The ten minute guide to wireless security, part one

Wireless local area networks (WLANs) are not like wired ones ? data is highly vulnerable in its silent transit through the air. All that is needed is the right utility to find the radio signal, interpret the data stream in much the same way as would any other network interface, and direct the intruder to useful bits of plain text information. Using an unsecured wirless link is the technological equivalent of leaving confidential documents lying around in the street.

Never underestimate what is worth stealing. There can?t be a single wireless network that doesn?t send emails, invoices and online banking log-ins from time to time, so there can?t, by definition, be a wireless network that somehow doesn?t need securing.

The topic is a big one, but here are a few basic pointers for using ?informal? (ie non-corporate) wireless networking. Techworld.com - The ten-minute guide to wireless security - part one
