Cybersecurity education increasingly requires immersive, hands-on environments that reflect real-world complexity. This paper presents a modular Cyber Range infrastructure built around a Windows Active Directory (AD) domain, designed specifically for academic training. The system enables realistic enterprise simulation, incorporates gamified scoring mechanisms, and utilizes automated assessment logic to support scalable, objective evaluation of student performance. The environment is deployed using Infrastructure-as-Code (IaC) techniques and integrates attacker tools, Security Information and Event Management (SIEM) logging, and remote access via Virtual Private Network (VPN). Pilot deployments indicate enhanced learner motivation, operational awareness, and instructional efficiency. The paper discusses system design, evaluation workflows, and situates the platform within current research on Cyber Ranges, gamification, and Security Operations Center (SOC)-oriented training.
