Chapter 9 - Self Protection on the Web
Another setting that can provide an additional
level of protection that frequently gets overlooked is encryption.
There are many ways to implement encryption. The most common use is
to take regular communications such as email or chat sessions and
change them into a coded message. Without the appropriate
encryption code, that coded message would appear to be gibberish to
any other person or program.
Users should be aware that many times
encryption is disabled in wireless networks by default. This means
that any communication between that computer and the wireless access
point can be sniffed by anyone within range of the system.
Additionally, anyone that is close enough to the wireless system is
capable of using its Internet connection. Once hackers tap into
that wireless network, they can commit a variety of cybercrimes.
This could land the computer owner in a heap of trouble when a crime
is investigated and the evidence points to their system.
Rewards of Wireless Communications
The benefits of wireless are seen regularly in
advertisements that tout the benefits of mobility. The ability to
work using a laptop and wireless card wherever a computer is needed
is the scenario that is promised. The reality is that a person can
still be more productive in their office than they are in the
airport waiting for a flight, if there is no wireless access at the
airport. The places with wireless connections available are
generally places where people congregate like coffee shops, bus or
train terminals, and airports. Some are paid services and some are
Corporations that enjoy name recognition often
sponsor free services. In some cases, a company provides free
access in certain places to gain name recognition. As an example of
this, hotZona, LLC, a company in Arizona provides free wireless
access to the Arizona State Legislature. This coverage is free,
even for visitors to the facility. It is provided with Cox
Communications and Intel.
