Survey of Open Source Technologies for Building Cyber Ranges for Exercises and Trainings

Cyber ranges (CRs) are critical platforms for training and research in the field of cybersecurity. They provide simulated environments that replicate real-world network conditions and attack scenarios. This paper provides an overview of current open source technologies suitable for implementing CRs for exercises and trainings, including open source CRs, virtualization platforms, and orchestration tools. The study evaluates open source CRs based on capabilities, training methods, and provided simulation features. In addition, the paper discusses criteria for selecting technologies and their interoperability. The findings serve as a quick reference guide for organizations aiming to build customizable and cost-effective CRs utilizing open source solutions.
