Implementation of Experimental Test Bed to Evaluate Security in Cellular Networks

The wide development of interconnectivity of cellular networks with the internet network has made them to be vulnerable. This exposure of the cellular networks to internet has increased threats to customer end equipment as well as the carrier infrastructure. If is very difficult to deal with the full fledged infrastructure in a typical service provider network due to operational constraints.However still it’s very important for an analysis to evaluate the vulnerabilities and take connective action. This paper introduces the modeling of a small cellular network with security weakness (2G, 2.5G, 3G).This is done by using of the shelf hardware components to set up an experimental test bed. The vulnerability of such cellular networks is attempted with the construction of a ghost GSM tower through shelf hardware components. This paper also discusses concepts of test bed GSM security and possibility of conducting man-in-the-middle attack on the cellular networks model.
