Wireless Security
FROM: NOV-DEC 2003 ISSUE | BY ROBIN DAY
There has been a lot of debate in the press lately about the security of wireless networks or the lack thereof. Critics point out the many possible problems with going wireless, while wireless proponents flaunt their lists of patches and plugs. The fact is wireless LANs can be almost as secure as their land-based cousins. The only reason I say 'almost' is that there is no way to prevent physical access to a wireless network (i.e. plugging in a cable). Aside from that, there are plenty of options available to ensure your private wireless LAN stays secure.

This introductory article runs through many of the considerations involved in setting up a wireless LAN. It begins by identifying many of the features to look for in your equipment, and then discusses how those features can be used to make security more effective. The article targets home users, but the advice certainly works for the Small Office/Home Office (SOHO) market as well.

This Intranet Journal is the Unofficial 802.11 Security Page. It is probably the most comprehensive resource I have run across. Far from being flashy, this mostly text site contains links to dozens of articles and PDF files on wireless security. If you want volume, you're in the right place.

Of course not everyone concerned with wireless is worried about security. You may be carting around a wireless-enabled notebook, just looking for a place to set up camp for a few hours of wireless Web surfing. If this is the case, check out the Wireless hot-spot locations site before you head out. It lists global wireless access locations, tells you if they are free or pay-for-play, and provides contact details.
On the other hand, you may prefer to stick to old fashioned cable-based networking. It may not be as flashy, but it does give you a built-in excuse for not working everywhere on the planet.
