Download or read book Enhancing Wireless Network Security IEEE 802 1x written by Haider Waheeb Qleibo and published by . This book was released on 2002 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Local Area Networks (WLANs), widely prevalent in corporate environments, is a current giant leap in information technology. This new paradigm of communications has leverage over other ways of data transmission, because it enables businesses and corporate environments to operate in a fast, better and more profitable way. Through the use of always-on, always-connected and always-available content and applications, WLAN combines data connectivity with user mobility. The IEEE standard for wireless LAN is 802.11. The 802.11 is emerging as a significant aspect of Internetworking. Growing rapidly in the wireless local area network environment, 802.11s are easy to find, because wireless technology allows the network to go where wire cannot. This fact, however, raises a number of security concerns. The current security solutions offered on a private 802.11 network in a public setting are not sufficient to protect sensitive material, so other measures are needed to provide adequate protection for data passed over the air. Although encryption, authentication and authorization are the pillars of security, there are other techniques that can be used and implemented for network defense. Security concerns have evolved, because there are limitations and weaknesses in controlling access and there are flaws and vulnerabilities in WEP data encryption. These things add to the insecure nature of radio broadcast transmission. This study discusses some security models offered over wireless networks and integrates the security enhancement by combining some of the wired techniques such as adding Kerberos to the wireless security equation along with RADIUS for increased authentication and authorization so that compromising the network is a non-trivial task. Those models are designed to prevent unauthorized access to the network from outside the wireless network environment. While we can make intrusion difficult, we cannot prevent hackers with portable devices and scanners from intercepting data and gaining access to the network. If we want flexibility and mobility, we can have this, but not with total security. The 802.11 technology protection is not failsafe as long as there is technology that allows portable computing devices with scanners to gain access to the LAN or intercept data.

Download or read book Guide to Wireless Network Security written by John R. Vacca and published by Springer. This book was released on 2016-04-01 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. INTRODUCTION With the increasing deployment of wireless networks (802. 11 architecture) in enterprise environments, IT enterprises are working to implement security mechanisms that are equivalent to those existing today for wire-based networks. An important aspect of this is the need to provide secure access to the network for valid users. Existing wired network jacks are located inside buildings already secured from unauthorized access through the use of keys, badge access, and so forth. A user must gain physical access to the building in order to plug a client computer into a network jack. In contrast, a wireless access point (AP) may be accessed from off the premises if the signal is detectable (for instance, from a parking lot adjacent to the building). Thus, wireless networks require secure access to the AP and the ability to isolate the AP from the internal private network prior to user authentication into the network domain. Furthermore, as enterprises strive to provide better availability of mission-critical wireless data, they also face the challenge of maintaining that data's security and integrity. While each connection with a client, a supplier or a enterprise partner can improve responsiveness and efficiency, it also increases the vulnerability of enterprise wireless data to attack. In such an environment, wireless network security is becoming more important every day. Also, with the growing reliance on e-commerce, wireless network-based services and the Internet, enterprises are faced with an ever-increasing responsibility to protect their systems from attack.

Download or read book 802 1X Port Based Authentication written by Edwin Lyle Brown and published by CRC Press. This book was released on 2006-12-19 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Port-based authentication is a "network access control" concept in which a particular device is evaluated before being permitted to communicate with other devices located on the network. 802.1X Port-Based Authentication examines how this concept can be applied and the effects of its application to the majority of computer networks in existence today. 802.1X is a standard that extends the Extensible Authentication Protocol (EAP) over a Local Area Network (LAN) through a process called Extensible Authentication Protocol Over LANs (EAPOL). The text presents an introductory overview of port-based authentication including a description of 802.1X port-based authentication, a history of the standard and the technical documents published, and details of the connections among the three network components. It focuses on the technical aspect of 802.1X and the related protocols and components involved in implementing it in a network. The book provides an in-depth discussion of technology, design, and implementation with a specific focus on Cisco devices. Including examples derived from the 802.1X implementation, it also addresses troubleshooting issues in a Cisco environment. Each chapter contains a subject overview. Incorporating theoretical and practical approaches, 802.1X Port-Based Authentication seeks to define this complex concept in accessible terms. It explores various applications to today's computer networks using this particular network protocol.

Available in PDF, EPUB and Kindle. Book excerpt: As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology. Designed with the system administrator or serious home user in mind, it's a no-nonsense guide for setting up 802.11 on Windows and Linux. Among the wide range of topics covered are discussions on: deployment considerations network monitoring and performance tuning wireless security issues how to use and select access points network monitoring essentials wireless card configuration security issues unique to wireless networks With wireless technology, the advantages to its users are indeed plentiful. Companies no longer have to deal with the hassle and expense of wiring buildings, and households with several computers can avoid fights over who's online. And now, with 802.11 Wireless Networks: The Definitive Guide, 2nd Edition, you can integrate wireless technology into your current infrastructure with the utmost confidence.
