GPRS Features, Threats & Solutions

GPRS is a kind of technologies to improve 2G phones (second generation phones) to allow transferring of data at higher speeds, GPRS allows mobile phones to remain connected to network and transfer requested or sent data instantly.

GPRS Features:

·         Multimedia applications

·         High speed connection

·         Always immediate connection

·         Internet connectivity from mobile phone

GPRS Threats:

·         Denial Of Service (DOS) attack

·         Integrity and Confidentiality

o   Capturing a subscriber’s data session

·         Authentication and Authorization

o   Spoofed create PDP request

o   Spoofed update PDP request

·         Availability

o   Border gateway bandwidth saturation

o   DNS flood

o   GTP flood

o   MS flood

o   DNS cache poisoning

o   Bad BGR routing information

o   Spoofed GTP PDP context delete 

GPRS Solutions:
