Essay about Wireless Network Security

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

Wireless Routers is a wireless local area network (WLAN) that determine the next route of the packet should travel to the destination (Rouse, 2005). It converts the internet connection that was received from phone lines into radio signals and brings convenience to the portability devices that has built-in network card to gain the radio signals to get to the Internet connection (Switcher, 2015). Table 2 refers to the comparison of three models of wireless router.

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

4. Use the Internet to research one to two applications of the identified wireless technology. List each application found. Reference the websites you used to locate this information.

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

your response to the following: Imagine you are the network administrator of aWLAN. Give an example of how knowing the 10’s and 3’s Rules of RF Math can helpyou on the job. Include your answers to Case Project 3-5 in your response. Show your work

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

Wireless connectivity is critical to most homes and corporations as the world advances in technology. The technology has grown to a capacity that allows for extreme growth in wireless infrastructure as well as a trend of bringing your own technology device. Many corporations experience a high volume of critically important information being transferred over it wireless network so security is essential. There are many differences between a home and corporate wireless installation and each has its differences in securing.

Shared bandwidth – all wireless devices compete for available bandwidth. As the number of wireless nodes increase, the bandwidth can be reduced, which decreases the performance of the network.

IEEE802.11n made numerous changes to the 802.11 wireless standards that greatly increased the throughput as compared to earlier versions. 802.11n uses MIMO which is Multiple Input Multiple Output (also known as Multiple Antennas). MIMO makes use of multiple antennae to create multiple streams of communications between a transmitter and a receiver. The 802.11n amendment also introduced changes in the physical as well as MAC layers to make marked changes in the effectiveness of wireless networks. These changes included spatial-division multiplexing, space-time block coding, and transmitter beamforming.

This report fulfills the specific requirement for documentation as specified in FIT 5083 Assignment 1. In this technical report, we will identify the various steps and techniques used in deployment of wireless network. Initially, what is networking or network infrastructure? Networking mean to connect two or more devices and configure them in such a way that they can communicate with each other. In networking, network infrastructure means to connect the software and hardware part rather than actual connection between two devices. Now days, wireless network connections are highly on demand because it’s easy to access and it does not require any cabling structure.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.
