The networking blocks
The networking block allows the system to communicate. This communication can be done with other systems (mesh networking), with sensors, or with the system's backend. There is a wide variety of physical transport means (wired or not) for protocols over these layers. The typical interesting scenarios on a network level all pertain to breaching the trust between the system and its communication peers.
From a system point of view, we will typically listen to the traffic as a first step to evaluate the security of the communication with its peer to verify how hard it is to impersonate a peer, for example:
- We will look into impersonating a remote sensor to fool the system into harvesting fake data or to evaluate the system's capability to handle malformed information.
- We will look into impersonating the backend to distribute malicious firmware updates to evaluate the possibility of leveraging the system for nefarious activities.
