Master the basics in designing, building, and managing a Cisco Aironet WLAN. 802.11 Wireless LAN Fundamentals gives networking engineers and IT professionals the knowledge they need to design, deploy, manage, and troubleshoot their own wireless local-area networks (WLANs). Starting with an overview of the technology and architecture of WLANs, the book goes on to explain services and advanced features that such applications can provide. Most importantly, it provides practical design guidance and deployment recommendations. |

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. |

802.11a Wireless Security Threats and Mechanisms

High bandwidth wireless local area networks are gaining popularity. Along with this
popularity has come a well publicized series of vulnerabilities in the IEEE standard
implementations. In response, a number of standards from wired networking (e.g. 802.1x
and IPsec) are being adopted to wireless. Vendors are also developing and selling
proprietary security solutions. The normal security risk assessment/risk mitigation
process can be complicated by a misunderstanding of the range of available options and
the strengths and weaknesses of each. However, the nature of wireless technology raises
the stakes in performing a proper risk assessment and deploying a wireless network that
meets local security requirements.
This white paper first describes taxonomy of wireless LAN attack techniques. We then
describe the generic mechanisms available for authentication of users and the protection
of the privacy and integrity of the data. We conduct a basic analysis of each security
countermeasure by looking at the attack techniques addressed by the mechanism. Our
analysis takes into account the perspective of both insiders and outsiders. We conclude
by stating our recommendations for WLANs. These recommendations include:
· Mutual Authentication
· Layer two encrypted tunnel
· Strong cryptographic integrity verification
Without these features, not only is a WLAN vulnerable, but the entire information
infrastructure of which it is a part is at risk. We also recommend per-packet
authentication although we would not go so far as to make it a requireme nt. |
