Network Basics NETWORKS Wireless security Wireless networks are inherently less secure than wired ones. In a wired environment an intruder needs to gain physical access to your network wiring to break into your network; in a wireless environment, he just needs to be in range of the radio waves that carry the network traffic. Since these waves penetrate building walls and easily carry for tens of meters, an intruder sitting in a car in your parking lot could monitor the traffic on the wireless LAN in your building. To frustrate intruders, a number of standards have been developed to make security for a wireless network more-or-less equivalent to that of wired networks. These standards work in three areas: Network name (SSID): A network name, or service set identifier (SSID) is an alphanumeric character string that provides basic access control on a wireless network.

security
Wireless networks are
inherently less secure than
wired ones. In a wired
environment an intruder
needs to gain physical
access to your network
wiring to break into your
network; in a wireless
environment, he just needs
to be in range of the radio
waves that carry the
network traffic. Since these
waves penetrate building
walls and easily carry for
tens of meters, an intruder
sitting in a car in your
parking lot could monitor
the traffic on the wireless
LAN in your building.
To frustrate intruders, a
number of standards have
been developed to make
security for a wireless
network more-or-less
equivalent to that of wired
networks. These standards
work in three areas:
Network name (SSID):
A network name, or service
set identifier (SSID) is an
alphanumeric character
string that provides basic
access control on a wireless
