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...
