Tele-lab IT security: a means to build security laboratories on the Web

Providing hands-on experience by live exercises is essential for current IT security education. Therefore, Tele-Lab IT security, a Web-based training system, is being developed at the University of Trier, Germany. It attempts to integrate a security laboratory on the Internet using well-managed virtual machines which allow students to gain experiences of security technologies and tools in a reliable and secure way. We describe user interface and architecture as well as some security considerations.
