Re: [WISPA] WiMAX Security
Dee,
There is a lot of interesting info and a lot of speculative and very
wrong info in that article on WiMAX security; especially the part saying
that it's easy to jam WiMAX. Witness the following text from the article:
"It is reasonably simple, however, for an attacker to use readily
available tools to jam the spectrum for all planned WiMax deployments.
In addition to physical layer denial of service attacks, an attacker can
use legacy management frames to forcibly disconnect legitimate stations.
This is similar to the deauthenticate flood attacks used against 802.11
networks.
Despite good intentions for WiMax security, there are several potential
attacks open to adversaries, including: Rogue base stations, DoS
attacks, Man-in-the-middle attacks and Network manipulation with spoofed
management frames... "
The article author imagines that jammers are going to have $30,000
licensed "rogue" base stations laying around to jam with.
The author somehow also imagines the possibility of jamming "all planned
WiMax deployments" - this is a ridiculous statement.
The author further imagines that jamming will be allowed by the FCC. The
FCC may not act against jammers in license-free spectrum but rest
assured that they will very likely act against jammers in licensed
spectrum. For example, if someone started jamming Verizon cellphone
towers, both Verizon and the FCC would act pretty quickly to find the
guilty party and have them arrested. They could probably even be charged
as a terrorist under current laws.
I'm glad you posted this link. Like many wireless articles these days,
this one contains some good information and some bad information. All we
need is the knowledge or the resources to tell which is which is which
is which...
