[PEN-TEST] SMS (Short Message Service) Security

[Ronen Segal <RONENSG () CELLCOM CO IL>]

Hello all.
I’m about to conduct a Security Risk Assessment about a- TDMA and GSM SMS
Services.
If you could please point me to an article that deals with this matter or
some thing that could help me get started by understanding the Risks SMS
poses to the Service provider and the Cellular Subscriber I would be very
Thankful.
Thank You.
