RISK-1 Context The fictional company BarkRun is releasing COLME, a new smart collar for dogs. COLME integrates WiFi, 4G/5G, GPS, Bluetooth and a microphone, enabling the following features: To initialise and setup COLME, the owner must download a specific app (available for Android and iOS) on a smartphone that needs to be paired with COLME via Bluetooth. During setup, the owner must record a model of their voice, provide the GPS location of the home, provide any account for fitness service (see below) and the details of any home WiFi network. All this information is stored directly on the collar. The owner of the dog is automatically authenticated using voice recognition (using the voice recorded during the initialisation). If someone else talks to the dog while outside of the home for more than 10 minutes without the owner speaking, an alarm is automatically raised using the 4G/5G network to a BarkRun server (see below). Any journey taken by the dog is automatically tracked by GPS and can be uploaded to general fitness services (such as Strava) once the dog is back home and automatically connected to the home WiFi network. . The owner of the dog can send short text messages to pre-stored numbers using voice recognition BarkRun stores in the Cloud a unique configuration file for each COLME customer, which includes a backup of their initial configuration. This file is encrypted using OpenSSL AES-256-CBC, using the MD5 hash of the name of the dog as encryption key. BarkRun also stores all the dog activities (similar to those uploaded to general fitness services) via WiFi. . Instructions. You need to provide a threat/attack tree for COLME. You are free to use any tool you wish to create the tree, but it should be submitted as as PDF or JPEG. The marking criteria is the same as the one used for the formative coursework and is provided below
