offering the advantage that LAN connections can be made freely within
the range of the radio waves.
On the other hand, the radio waves reach all points within this range,
regardless of walls or other obstacles, possibly resulting in the problems

Malicious third parties may purposely intercept the radio waves and
steal information contained in the transmissions, including such
personal information as ID numbers, passwords, credit card numbers,
e-mail messages, etc.
• • • • Improper intrusions
Malicious third parties may without permission access the personal or
company network and steal personal or confidential information,
pretend to be someone else and leak incorrect information, rewrite
information that has been intercepted, introduce computer viruses or
otherwise damage data or the system, etc.
Wireless LAN cards and wireless access points generally include security
