PHOENIX: Building a Next-gen IDS for cellular devices operating on 4G/LTE


Little red riding hood

LTE (control-plane) protocol is susceptible to various attacks either due to a design weakness or an implementation flaw. Below, we are listing some examples of these attacks and their implications. Little red riding hood

The infrastructure of wireless broadband communication comprises of several components. The core-network (service provider) is responsible for all server-side management, and the base-stations provide a link of communication between any cellular devices (UE) and the core network.

Now, the question is how to add the necessary controls to secure billion of subscribers/users operating on a cellular network (i.e., AT&T, Sprint, T-Mobile and Verizon, etc.).

The project PHOENIX envisions an in-device detection system based that uses syntax-guided synthesis problem to learn attack signatures (past-time LTL formulas) from the network traffic messages.

These attack signatures encode the [generic] behavior of an attack and provide a lightweight (in-device) monitoring mechanism to alarm users about any ongoing attack.
