Consider a cloud based storage-as-a-service provider. It provides a storage service similar to Dropbox, where user files on their personal storage (e.g. laptop hard drives) are synchronized and saved in the cloud. 1. What is the attack surface of this storage service (i.e. where are the places the system (or user data) can be attacked?). 2. What are the assets in this system that should be protected? 3. Who can be the attacker and what capability can they have? (i.e. are they external or internal? What can an external attacker do? What can an internal attacker do? What is their motivation:?)
