RE: Questions on GSM Penetration test

[<Lubomir.Nistor () star-21 de>]

I really doubt that there is any company like this.. as not many people on this planet know how exactly GSM network 
works, and those people are building it..

Penetration test of GSM net should be done as a normal pen-test, but I suppose insider attack is where can be done a 
lot.
outside attacks have to do something with radio engineering and basestation-phone communication (DoS, wiretaping, ..)

inside attacks are more interesting, as you can access devices via IP :) no radio :)
and do some serious (mis)configuration. 


Although I haven't done any GSM pentests, but i know some radio networks basics...

PS: if anybody got some docs about how GSM radio communication works pls send me a copy (not general descr, but 
specific protocol descr, fields descr, timing etc..)
PS2: sources of firmware helps as well..

Hello All,

        I would like to know if there is any company offering penetration test
services onto GSM network not the IP network. How to perform that type of
test? Which company can offer that service?

        Thanks.

Ricci
