · Atlanta, GA 30328 Tel: 404.236.2600 · Fax: 404.236.2626 WWireWireless Lan Security 802.11b Wireless LAN Security Introduction Although a variety of wireless network technologies have or will soon reach the general business market, wireless LANs based on the 802.11 standard are the most likely candidate to become widely prevalent in corporate environments. Current 802.11b products operate at 2.4GHz, and deliver up to 11Mbps of bandwidth – comparable to a standard Ethernet wired LAN in performance. An upcoming version called 802.11a moves to a higher frequency range, and promises significantly faster speeds. It is expected to have security concerns similar to 802.11b. This low cost, combined with strong performance and ease of deployment, mean that many departments and individuals already use 802.11b, at home or at work – even if IT staff and security management administrators do not yet recognize wireless LANs as an approved technology. This paper addresses the security concerns raised by both current and upcoming 802.11 network technologies. Wireless LAN Business Drivers Without doubt, wireless LANs have a high gee-whiz factor. They provide always-on network connectivity, but don’t require a network cable. Office workers can roam from meeting to meeting throughout a building, constantly connected to the same network resources enjoyed by wired, desk-bound coworkers...

Protecting Wireless LANs…………………………………………...13 V. Wireless LAN Security Summary……………………………………18 I. Introduction a. The 802.11 Wireless LAN Standard In 1997, the IEEE ratified the 802.11 Wireless LAN standards, establishing a global standard for implementing and deploying Wireless LANS. The throughput for 802.11 is 2Mbps, which was well below the IEEE 802.3 Ethernet counterpart. Late in 1999, the IEEE ratified the 802.11b standard extension, which raised the throughput to 11 Mbps, making this extension more comparable to the wired equivalent. The 802.11b also supports the 2 Mbps data rate and operates on the 2.4GHz band in radio frequency for high-speed data communications As with any of the other 802 networking standards (Ethernet, Token Ring, etc.), the 802.11 specification affects the lower layers of the OSI reference model, the Physical and Data Link layers. The Physical Layer defines how data is transmitted over the physical medium. The IEEE assigned 802.11 two transmission methods for radio frequency (RF) and one for Infrared. The two RF methods are frequency hopping spread-spectrum (FHSS) and direct sequence spread-spectrum (DSSS). These transmission methods operate within the ISM (Industrial, Scientific, and Medical) 2.4 GHz band for unlicensed use...

...of LTE from Verizon Wireless will empower the organization to be portable and maintain a fast, reliable, and secure connection among its mobile healthcare professionals. This will save money and allow for greater productivity. Business Problem with Benefits The Business problem that Tim and management have presented is that their business, a healthcare system, has doctors (both clinical and research) spread across western North Carolina and they sometimes do not have adequate infrastructure to transmit their research and clinical data (including data entry applications, medical images, videos, etc.) while in the field. Most of their devices that have been issued to the doctors are newer and they have in the budget to upgrade all devices by end of 2012 but they need to find an adequate connection medium that guarantees speed and portability. Benefits: Faster - More bandwidth using LTE Mobile - More convenience, accessible, and portable. Secure - By using a wireless connection with our existing Virtual Private Network (VPN), we can maximize security. Return on Investment - With this LTE implementation the return on investment would be significantly higher when compared to a wired backbone network.

...18: C 19: C, E 20: A Case Project 1 Using wireless technology the company will benefit financially and will have an increase in productivity of its employees because there is no need to maintain and/or use wired stations (computers, printers, etc.) By this means all buildings will only have a several wireless routers which will most likely cover the whole building. Present wireless standards and types of connections can cover long distances and have faster speeds than wired connections do. Also the company employees will have an access to the company’s network from almost any location inside & outside the company’s building within the access point’s (router) configured signal range. This way the productivity of the company’s employees will increase. Warehouse employees will have the best use of the company’s wireless connection, for example in case of inventory and/or shipping and receiving products, of course this will mean that all of the warehouse employees have some sort of wireless device on hands. All company employees will benefit from wireless networking in case of communicating with each other and/or having access to the company’s network from anywhere within the company’s wireless signal range. Case Project 2 First step in planning the pilot network will be determining how many access points the distribution facility will need, to cover most of its area. Also we will need to determine what type of wireless protocol will be the most efficient to cover the...

...3 in a Series If you’d like to implement Network Access Control, no matter what architecture you select, you definitely want to start by building a small interoperability lab. In this white paper, we’ll give you some advice on what to think about before you get started, and outline what resources you’ll need to have in place in order to begin testing. Any NAC deployment must start by answering three critical questions: 1) What is my access control policy? 2) What are the access methods (such as LAN, wireless, or VPN) I want to protect? 3) How will this integrate with my existing infrastructure? Once you answer these questions, you can begin to gather test lab resources, such as servers (for policy definition points), laptops or desktops (for network access requestors), and switches, access points, and VPN servers (for policy enforcement points). Getting Started with Network Access Control What is my access control policy? NAC is a generic concept that deals with defining access controls based on user authentication, end-point security assessment, and network environmental information. That’s too big for most network managers to bite off in a single chunk, so many NAC deployments hone in on a subset of these goals and expand over time. You’d be wise to do the same---trying to do too much too early in the lifecycle of this emerging group of products will lead to undue frustration and unnecessary complexity. To start, you should define a simple network access control policy...

