Chapter 6: Cloud and Wireless Security

Multiprotocol Label Switching (MPLS)

A Layer 2.5 networking protocol.

Hybrid Cloud

A combination of public cloud storage and private cloud storage where some critical data resides in the enterprise's private cloud while other data is stored and accessible from a public cloud storage provider.

Desktop as a Service (DaaS)

A form of virtual desktop infrastructure (VDI) in which the VDI is outsourced and handled by a third party. Also called hosted desktop services, desktop as a service is frequently delivered as a cloud service along with the apps needed for use on the virtual desktop.

Cloud Computing

A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. NIST 800-145

Cellular Network

A radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station.

Cloud Provider, Cloud Services Provider (CSP)

A service provider who offers customers storage or software solutions available via a public network, usually the internet.

Voice over Internet Protocol (VoIP)

A set of technologies that enables voice to be sent over a packet network.

Service-Level Agreement

An SLA is a contract that exists between customers and their service provider or between service providers. It records the common understanding about services, priorities, responsibilities, guarantees, warranties, etc. to be provided — collectively, the level of service. The SLA may specify the levels of availability, serviceability, performance, operation or other attributes of the service, such as billing. In some contracts, penalties may be agreed upon in the case of non-compliance.

Anything as a Service (XaaS)

An imprecise, generic term which refers to the growth in services, tools, technologies and capabilities being offered via the internet to businesses and consumers. XaaS capabilities may or may not be cloud-hosted. Unlike SaaS, PaaS and IaaS, XaaS does not represent or imply any consistent architectural ideas, approaches, concepts or designs.

Identity as a Service (IDaaS)

Cloud-based services that broker identity and access management (IAM) functions to target systems on customers' premises and/or in the cloud.

Big Data

Large volumes of structured and unstructured data. It is differentiated from legacy structured data by five general characteristics: Volume of data collected, Velocity of data streams, Variety that data arrives in, Variability of where data is located, Value of the data to the organization. The data may be collected from multiple entities, internal systems and public sourced information. Properly protected, organized and analyzed, big data can provide healthcare organizations and patients with new insights in the delivery of healthcare services.

Private Cloud

The cloud infrastructure provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed and operated by the organization, a third party or some combination of them, and it may exist on or off premises. Source: NIST SP 800-145

Data Subject

The natural person who is identified or described by the data.

Cloud Migration

The process of transitioning all or part of a company's data, applications, and services from on-site premises behind the firewall to the cloud, where the information can be provided over the internet on an on-demand basis.

Cloud Storage

The storage of data online in the cloud, wherein a company's data is stored in and accessible from multiple distributed and connected resources that comprise a cloud.
