Advantages And Disadvantages Of IEEE 802.11

One of the very good utilities of the hospitals network is the availability of the wireless access on the ward level, this will insure instant connectivity to the hospitals network from the small mobile devices such as laptops or other Wi-Fi based medical devices such as the new cardiograph devices which shares data with the database servers through wireless connection. These wireless devices depending on the diagram specifications are in 5 gigahertz frequency which are not compatible with every laptop computer, a recommendation to replace them with 2.4 gigahertz frequency devices are more efficient in order to allow laptops to access the network. A special attention is needed in the security of these wireless access points by connecting them to a server like RAS server to authenticate the personnel accessing the network wirelessly before allowing the devices to use the network. This is very important practice to prevent a destructive intrusion into the network.

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

Drastic times called for drastic measures during the times of the Great Depression. The longest and most severe depression had major negative effects on unemployment rates, living conditions, health, education, families, and the overall quality of life during the time. In response to all the adversity, the New Deal allowed one of the most ambitious agencies, the WPA, or the Works Progress Administration, to be implemented. The WPA lead to major improvements in social and cultural aspects, large developments for the state of Kentucky and the effects of the WPA were everlasting and can still be seen today.

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

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.

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.

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

The DoS attack can only obtain little amount of unauthorized data as the attack interrupts the networks which prevents the traffic flow and indirectly prevents the data from being accessed. The actual reason for using a DoS attack is to gain the recovery of wireless network, at this moment all

Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC 's up and running is illustrated with applications.

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
