Wireless LAN Security

Fundamental Premise
Security cannot be considered in isolation and to be effective must consider the entire system
That is, network and LAN security must be:
Consistent with other security mechanisms
E.g. application, data, hardware, and physical
Supportive of other security mechanisms
Specific LAN Threats
Availability
Worms/Virus DoS
Errant applications creating lots of traffic/malformed traffic
Authentication
Spying devices on LAN
For example, a contractor connecting to LAN
Secrecy
Sniffers being connected to the LAN to collect passwords, etc.
Current State of LAN Authentication
Usually none!
If in the building can plug in to the LAN
Can cause severe problems:
Using LAN for illegal purposes (company/person may be liable)
Can more easily compromise servers
For example, send spam from your mail servers
Wireless LANs are bringing issue out
Summary
Wireless LAN Security is not independent of the greater network security and system security
Threats to the Wireless LAN are largely in terms of being available and in providing a means to attack systems on the network
That is, not many folks attack routers (yet)
