Section: Network Security

Cloud computing has privacy concerns, regulation compliance difficulties, use of open-/closed-source solutions, and adoption of open standards. It is also unsure whether cloud-based data is actually secured (or even securable).

Incorrect Answers:
A: Because the files are not locally stored, size should not be an issue.
B: Availability of the files is not a security concern as the files will be available wherever Anne is able to access the internet.
C: Accessibility of the files from Ann’s mobile device is not a security concern if her mobile device has internet access.
