A quick Google search on
wardriving yields thousands of sites detailing how a person can detect
wireless networks. Free software tools like
netstumbler make
it extremely simple for a layman to map and make use of open wireless
networks. Though the majority of those engaging in this activity are
harmless, leaving a wireless network accessible is akin to leaving your
front door open.
What's worse, a malicious network
intruder looks to the outside world like you. It's as if someone
co-opts your street address for whatever nefarious purpose they have in
mind. If the intruder engages in illegal activity, your ISP has no way of
knowing if it's you or the intruder that's responsible. Several ISPs will
suspend the accounts of people engaging in illegal activity, such as
running file-sharing programs, distributing pornography, or running an
internet server.
DCNS can help to secure your wireless
infrastructure from unwanted intruders. If you aren't a networking guru,
or are uncomfortable with computer technology, or just want to be sure, a
security audit can show you what needs to be done to secure your wireless
network.
Security should fit the task at hand. Few
would consider using a bank-vault door in their house because of the
expense involved. Similarly, enterprise-class security is overkill for the
majority of homes and some small businesses.

measures for what DCNS can do to achieve the minimum level of acceptable
security. If you are running a business that depends on sensitive data, or
a business where a network intruder could gain financially or cause
serious damage, see stronger security measures.
