Explanation
Data loss, leak prevention, and protection is a family of tools used to reduce the possibility of unauthorized disclosure of sensitive information. SIEMs are tools used to collate and manage log data. AES is an encryption standard.

Explanation
With multitenancy, multiple customers share the same physical hardware and systems. With the nature of a cloud environment and how it writes data across diverse systems that are shared by others, the process of eDiscovery becomes much more complicated. Administrators cannot pull physical drives or easily isolate which data to capture. They not only have to focus on which data they need to collect, while ensuring they find all of it, but they also have to make sure that other data is not accidently collected and exposed along with it.
Measured service is the aspect of a cloud where customers only pay for the services they are actually using, and for the duration of their use. Portability refers to the ease with which an application or service can be moved among different cloud providers. Broad network access refers to the nature of cloud services being accessed via the public Internet, either with or without secure tunneling technologies. None of these concepts would pertain to eDiscovery.

The Sarbanes-Oxley (SOX) Act is not an act that pertains to privacy or IT security directly, but rather regulates accounting and financial practices used by organizations. It was passed to protect stakeholders and shareholders from improper practices and errors, and it sets forth rules for compliance, regulated and enforced by the Securities and Exchange Commission (SEC). The main influence on IT systems and operations is the requirements it sets for data retention, specifically in regard to what types of records must be preserved and for how long.

Explanation
During the share phase, data is allowed to leave the application for consumption by other vendors, systems, or services. At this point, as the data is leaving the security controls of the application, the use of DLP technologies is appropriate to control how the data is used or to force expiration. During the use, create, and store phases, traditional security controls are available and are more appropriate because the data is still internal to the application.
