GSM Security Feature, Threats and Solution

GSM which is Global System for Mobile communication,  is a digital mobile telephone system. It is widely used in Europe and other parts of the world. GSM supports voice calls with the data transfer speeds of up to 9.6 kbit/s and not forgetting transmission of Short Message Service (SMS).

Gsm threats

·         Eavesdropping

 This is the capability that the intruder eavesdrops signaling and data connections associated with other users. The required equipment is a modified MS.

·         Man – in – middle attack

This is the capability whereby the intruder puts itself in between the target user and a genuine network and has the ability to eavesdrop, modify, delete, re-order, replay, and spoof signalling and user data messages exchanged between the two parties. The required equipment is modified BTS in conjunction with a modified MS.

·         Impersonation of a user.

 This is the capability whereby the intruder sends signaling  and/or user data to the network, in an attempt to make the network believe they originate from the target user. The required equipment is again a modified MS.

Gsm Security Features

·         Anonymity

It will not be easy to identify the user of the system. In a way, it protects the user.

·         User Data and Signaling protection

The user pass data over the internet path is protected.

·         Authentication

The operator will know who is using the system for billing purposes.

GSM Solution

 It do not know if it is encrypted or not, the lack of user visibility. It is important to upgrade the cryptographic mechanisms. Protect against attacks.
