Despite the best efforts of developers and standards bodies, wireless LANs (WLANs) are still the poster child for unsecured networks. Wireless network-security protocols contain enormous loopholes, coverage areas leak like a broken faucet, and many administrators do not even bother to turn on the security features that come with their systems.
