Community Wireless: Security
Wireless LAN Hunts Go Airborne ( July 29, 2002 )
Hobbyist wireless LAN sniffers are now taking their war-driving
skills to the air, detecting hundreds of WLAN access points during
short trips in private planes cruising at altitudes between 1500
and 2500 feet. A Perth, Australia-based "war flier" recently
managed to pick up e-mails and Internet Relay Chat conversations
from an altitude of 1500 feet.
Solutions Improve Security of Wireless LAN's,

The solutions provide for Wired Equivalent Privacy (WEP) key
rotation and the robust detection of rogue access points anywhere
on an organization's wireless LAN.
honypots a new hacker trap:
( July 30, 2002 )
Last month researchers at the government contractor Science
Applications International Corporation (SAIC) launched what might
be the first organized wireless honeypot, designed to tempt unwary
Wi-Fi hackers and bandwidth borrowers and gather data on their
techniques and tools of choice.
and Protecting 802.11b Wireless
( Sept 4, 2001 )
How many network administrators do you think would allow a
complete stranger to walk into their wiring closet and plug in
their notebook to their company's network? Not too many, I
suspect. But that's what's happening to companies coast-to-coast.
Well, not exactly. Strangers aren't plugging into networks, but
they are attaching to networks using 802.11b wireless network
cards, and that's essentially the same thing.
- Port Based Network Access
Establishes a means for user authentication. 802.1x relies on
certificates to identify people, authorize them to access various
Wi-Fi networks, and let them travel seamlessly between one and the
next. This supplement to ISO/IEC 15802-3:1998 (IEEE Std
802.1D-1998) defines the changes necessary to the operation of a
MAC Bridge in order to provide Port based network access control
Temproal Key Integrity Protocol (TKIP ) ( Febuary 1, 2002
Will concernof the inherent vulnerability of wireless and
inadequate security measures erode consumer confidence in wireless
LANs? Not if the WECA and IEEE can stop it.
