Don’t think that you are safe from intruders accessing your wireless network just because you are in the safety of your own home. Someone may want to get to your information for some reason, you never know. Do you want your neighbours having access to your internet connection, downloading files, and racking up bills. That’s how easy it is if you have no wireless network security.
You can implement various types of security with a wireless network through settings on your router. If you have any passwords, be sure to write them all down.
Here are some different types of security you can use with a wireless network.
WEP (Wireless Encryption Protocol) works by establishing a shared key between the clients (network cards) and the wireless router, then using the key to encrypt and de-encrypt the data passing between them. Most routers offer both 64-bit encryption and 128-bit encryption. It is usually a 10 number key for 64-bit, and a 22 number key for 128-bit. If you do not know this number, you cannot enter the wireless network.
WPA – PSK (Wi-Fi Protected Access Pre Shared Key) is a Wi-Fi standard that improves upon the security features of WEP. To use WPA-PSK, a shared key or “passphrase” is set. Using TKIP (Temporal Key Integrity Protocol), WPA-PSK automatically changes the keys at a preset time interval, making it much more difficult for hackers to find and exploit them. MAC address filtering: Each network adapter or card (wired or wireless) has a unique number assigned to it called a MAC address. So if you have a wireless USB adapter plugged into your computer, when connected to the internet, it will show its own mac address. Here’s how to find your mac address in Windows XP You can add all the mac addresses of the computers you want to access the network, therefore blocking any others.
For instructions on how to setup these different network security types, consult your router manual, or online instructions for your particular brand.
