Hiya

As for the Security side of things, wireless LANS have put the security
of the web back by 10 years, i mean they are a joke.
it seems that a large amount of companies that i do pen-tests for seem
to have a set of rogue tech support departments that setup these
wireless lans and then dont bother to tell anyone (hell we all know its
cool walking around without any cables)
the problem being that is there is no or little encryption used and also
no ACL's to only allow certain mac's to connect (yeah i know that MAC
address's can be changed and spoofed)
im hoping to have a quick paper type of thing written soon with some
recommendations on securing a wireless setup , so ill post it to the
list if anyone is interested

as for equipment, at the mo im using the cisco aironet base and cards
(mainly coz they work so goddam well with fbsd)
