Wi-Fi Security »
Last week at Defcon 20, Moxie Marlinspike released chapcrack,
a tool that implements a new attack against
MS-CHAPv2. It was widely reported as an attack on
WPA2-Enterprise, but it’s not. In fact, from a Wi-Fi perspective,
there’s nothing to see here.There’s been a great deal of coverage of the...
In the world of cool Wi-Fi features, Aerohive's
Private Pre-Shared Key is one that should get so much more
airtime (haha, pun intended) but instead often ends up as one more
awesome Aerohive feature mentioned in
passing.The fact that our engineering team was able to provide a
highly-secure,...
Last week, my
original post on the Wi-Fi Protected Setup (WPS) brute-force
attack promised a follow-up. In the meantime, I appeared as a guest
on episode 2 of the
No Strings Attached podcast with Dan Cybulskie and Andrew vonNagy.In some of the discussions I’ve had since then, it appears that...
One of the Wi-Fi industry’s greatest accomplishments is the way
that security went from being a major topic of interest ten years
ago to a quality that is accepted as an inherent part of Wi-Fi.
Wi-Fi Protected Access (WPA) had a great deal to do with that sea
of change in my opinion.The upshot of...
In July, Aerohive announced a new addition to our line-up of
enterprise 802.11n
wireless access points: the 3-spatial stream HiveAP 330 and
HiveAP
350. Although there is a lot to like about them, today I want
to dig down further into the radio card design that Devin first
touched on in his post...
When talking about security on Wi-Fi networks, I will sometimes
open with a statement like, “I have been around this industry so
long that I remember when WEP (Wired Equivalent Privacy) was
secure.” I also remember using products that didn’t implement the
“optional” WEP because it was too taxing for...
I’ve
written previously about the possibilities for gigabit Wi-Fi
coming with the future 802.11ac and 802.11adstandards. In today’s post, I’ll be taking a closer look about
what that raw speed means for security. (As far as the title
goes, well, let’s just say that in the mid-1980s, I was just...
Reading John Cox’s recent article in
NetworkWorld about Wi-Fi security
made me pause, and think about how much the Wi-Fi
Alliance has done to improve security on wireless LANs.
My work with Wi-Fi began about a decade ago, when I brought my
first AP home. It was a 2 Mbps AP, and it was powerful and...
I was recently elected chair of the Security Marketing task
group at the Wi-Fi Alliance, and one of the projects we are
working on could benefit from data on the deployment of different
types of security.
That is, what fraction of wireless networks are
open/WEP/WPA/WPA2?
In the past, the task group...
