Secure Wireless: What Vendors Dont Tell You
As a security-conscious network manager, you've listened to vendors when installing their new wireless LAN products. With 128-bit WEP for data encryption and 802.1x and LEAP for authenticating any user accessing the network, you're confident about your network security and sleep fairly well at night. That's fairly well.

Stateful User Security in Wireless LANs
Why are firewalls important in the wireless world? Even after strong encryption has been used and authentication has been successful, wireless users should still be treated less trusted than wired users. Wired users have a physical location that can be easily traced, since they sit at the end of a cable. There is no such principle in a wireless network. A user could be in the parking lot, using a stolen laptop with a stolen password.

WLAN (Wireless LAN) Whitepaper
The latest WLAN specification, 802.1x, provides a roadmap for implementing improved WLAN security. Not surprisingly, an authentication server - long a cornerstone of remote access security - plays a pivotal role in securing an 802.1x WLAN. And, new 802.1 x security methods provide strong authentication and data privacy techniques to fully secure WLAN access. This paper: Outlines the specific issues which characterize WLAN security, and describes how 802.1x addresses them, describes the role of an authentication server and 802.1x security methods in securing WLANs, and demonstrates some tools out in the wild that are available for use on WLANs.

Wireless Security Starts at the Endpoint
Offering convenience and ease of use that have revolutionized the way people use computers and networks, wireless networks have also complicated endpoint management and security. Wireless networks have earned a reputation for being difficult to monitor and administer, exposing organizations to a higher rate of infection from Trojans and viruses and incurring greater support costs than anticipated.

Security Vulnerabilities and Wireless LAN Technology
This paper describes many of the vulnerabilities that can exist for home wireless LAN systems, also referred to as small office/home office (SOHO) LAN systems, as well as for enterprise LAN systems. Both LAN types are vulnerable to the same kinds of attacks and errors, but this paper places the emphasis on details of the larger more complex enterprise wireless LANs.

Implementing a Secure Wireless Network for a Windows Environment
The goal of this paper is to be an easy to follow guide for configuring and securing a wireless network in a windows environment. Specifically we will look at configuring Microsoft Internet Security and Acceleration (ISA) Server 2004, Microsoft Certificate Services Server, Microsoft Internet Authentication Service, various off-the-shelf wireless access points, and the steps involved for configuring a VPN for connecting wireless clients as part of a defense-in-depth approach to 802.11 wireless networking.
