Changing your default settings on your network offers only minimal actual
security. The upside to changing default settings, however, is the appearance.
Much like the security gates set up by the doors of stores, changing default
settings can be a visual deterrent to wardrivers—it gives the appearance of
knowing what you’re doing. While some wardrivers might not be scared off,
changing the default settings is worth the effort.
MAC Addresses
You can limit the computers that can access your network by using MAC (Media
Access Control) addresses. Every piece of networking hardware, including
wireless hardware, comes with its own individual MAC address. Many routers will
allow you to limit access to certain MAC addresses. If the router does not
recognize the MAC address, it will not allow that computer access. This will
foil all but the most accomplished hackers. Using MAC address filtration is
different for each router, so consult your instructions or call the
manufacturer for assistance.
Firewalls
Firewalls examine information coming from or going to the internet and
filter out any of the “bad” stuff. Software, hardware, and wireless firewalls
are available. Consider placing a firewall on every computer as well as your
wireless access point.
Additional Protective Measures
Here are a few additional suggestions that will add to the security of your
computer:
Avoid saving personal
information—such as passwords, credit card and social security numbers,
and financial records—on your computer or network.
Invest in antivirus and
antispyware programs.
Keep your programs,
especially security tools, current using Automatic Updates.
Place your wireless access
point away from windows. Putting it in a central location in your home or
business will help decrease signal strength outside of the intended
service area.
