The Security Of Wireless Networks Essay - 945 Words

Since the inception of IEEE 802.11i in 2004, users and IT administrators have been able to improve the security of their wireless networks by taking advantage of protocols like CCMP, an algorithm designed to provide both authentication and encryption. With CCMP, wireless networks can be secured with 128-bit AES encryption, provided by the Counter Mode component of CCMP. The CBC-MAC mode component provides the authentication mechanism. Although the security provided by 802.11i is a significant improvement to 802.11 networks, the security only applies to the data frames and does not provide any security over the management frames. In an 802.11 network, the data frame is what carries the protocols and data from higher layers. For example, a data frame might contain a JPEG image or JavaScript from a web page that the user is browsing. Whereas, 802.11 management frames allow the WiFi stations to establish and maintain communications. For example, the management frames might carry co nfiguration information about the type of wireless device that’s in use on the network, as well as its configurations. Since management frames are unencrypted and can reveal critical pieces of information to a hacker, such as details about the types of wireless devices on the network as well as its configurations, it’s important to be aware of the different types of wireless attacks that a hacker can carry out against your wireless network.

Wireless networks are many and diverse but are frequently categorized into three groups based on their coverage range: Wireless Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area Network (WPAN )and etc. WWAN includes wide coverage area technologies such as 2G cellular, CellularRead MoreWireless Network Security1602 Words   |  7 PagesPaper CNT4514 Wireless Vulnerabilities The world of wireless networks as we all know is one of the most rapidly growing areas in our world today. With the massive amount of data that is going on, â€Å"the cloud† the security of all of our data is questioned. As well with so many of our day to day tasks relying on our wireless capabilities it make you wonder how safe is it to rely so heavily on something.

This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in Metcalfs law. Metcalfs law states that if you connect any number, n, of machines - whether computers, phones or even cars - and you get n squared potential value.[1] The incredible growth of the Internet seems to validate Metcalfs law. It thenRead MoreWireless Network Security ( Cs6526 / Fall 2014 )969 Words   |  4 PagesWIRELESS NETWORK SECURITY (CS6526/FALL 2014) ASSIGNMENT # 2 NAME: VIDYA PANGA NET ID: KS9877 1. What are the security requirements and challenges of MANETs? Answer: MANETs (Mobile ad-hoc network) is defined as autonomous collection of wireless mobile nodes that are self-configure to construct a network that can communicate over relatively bandwidth constrained wireless links. In MANETs the security depends on the several parameters are as follows: Authentication: It enables the mobile nodes to ensure
