This paper reports on the experience of using the EDURange framework, a cloud-based resource for hosting on-demand interactive cybersecurity scenarios. Our framework is designed especially for the needs of teaching faculty. The scenarios we have implemented each are designed specifically to nurture the development of analysis skills in students as a complement to both theoretical security concepts and specific software tools.Our infrastructure has two features that make it unique compared to other cybersecurity educational frameworks. First, EDURange is scalable because it is hosted on a commercial, large-scale cloud environment. Second, EDURange supplies instructors with the ability to dynamically change the parameters and characteristics of exercises so they can be replayed and adapted to multiple classes. Our framework has been used successfully in classes and workshops for students and faculty. We present our experiences building the system, testing it, and using feedback from surveys to improve the system and boost user interest.
