LEFT: A Testbed for Assessing Resiliency of LTE Mobile Communication Systems
The proliferation of mobile devices poses unprecedented security risks to the nation's mobile communication infrastructure. Many of these devices are shipped to the market with only weak security protection and their vulnerabilities significantly increase the attack surface of mobile communication systems. This webinar highlights our recent efforts in building a low-cost testbed called LEFT (LTE-Oriented Emulation-Instrumented Fuzzing Testbed) for evaluating the resiliency of 4G/LTE mobile communication systems against malicious attacks or unexpected events. LEFT applies advanced AI techniques to perturb the actions of some modules in an LTE network, leveraging high-fidelity LTE network emulation to assess the impact of the deviant behavior. We will demonstrate the evaluation results of a few Android 4G/LTE mobile phones using LEFT.
