Public clouds offer services to anyone, regardless of affiliation, and are the most likely to offer free services to users. Examples of public clouds with free services include iCloud, Dropbox, and OneDrive. Private cloud models are designed for specific customers and for their needs, and would not offer services to the public at large, for free or otherwise. A community cloud is specific to a group of similar organizations and would not offer free or widely available public services. A hybrid cloud model would not fit the specifics of the question.

To monitor data in transit, a DLP solution would optimally be installed at the network perimeter, to ensure that data leaving the network through various protocols conforms to security controls and policies. An application server or a web server would be more appropriate for monitoring data in use, and a database server would be an example of a location appropriate for monitoring data at rest.

Volume storage is allocated via a LUN to a system and then treated the same as any traditional storage. The operating system is responsible for formatting and securing volume storage as well as controlling all access to it. Applications, although they may use volume storage and have permissions to write to it, are not responsible for its formatting and security. Both a hypervisor and the management plane are outside of an individual system and are not responsible for managing the files and storage within that system.

Baselines are a set of configurations and policies applied to all new systems or services, and they serve as the basis for deploying any other services on top of them. Although standards often form the basis for baselines, the term is applicable in this case. Hardening is the process of securing a system, often through the application of baselines. Leveling is an extraneous but similar term to baselining.

The authentication mechanisms and implementations are the responsibility of the cloud provider because they are core components of the application platform and service. Within a SaaS implementation, the cloud customer will provision user access, deploy branding to the application interface (typically), and provide or procure training for its users.

Dealing with users or user access would not be an appropriate item for inclusion in an SLA specifically. However, user access and user experience would be covered indirectly through other metrics. Memory, CPU, and network resources are all typically included within an SLA for availability and response times when dealing with any incidents.

The Security Assertion Markup Language (SAML) is the most widely used method for encoding and sending attributes and other information from an identity provider to a relying party.WS-Federation, which is used by Active Directory Federation Services (ADFS), is the second most used method for sending information to a relying party, but it is not a better choice than SAML. XML is similar to SAML in the way it encodes and labels data, but it does not have all of the required extensions that SAML does. HTML is not used within federated systems at all.

During the data-in-use state, the information has already been accessed from storage and transmitted to the service, so reliance on a technology such as digital signatures is imperative to ensure security and complement the security methods used during previous states. Data in transit relies on technologies such as TLS to encrypt network transmission of packets for security. Data at rest primarily uses encryption for stored file objects. Archived data would be the same as data at rest.

The Safe Harbor regulations were developed by the Department of Commerce and are meant to serve as a way to bridge the gap between privacy regulations of the European Union and the United States. Due to the lack of adequate privacy laws and protection on the federal level in the US, European privacy regulations generally prohibit the exporting of PII from Europe to the United States. Participation in the Safe Harbor program is voluntary on the part of US organizations.

These organizations must conform to specific requirements and policies that mirror those from the EU, thus possibly fulfilling the EU requirements for data sharing and export. This way, American businesses can be allowed to serve customers in the EU. The Health Insurance Portability and Accountability Act (HIPAA) pertains to the protection of patient medical records and privacy. The Gramm-Leach-Bliley Act (GLBA) focuses on the use of PII within financial institutions. The Sarbanes-Oxley Act (SOX) regulates the financial and accounting practices used by organizations in order to protect shareholders from improper practices and errors.
