A group of researchers from Rice University and AT&T Labs have used off-the-shelf methods to carry out an attack on a known wireless encryption flaw — to prove that it “could work in the real world.” Via [cnn.com]… Continue Reading

Cipher Attack Delivers Heavy Blow To WLAN Security
A new report dashes any remaining illusions that 802.11-based (Wi-Fi) wireless local-area networks are in any way secure. The paper, written by three of the world’s foremost cryptographers, describes a devastating attack on the RC4 cipher, on which the WLAN wired-equivalent privacy (WEP) encryption scheme is based.

Basic Security Mechanisms for Wireless Networks
As more companies start to deploy wireless networking, important security aspects are often overlooked. Wireless networking was initially marketed towards home consumers and specialized applications, but was limited by low throughput speeds. As the technology matured, networking standards were introduced to ensure interoperability between vendors, and greater speeds were obtained. Driven by both the demands… Continue Reading
The War Over 802.11x Security
Not long ago, when wireless networking was new and rare, security was an afterthought. The reason? The scarcity of 802.11b cards acted as a form of back-handed security. If no one had an 802.11b card, outsiders couldn’t very well scan your setup, right? Now, however, that’s changed. Wireless gear is readily available–and cheap–so that almost… Continue Reading
