No WLAN On Your Nets? Wi-Fi Security’s Still a Concern

Main     Elsewhere     The Week in CrossNodes    

Color us jaded, but we thought tales of prowling wardrivers, like
this one from the AP
, were a fading memory. Evidently not. On the
bright side for enterprise-based wireless networkers, the reporter
seemed to think that the bulk of the unsecured networks he and his
wardriver companion were spotting were largely residential, in keeping
with the explosive growth of Wi-Fi among personal and SoHo computer
users. So maybe, the cold-hearted realist wants to believe, all these
unsecured wireless ‘nets will cause the average wardriver to pass the
juicier but more secure corporate nets by in the quest for free
bandwidth and a stepping-off point for disagreeable behavior.

But as much as we’d like to shrug off stories like this as old news
(and they are to networking professionals who’ve been making sure
there’s wireless pipe in range of the executive meeting rooms for a
few years now), it’s very simple to hang plug-n-play wireless devices
off “the last foot,” creating a situation where a well-meaning user
who isn’t responsible for your network’s security is
maintaining a surreptitious but dangerous and unsecured segment.

So even if you don’t even maintain a wireless network, wireless
networking technology and its relative security should be a concern.
If you maintain unencrypted services over your wired LAN, thinking the
physical security of your network is the final word in terms of its
virtual security could be a bad mistake.

» Trend Micro and Sofos
both issued their monthly “it’s as bad as you think and they are out
to get you” reports to kick off June. Both firms vary in the total
number of new worms, trojans, viruses, and assorted other malware
floating around out there, but they agree that Sasser was a pain in
May. In the “Grimly Amusing” department is a quote from an analyst in
who says that while there might be less unique examples of
malware out there, that’s largely a result of code reuse on the part
of malware authors.
