examples below, your implementation and administration of network security measures is the key to maximizing wireless security.

No preventative measure will guarantee network security but it will make it more difficult for someone to hack into your network. Often, hackers are looking for an easy target. Making your network less attractive to hackers, by making it harder for them to get in, will make them look elsewhere.

How do you do this? Before discussing WEP, let’s look at a few security measures often overlooked.

1)Network Content

Now that you know the risks assumed when networking wirelessly, you should view wireless networks as you would the Internet. Don’t host any systems or provide access to data on a wireless network that you wouldn't put on the Internet.

2)Network Layout

When you first lay out your network, keep in mind where your wireless PCs are going to be located and try to position your access point(s) towards the center of that network radius. Remember that access points transmit indiscriminately in a radius; placing an access point at the edge of the physical network area reduces network performance and leaves an opening for any hacker smart enough to discover where the access point is transmitting.

This is an invitation for a man-in-the-middle attack, as described in the previous section. To perform this type of attack, the hacker has to be physically close to your network. So, monitoring both your network and your property is important. Furthermore, if you are suspicious of unauthorized network traffic, most wireless products come with a log function, with which you can view activity on your network and verify if any unauthorized users have had access.

3)Network Devices

With every wireless networking device you use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. If they get into the hands of a hacker, so do all of your settings. So keep an eye on them.

4)Administrator passwords

Your network administrator is the only person who can change network settings. If a hacker gets a hold of the administrator's password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator's password regularly.
