Security Basics: RE: jamming or blocking WLAN

["Andy Cuff (Talisker)" <SecurityLists () securitywizardry com>]

Hi Adam,
I'd suggest that you approach jamming wireless with care, as it's certainly
illegal in the UK and I suspect many other countries

There are a number of products out there which will detect rogue Access
Points, with reference to securing wireless in general, Matt Byrne's
wirelessdefence.org note (Defence is spelt in English not American) is a
great resource http://wirelessdefence.org/ 

We have details of the various Wireless Intrusion Detection Systems here
