Chapter 8 -
War-Driving and Identity Theft
If one wants to make their WLAN SSID include
their name, the person war-driving through the neighborhood can
easily use a phone book and find the individualís house as well as
steal their wireless network. This SSID is also one of the pieces
of information that is usually broadcast by a wireless network
system. Some configuration utilities will let users configure the
wireless router to not broadcast the name.
Another setting that can be overlooked is
encryption. By default, many times encryption is disabled, which
means that any communication between that computer and the wireless
access point can be sniffed by anyone within range of the system.
Additionally, anyone close enough to the wireless system is capable
of using that individualís Internet connection to cause trouble.
This could land the victim in a heap of trouble when a crime is
investigated and the evidence points to that individualís system.
Figure 8.3 - Wireless Encryption Settings
Figure 8.3 above shows a configuration screen
where the encryption setting is made. This example shows that for
this system, the choices are: Disabled; 64 bits; and 128 bits.
Disabled offers no protection against hackers, 64 bits provides
medium protection and 128 bits is the highest level of protection.
There is, however, a performance impact
involved with higher levels of protection. This is because
encryption requires the computer do a bit of additional work to code
the transmissions before sending them over the network. This
performance impact is generally fairly minor, but if performance is
critical, one may prefer to use physical network cables or a lower
level of encryption.
