Re: MAC Spoofing Prevention in Wireless



Charles,

Thanks for your reply. I'm aware and have been observing that Aruba is
pretty solid. I just wanted to understand the way it worked against
these attacks.

Aruba is safe.
You need to hack into a GRE tunnel from you to the AP
then you need to authenticate 802.1x just to get an ip addr

unless you have access to the controler you can say Aruba wifi is safe.

Hello List,

I have recently been involved in a security test of a wireless
environment using Aruba controllers and a captive portal. As an
obvious attack vector I tried spoofing the MAC (and IP) addresses of
valid authenticated users but it didn't grant me access. I've been
told that MAC spoofing prevention is one of the feature of the Aruba
wireless controllers.

I've Googled a bit but haven't come across a good explanation. How
does MAC spoofing detection work on wireless networks? What
information does a controller utilize on lower layers to detect that a
packet is coming from a spoofed MAC?

Can you please share the resource address
thanx

Thanks.
