Wireless LAN Security
All the normal Internet issues and more
Open WLANs are everywhere
Vendor defaults are usually open
Many types of attacks
Attackers can be miles away
Access, Authentication, Accounting
Beacon Frames
Closed networks do not advertise
Good 802.11b sniffers can pick up the SSID (network name) anyways
MAC Address Filtering
Static list or high end units via Radius server
Trivial to clone an allowed MAC address
Shared Password
No individual responsibility
Lost key, every device must be changed
Can be sniffed with some luck
WEP Key
Shared password problems from above
Can be broken with some effort
Securing Data
Common Types of Attacks
Man in the middle
Authentication forging
Rogue access points
Brute force attack
Too Many to be Safe!
Mitigation is the Best Policy
