Intro

Studying is important to becoming a cybersecurity pro. So, try this exercise on your own once you get the gist of it.

IaaS

Definition:

Infrastructure as a Service (IaaS). A marketing term used to describe cloud-based systems that are delivered as a virtual solution for computing.

OSI Layer:

Layers 1–3 (Physical, Data, Network Layers)

At the Physical Layer, IaaS involves the physical hardware that provides the computing resources, such as servers, storage devices, and networking equipment. These resources are typically housed in data centers and provide the underlying infrastructure for IaaS services.

At the Data Link Layer, IaaS involves the network connections that provide connectivity between the physical hardware and the virtual resources that are created and managed by the IaaS provider. This may include the use of virtual LANs (VLANs) and virtual switches to segment traffic and provide isolation between different virtual environments.
