Steps you can take to protect your wireless network:

There are a number of very simple steps you can take to protect your
wireless network. For many of these, you will have to access your router
configuration utility (check your manual on how to do this, you will
generally need to type an IP address into your browser such as 192.168.0.1
or 192.168.1.1).

Don't broadcast your SSID. If you are broadcasting your SSID, this is the
first thing a program will pickup and recognize. If you configure your
router to not broadcast your SSID, it will be difficult to detect (but not
impossible, for some software can sniff wireless communication, so if you
are using your wireless network, the SSID can be revealed). If you are not
broadcasting your SSID, but it can be guessed (such as if you are using a
default SSID), cloaking is pointless. Due to this, remember to change your
SSID from the factory default. This is not a 100 percent effective method
to secure your network, but it is a good first line of defense.

Change the default password. When you buy a router, a factory password is
stored. People experienced in working with routers know the default
passwords for different routers (and the make of the router can be seen by
software such as netstumbler). It is important that you secure
your router with a good password.

Encrypt your wireless communication. I can't stress the importance of
encrypting your wireless communication enough. Enable encryption and enter
a key. Most routers are only capable of WEP encryption, but if they permit,
use EAP encryption, it's more secure than WEP. Like cloaking your SSID,
encryption is not 100 percent secure. Given enough time and determination,
if someone wants to target you and access your network, WEP encryption can
be bypassed using software such as AirSnort.

Filter the MAC addresses that are allowed to connect to your router. This
would require that you enter your router configuration and input the MAC
address of each wireless card you have. This will restrict access so that
only your computers can connect to the router. You will need to obtain the
MAC address (which is the individual identification address of a network
card in the form a 12 digit hexadecimal number). If someone sniffs traffic
and detects the MAC address of a computer wirelessly using your network,
the hacker could emulate that address and connect to the router, but
this takes time.

If you configure file sharing on your computers, make sure it is password
protected. You should not share files on your networked computers unless it
requires an authenticated user to access. Set up the same user accounts on
your machines so that your computers can share files.

With these relatively simple steps, wireless network users can secure their
networks from outside hackers. Wireless networks are inherently insecure, and
these tips will merely help you greater secure your network. If someone is
really determined to gain access to your network, given enough time, a good
hacker can get access. These tips will deter the average novice hacker from
gaining access to your network, however. Although these methods are not
definite security measures, they will change your network from being
something that can be hacked in a matter of seconds, to something that will
take a determined hacker days if not weeks of work, all of which will have
to be done while in close proximity to your network.
