Anything as a Service (XaaS)

The concept that most types of IT requirements can be deployed as a cloud service model.

Software as a Service (SaaS)

A cloud service model that provisions fully developed application services to users.

Platform as a Service (PaaS)

A cloud service model that provisions application and database services as a platform for app development.

Infrastructure as a Service (IaaS)

A cloud service model that provisions virtual machines and network infrastructure.

Responsibility Matrix

Identifies shared responsibility for security implementation as applications, data, and workloads transition into a cloud platform.

Centralized Computing Architecture

A model where all data processing and storage is performed in a single location.

Decentralized Computing Architecture

A model in which data processing and storage are distributed across multiple locations or devices.

A computing environment where multiple independent operating systems can be installed on a single hardware platform and run simultaneously.

High Availability (HA)

A metric defining how closely systems approach the goal of providing data availability 100% of the time while maintaining high performance.

Automatically copying data between two processing systems either simultaneously (synchronous) or from a primary to a secondary location (asynchronous).

Application Virtualization

A software delivery model where the code runs on a server and is streamed to a client.

An OS virtualization deployment containing everything required to run a service, application, or microservice.

Features and capabilities of a server without needing to perform server administration tasks, offloading infrastructure management to the cloud service provider.

Virtual Private Cloud (VPC)

A private network segment made available to a single cloud consumer on a public cloud.

An independent, single-function module with well-defined and lightweight interfaces and operations, allowing for rapid, frequent, and reliable delivery of complex applications.

Infrastructure as Code (IaC)

Provisioning architecture where deployment of resources is performed by scripted automation and orchestration.

Software-Defined Networking (SDN)

APIs and compatible hardware/virtual appliances allowing for programmable network appliances and systems.

Network Functions Virtualization (NFV)

Provisioning virtual network appliances, such as switches, routers, and firewalls, via VMs and containers.

Software-Defined Wide Area Network (SD-WAN)

Services using software-defined mechanisms and routing policies to implement virtual tunnels and overlay networks over multiple types of transport network.

Secure Access Service Edge (SASE)

A networking and security architecture providing secure access to cloud applications and services while reducing complexity.

An electronic system designed to perform a specific, dedicated function, such as a microcontroller in a medical drip.

Real-Time Operating Systems (RTOS)

A type of OS that prioritizes deterministic execution of operations to ensure consistent response for time-critical tasks.

Industrial Control Systems (ICSs)

Network managing embedded devices designed to perform a specific, dedicated function.

Human-Machine Interfaces (HMIs)

Input and output controls on a PLC to allow a user to configure and monitor the system.

Software that aggregates and catalogs data from multiple sources within an industrial control system.

Supervisory Control and Data Acquisition (SCADA)

A type of industrial control system managing large-scale, multiple-site devices and equipment spread over large areas from a host computer.

Internet of Things (IoT)

Devices that can report state and configuration data and be remotely managed over IP networks.

The security design paradigm where any request must be authenticated before being allowed.

In zero trust architecture, functions that define policy and determine access decisions.

Assignment/Accounting

Processes ensuring each physical and data asset have an identified owner, and are appropriately tagged and classified within an inventory.

Monitoring/Asset Tracking

Enumeration and inventory processes ensuring physical and data assets comply with configuration and performance baselines.

Acquisition/Procurement

Policies ensuring asset and service purchases and contracts are fully managed, secure, and meet business goals.

Standard Naming Convention

Applying consistent names and labels to assets and digital resources/identities within a configuration management system.

Configuration Management

A process through which an organization's information systems components are kept in a controlled state meeting security and compliance requirements.

The process by which the need for change is recorded and approved.

The process through which changes to the configuration of information systems are implemented as part of the organization's overall configuration management efforts.

A security copy of production data made to removable media, typically according to a regular schedule.

Backup that writes job data to media stored in the same physical location as the production system.

Backup that writes job data to media stored in a separate physical location from the production system.

The operation to recover system functionality and/or data integrity using backup media.

Used to create the entire architectural instance/copy of an application, disk, or system for backup processes.

A method used by file systems to record changes not yet made to the file system in a journal.

Disposal/Decommissioning

Policies governing the removal of devices and software from production networks and their subsequent disposal.
