Wireless Security Workshop

  • Security Protocols for Wireless : WEP (no documented cases of WEP being cracked in the “wild”), LEAP, TKIP, Broadcast Key Rotation, VPN, etc. How to use these protocols to make wireless secure. Other wireless security options, WPA/802.11i, 802.1x (EAP TLS, EAP-TTLS, PEAP).
  • Configurations for highly secure wireless systems : SSIDs. Hiding your wireless network? Hardening wireless access points (WAPs). Securing WAPs against theft.
  • War Driving : Is it a problem? How to protect yourself from War Driving? Should you be worried if someone can map your network?
  • Traffic Sniffing : Is WEP really secure? How does encryption (e.g. SSL/SSH, VPN, etc.) help and hinder sniffing and management? Can antenna type help prevent others from sniffing? Can controlling the radios power output help?
  • Rogue Access Points : How do I find them? Are they a problem? Ad hoc (peer to peer) mode. Competition to route traffic between access points. Policy issues around Rogue Access Points. Frequency selection coordination.
  • Being a good neighbor : Interference with and from neighboring wireless systems. Frequency selection. Antenna placement and types. The uneducated neighbor.
  • Wireless security tools : What tools are available to make it easier to secure wireless systems (e.g.AirMagnet, AiroPeek, AirSnort, Ethereal, Kismet, NetStumbler, WEPCrack, etc)? Or maybe they don’t make it easier. Commercial approaches to enterprise WAP security (e.g. ReefEdge). Intrusion Detections Systems that may allow you to detect when someone has gotten around your security.
  • Future network protocols : How might things like IPv6 and IP Multicasting work over wireless networks? Are there any problems? 802.11i/WPA2 with AES require new hardware for implementation.
  • Proprietary implementations : 108 mb G+, Turbo etc. (channel doubling and the problems that come with it).
  • Issues with mixed B/G Networks : B clients slow down G networks. 54 mb G has smaller coverage area then B networks.
  • Capacity Planning : Is what makes sense today going to have legs for the future. Critical issues if you have to adjust capacity by adding access points.
  • User training : Network Staff, Help Desk, End Users, both with regards to how to configure and use the wireless network as well as security issues.
  • Physical Security : Training Security staff to recognize suspicious activity as it relates to the wireless and wired network.
