Security Concerns

Mobile wireless devices have the same problems with the wired equivalent
protocol (WEP) in 802.11b as does any wireless workstation. Security
is lacking in WEP-based security keys, especially when the values are
kept the same for a period of time. This means that even a PDA can give
up its secrets for accessing the network because hackers need only capture
a few packets to descramble the rest of the security code that permits
access into your network.
Understanding the similarities and differences when dealing with security
in your wireless environment is important, because it can help you
deal with the vulnerabilities in your wired network. When a hacker accesses
internal resources over your wireless connection, your wired Ethernetwork
is vulnerable to attack at any server as well as any access point.
