Design and Implementation of a PHP-based Web Server for the Tele-Lab IT Security

The Tele-Lab IT Security project aims at specifying and implementing a web-based, intelligent tutoring system that allows computer science students, system administrators, and end users to get familiar with the basics of IT security. It provides a powerful, real-life working environment in which users can develop and practice solutions for problems of their every-day work with only little support by the teaching staff. This technical report focuses on the web-browser part of the Tele-Lab. It discusses the design and the implementation of a web framework that is responsible for user administration and for presenting the teaching contents in a user-friendly manner.