Having quick access to accurate information can be vital to a sales and marketing department. The sales and marketing department could benefit from using an intranet by being able to look up sales reports, product information, marketing analysis, and researching competitors are just one click away. The human resources department could benefit from having an intranet because they could eliminate using large amounts of paper. The human resources department could upload employee handbooks, benefits information, job listings and applications, newsletters, and new employee interactive training, as well as other information that would save paper costs. The manufacturing and production departments could benefit from using an intranet to help coordinate, maintain, and publish production schedules. The intranet can manage inventory and parts. The company can extend its Intranet into an Extranet which can include customers and suppliers, and enables customers to place orders directly. There are at least two other internet tools that would be helpful to the Dirt Bikes employees. One Internet tool...

...clear up about this topic is when talking about wireless communications we are just not talking about wireless computers networks. Wireless communications also covers wireless phone networks as well as our wireless computer networks. While writing this paper I will try to keep it on just the wireless computer networks, but you will have to keep in mind that this all was started with the telephone and branched out toward computers and other handheld devices. Me like everyone else probably had never really look at wireless as a very vast network which started in 1876 when the phone was invented by Alexander Graham. In 1877, Charles Williams of Somerville Ma had the first private telephone was installed in the home. Four years later over 47,850 telephones were in use in the U.S. (Fowler, 2009). This was the start of the evolution of Wi-Fi, Guglielmo Marconi, an Italian inventor took it a step closer nine years later, and he proved the feasibility of radio communications by sending and receiving the first radio signal. Then in 1869, the first wireless signal across the English Channel was flasher by Marconi. (Fowler, 2009) This should not be confused with the Birth of Telecommunication as some people have linked Telecommunication with wireless communications as John M Shea, an associate Professor of electrical and Computer Engineering from the University of Florida did in an article were he stated in “The History of Wireless Communications” that The first telegraph?

...have better coverage because wireless technology enables the user to communicate while on the go. You don't need extra cables or adaptors to access office networks. Flexibility- Office-based wireless workers can be networked without sitting at dedicated computers, and can continue to do productive work while away from the office. This can lead to new styles of working, such as home working or direct access to corporate data while on customer sites. Cost savings-Wireless networks can be easier and cheaper to install, especially in listed buildings or in apartments. Better opportunities-Wireless networking could allow you to offer new products or services. Most airports, train stations, hotels, cafes and restaurants have installed 'hot spot' wireless networking services to allow mobile users to connect their equipment to their 'home' offices while travelling. Cons: Security- Wireless transmission is more vulnerable to attack by unauthorized users, so you have to have better security. Installation problems- You may suffer interference if others in the same building also use wireless technology or where other sources of radio signals are present. This could lead to poor communication or loss of wireless communication altogether. Coverage- In some buildings getting consistent coverage can be difficult where no signal is available. In structures built using steel reinforcing materials, it may be difficult to pick up a signal. Transmission speeds- Wireless transmission can be slower and...

...Patton-Fuller Community Hospital Networking Project (Week 3) University of Phoenix CMGT 554/IT INFRASTRUCTURE Patton-Fuller Community Hospital Networking Project Today most new building construction is built with new technology and is not as much concerned with the type of budgets that a hospital muse consider in order to redesign a whole new network structure for the purpose of being more optimal and maintaining standards that keep up with advances in new technology. In most cases, a hospital’s network can transition over time with new technology and evolve into meeting the demands it requires to perform effectively. However, upgrading a hospital’s entire network can often be very expensive to implement and sustain. There may be a case where components or parts are no longer being produced to meet current and future demands. In the last several years, changes in healthcare put a demand on hospitals to maintain their networks with new, more efficient solutions that can enhance performance, keep cost low, but most one that is reliable . The Network architecture at Patton-Fuller hospital was designed for each department to rely on information flow between each department. In other words, if the accounting department needed information from the pharmacy or admissions in order to create invoices or insurance billing, it would be rely on those departments to share real time information through the network. It is important for a facility as large as a hospital to have...

...A Look at Wireless Networking Abstract Over the last several years technology has continued to evolve and grow exponentially. The need for wired and wireless networks has become vital in both individuals lives and in the work environment. There are several factors to consider when discussing wired and wireless technologies such as hardware requirements and security measures needed to ensure a secure network. Wireless network trends are now offering new technology such as cloud computing and simply being able to work from anywhere you want. As you read on you will understand the benefits of wireless technology in our personal lives and in work situations. A Look at Wireless Networking Many organizations such as universities, retail centers and your own office depend on the ability to share information in an efficient and useful way. Nowadays networks are an integral part of almost every business and in your own personal life. There are two options for setting up a network — wired and wireless. A wired network uses cables to connect to a computer and a wireless network uses radio frequencies to connect to a computer. The components required to set up a wired or wireless network are somewhat similar with a wireless network needing a few additional pieces. Wireless networks are allowing individuals and businesses to become more mobile. For example, people are able to work from home these days and can have a better work-life balance. Businesses such as Starbucks...
