5.2.2: understand security issues associated with the cloud and other contemporary storage
| Keyword | Definition |
|---|---|
| Abstraction | hiding unnecessary detail (e.g. what type of device data is actually stored on within a cloud computing service) in order to focus on what's important (e.g. data can be saved without needing a local storage device) |
| Always connected | a feature of cloud storage which makes it easier for both users and hackers to access compared to local storage devices |
| Cloud | using networked servers to provide storage and software services |
| Contemporary storage | using cloud storage services like Dropbox or Google Docs to replace local storage with virtualised network storage |
| Credentials | username and passwords that provide access to a file or service |
| Encryption | a feature of cloud storage which makes it more secure because data can only be accessed with the right credentials |
| Virtualisation | a type of abstraction where the true nature of a physical device is hidden from the user to share resources or simplify management. E.g. one physical server might be split into multiple virtual servers: one for each customer or web site that uses it. |
