In a hybrid cloud environment, a 'Virtual Private Network (VPN)' is commonly used to ensure secure data transmission between on-premises data centers and the cloud. VPNs create encrypted communication tunnels over the public internet, enhancing security. Data encryption alone may not secure the entire transmission path.

The technology that enables one physical piece of hardware to function as multiple "logical" devices is called 'Virtualization.' It abstracts and isolates resources for efficient use.

Defense-in-Depth is a comprehensive security strategy that involves implementing multiple layers of defense mechanisms to protect an IT system, making it more resilient to various threats and attacks.

Hypervisor virtualization allows multiple operating systems (OS) to run on a single physical machine simultaneously. A hypervisor, also known as a virtual machine monitor, manages and allocates resources to each virtualized OS, enabling efficient utilization of hardware resources and facilitating tasks like testing different OS environments on a single server.

In computer architecture, the 'control unit' is responsible for managing instruction execution. It fetches, decodes, and coordinates the execution of instructions, ensuring the proper flow of data and control within the CPU.

Data Integrity Check ensures that data remains unaltered during transmission. This is typically achieved through methods like checksums or hash functions, which detect any changes in data.

'Platform as a Service (PaaS)' is a cloud computing service that provides a platform for developers to build, deploy, and manage applications without having to manage the underlying infrastructure. It abstracts hardware and allows a focus on software development.

Data Loss Prevention (DLP) systems are primarily designed to 'protect against hackers' and unauthorized access, ensuring sensitive data doesn't fall into the wrong hands. They use policies and rules to monitor and prevent data breaches.

In agile project management, a 'Sprint' is a fixed-length iteration typically lasting two to four weeks during which the development team creates a potentially shippable product increment. Sprints are a core component of the Scrum framework, an agile methodology.

In this case, the primary ERP module to consider is the 'Financial Accounting Module' as it is focused on managing financial aspects and integrating them with other business processes, including supply chain management.
