[PEN-TEST] Penetrating Wireless Networks

Greetings,

I know the technologies are rather new compared to wired networks,
but does anyone have and pointers for penetration tests of wireless
networks, 802.11b in particular?

In my opinion, with the advance of wireless networks, this will be a
very important part of pen tests. Has anyone developed any
methodologies for such tests? Are there any tools available that
assist in testing wireless networks? For example, one is able to run
tcpdump and other goodies on the wireless card just like on regular
NIC's. However, in order to gain access to the WLAN, one must know
not only the WEP encryption key (if WEP is used), but also the ESS
(network identifier), preamble length, and channel number. Are there
any tools that provide automation of changes for these values (for an
automated scan)? Are there any tools for 'low-level' 802.11b data
examination (i.e. preamble checking/display, etc)?

Regards,
Frank
