G'day folks We've talked about the air interface and the sim cards of GSM in an earlier discussion. I'm just getting acquainted with GPRS and would like to know if there are documented cases of the GPRS backbone (GGSN, DNS, etc.) being attacked from a mobile node. For those not familiar with GPRS, the network looks like this: laptop--mobile phone--GSM network--SGSN--GGSN--Internet and several Intranets The GGSN is effectively a router and is the first IP device encountered by the laptop. It could have firewall and DHCP functions. It connects to a DNS, charging gateway, NMS, etc. Regards Viraf Viraf K.
