Before we can properly discuss how to secure Hyper-V, we must reach an agreement on the words that we use. Terminology is a common point of confusion when it comes to Hyper-V and related technologies. This section will provide a definitive explanation for these terms, not only as they are used within this book, but also how they are generally used in official documentation and by experts.
The commonly used term Hyper-V Core and variants have no official meaning. Core is a special mode for Windows Server that does not include a GUI. It is often used to refer to Hyper-V Server, as that product also has no GUI. Crossing Hyper-V Server with the core modifier should be avoided as it leads to confusion.
