802.11 Case Study

In Extensible Authentication Protocol, a random set of authentication mechanism is used such as using smart cards or certificates or using user’s credentials. Primarily the WLAN uses EAP for the purpose of passing messages during the authentication process.

Authentication: 802.11 defines authentication services to control LAN access to a level equal to a wired link because wireless LANs have limited physical security to prevent unauthorized access. Every station, whether part of an independent BSS or an ESS network, have to use the authentication service prior to establishing a connection with another station with which it wishes

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

The WPA2-Enterprise mode provides the security needed for wireless networks in business environments. Though more complicated to set up, it offers individualized and centralized control over access to your Wi-Fi network. Users are assigned login credentials they must present when connecting to the network, which can be modified or revoked by administrators at any time.

Should Wi-Fi technology in the 21st century be kept from the wild? In The Atlantic article “Wifi in the Woods” by Jason Mark, the internet is difficult for people to get away from. Mark discusses that a group of people travelling to the tundra, including DJ Spooky (a record producer), adapted to their environment, when they encountered a loss of internet signal. He also explained that companies are laying out plans to add internet to wild country. Furthermore, he discusses the pros like checking weather information and global connectivity, and the cons like no escaping from government oppressors and losing the calmness of the wood. Wifi technology is of more positive development in rustic

802.11 WLANs use CSMA/CA, the devices use a four-way handshake to gain access to the airwaves to ensure collision avoidance, and also to know about hidden nodes from different wireless standard.

These initiatives were intended to be cost-shared and localities were required to contribute rights-of-way. The law also required that the Secretary of the Interior be consulted regarding plans that affect reclamation, irrigation, or public lands controlled by the Department of the Interior. Congress amended the WPFPA in 1956 to give Congress greater control over large flood control

A wireless computer can "roam" from one access point to another, with the software and hardware maintaining a steady network connection by monitoring the signal strength from in-range access points and locking on to the one with the best quality. Usually this is completely transparent to the user; they are not aware that a different access point is being used from area to area. Some access point configurations require security authentication when swapping access points, usually in the form of a password dialog box.

The first version of the 802.11 protocol was released in 1997, and was updated to 802.11b in 1999 to permit 11 megabits to be transmitted. But Wireless WANs (WWANs) network cover broader areas then WLANS and includes such things as cellular networks, cellular digital packet data, satellite networks, microwave networks, and much more. But Both WWANS and WLANs rely on the RF spectrum as there communication medium. The security measure for wireless users is strict, even though it can be accessed by walking near a building. Wireless signals are easy too pickup especially with a cellular device but it is usually password but still can access from intruders. But there are many way of preventing these hackers from entering in which will be explained later. Also for Mobile network/and its network security, its network operates on a radio frequency consisting of radio cells, each served by a fixed transmitter, and for both wireless and mobile networks, they have the advantage of mobility, flexibility, ease of installation, and low cost. But some drawbacks for both systems include Limited Throughput, Limited Range, in building penetration problems, vulnerability, and lastly security.

Wi-Fi can be found anywhere in this day in age, you can walk into almost any establishment and you’ll be sure to find their Wi-Fi, accessible from anywhere within their spaces. Each data packet being transmitted through the air, whether containing private, sensitive or insensitive information, is available for an attacker to capture. To fight against this, there have been some standards that have come out through the years to guard and protect data, such as WPA. All standards have been created to replace the preceding one due to vulnerabilities found in the engineering of them. Still to this day, not every standard is fully secure, attackers still find

IEEE 802.11 commonly known as Wi-Fi is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in various frequency bands such as 2, 3, 3.6, 5 and 60 GHz.

Focusing onto the WLAN Notions and Constituents, we already have got the basic idea on the wireless devices. Ranging from notebooks to smart phones, each and every device has got an in-built wireless card slot. It enables the gadget to be able to operate on a WLAN wiring consideration. In certain instances, enterprises and organizations are set up in search a way that the host is not directly attached to the device being used (Janevski, 2003). It is often stationed at a particular place in the office and from it, data can be transmitted to

In the world of IT, there are many pioneers that helped contribute to the way we use technology today, from early ideas of what a computer could be way before one was actually made, to the inventor of Wi-Fi signals. In this report I will be discussing 6 of them and evaluating which is the ‘top pioneer’.

But still there were many flaws that intruders used to take advantage and used the flaws for their own advantage thus making WPA also vulnerable. WPA2 was introduced to overcome the flaws that WPA had in it. WPA2 uses AES (Advanced Encryption Standard) algorithm to provide security thus making it very difficult for intruders to break the security of this layer. As the algorithm encrypts secret and confidential data and it’s very difficult for the intruders to decrypt it. The issue with WPA2 security is that as it has complex encryption thus it requires a lot of processing power so the old systems which do not have the capability to process a lot of computation thus WPA2 is not suitable for the old deployed systems.

In the last few years, number of mobile users/wireless users has been increased explosively all over the world. The demands for wireless communication network has been increased day by day and it cannot be satisfied with wired networks because it has been seen that communication channels are more contaminated than wired networks. The main characteristics of the wireless communication are the multipath reception. We can receive signal not only through Line of Sight but also reception can be made through a large number of reflected radio waves that arrive at the receiver at different times. The difference in arrival time is caused due to trees, vehicles, buildings, rocks etc.
