Case study using a digital video recorder (DVR)

Let’s assume that you have been given the task of performing a TARA for a video recording function in an ADAS system that continuously records video data to capture a 20-second window around the time an automatic emergency braking (AEB) event is triggered. The recording is then made available for an external client to download either through the USB interface or the telematics unit. This is needed to analyze the event details and determine responsibility in the case of a crash. Your task is to identify high-risk threat scenarios related to this feature and define the necessary risk treatment decisions. Let’s walk through the steps of applying the practical TARA approach to this use case.

Note

The following analysis is an abridged version of a full TARA and is not meant to be comprehensive.
