Towards a federated and hybrid cloud computing environment for sustainable and effective provisioning of cyber security virtual laboratories

Cloud Computing (CC) and virtualization concepts are two advanced technologies introduced to empower distance and blended learning. Besides, they play a crucial role in equipping learners with practical skills and fostering hands-on experience to defend against cyber-attacks. Many Higher Education Institutions (HEIs) in developed countries have already embraced the promise of CC to raise educational standards. However, the pace of its adoption in developing countries has stagnated. Moreover, existing solutions in the literature are not sustainable. They either rely on on-premise infrastructure or are bound by a single cloud service provider. Consequently, they are likely prone to failures and a sudden outage. To fill this gap, this paper is a first that comprehensively addresses the above issues and introduces a federated hybrid CC system based on an extension of Apache Virtual Computing Lab (VCL). The proposed system provides an independent open-source implementation, greater configuration flexibility, and methodological improvements as compared to existing studies in the literature. In addition, it promotes the sustainability of the CC services, extensible cloud architecture, and fault tolerance. VCL is primarily focused on provisioning Virtual Laboratories (VL) for remote cybersecurity and computer networks education, with potential expansion to other domains of engineering education. In addition, this paper introduces GPT-TerminalPro, a terminal-based tool driven by OpenAI’s Generative Pretrained Transformer (GPT-3.5) that provides intelligent assistance to users while performing lab tasks. To experimentally evaluate the VCL’s performance, the standard Linux tools as well as the Apache benchmark and httperf HTTP load generators are utilized. VCL has been tested with 30 users and 61 virtual user computing environments provisioning to validate the overall performance. The results are fascinating: the provisioning time including all VCL background tasks is always less than a minute and utilizes fewer computing resources while providing a better user experience. This paper will encourage the adoption of CC in low-income countries.

Using a nested virtualization tool for teaching VPN fundamentals

A common problem of undergraduate courses about security and computer networks is the difficulty of providing practical exercises to students. Although different approaches have been followed to solve this problem, it is still an open issue. In this work, we first discuss several possible open-source simulation/emulation/virtualization tools that could be used in the design of a lab session for teaching Virtual Private Networks (VPN) fundamentals based on OpenVPN. Next, we describe how a hands-on lab about VPNs can be carried out with the selected virtualization tool, called NETinVM. The proposed lab starts installing the OpenVPN packages in client and server machines, as in a real-case scenario. Although in this case both client and servers are Kernel-based Virtual Machines (KVM) connected to networks inside NETinVM. The nested virtualization included in NETinVM allows to deploy all the required types of VPNs within the virtual machine, allowing the students to reproduce the lab without the need of a network infrastructure, and following exactly the same process required in a real scenario. The evaluation results show that the level of learning achieved by the students through this lab session seems to be high, and they consider this lab useful for their professional development, showing that virtualization technology can help in computer network education.
