Wireless Security


Do you know exactly how secure your wireless network is?

If you don’t, you’re certainly not alone. To see if your wireless network (or WAN) is secure, simply pull down on the pizza slice-shaped icon in the upper right corner of the screen. If there’s a lock icon to the right of the wireless network name, congratulations, you have a secure wireless network! (Note – you must be running Mac OS X.5 – Leopard – in order to check your network security this way.)

But if there is no lock, it means your wireless network is wide open, and anybody who is within range can piggyback on your network. And that can mean all sorts of trouble for you.

You should never allow unauthorized users to be able to access your wireless network, for many reasons, including:

• Security of your data: Anybody who is savvy enough to glom on to your network probably can figure out how to get to your data. It’s easy enough to imagine the bad things that could happen if your personal and professional data was compromised.

• Speed of your network: Even if the kid next door is doing no more harm than simply using your network to stream movies or download entire Dave Matthews Band concerts, all that traffic will slow your online speed down to a crawl. That means your download speed will be diminished, something you certainly don’t want.

• Legal reasons: If somebody is using your wireless network to download copyrighted or illegal material, or uses your IP address to post defamatory and/or threatening posts online, whose door do you think the authorities will knock on first?

Adding security to your wireless router is simple – how you do it depends on what brand you have. To configure using an Apple wireless product (AirPort Extreme, Express or Time Capsule), you will need to use AirPort Utility (included on every Mac, found in the UTILITIES folder (which is inside the APPLICATIONS folder).

Virtually every other brand of router is configured using a standard Web browser – Safari, Firefox or Google Chrome. You must enter the IP address of the router (which can be found in SYSTEM PREFERENCES>NETWORK) in the URL bar of your browser. Every model is different, but if you look for “Settings” or “Wireless,” you’ll be on the right track.
