The course has been produced in a production circle of Virtual Polytechnic of Finland. A detailed description of course development and course content is given. The chosen didactical approach is outlined. The graphical design of the learning platform is presented and motivated. The IT technology and the IT infrastructure needed to implement and use the learning platform of the course are described and assessed.

The course has been produced by Arcada Polytechnic as a part of the production team Computer Networks, Telecommunication and Telecommunication Systems in the Finnish Virtual Polytechnic. The article begins with an introduction to the evolution of the information security requirements, the different areas and uses for cryptography and to the need of an active network security administration. The structure of the Finnish educational system is presented together with the strategy, goals and structure of the Finnish Virtual Polytechnic. The course development process is described in detail together with the software tools used to produce the course material. The contents in each chapter of the virtual course are also presented in this article. The seven course chapters are: Introduction, Network Security Administration, Antivirus Protection, Firewalls, Cryptography and Network Security, Network Security Software and Security of Wireless and Mobile Networks. All animations and exercises are described in their context. The didactical approach of the virtual course is a guided excursion to which students enroll. The task sets, consisting of exercises and study directives, that the course teacher assigns each week to the students are introduced and explained in detail. The concept of step-by-step skill assimilation, which lies behind the student guidance process, is outlined together with descriptions of the different user skill levels. The background to the graphical design of the learning platform is illustrated and motivated. Both the communicating dimension, the interface, and the esthetical dimension, the layout, of the course graphical design are explained and analyzed in depth. Teaching Network Security in a Virtual Learning Environment 190 specific both server (course provider) and client (student) side IT requirements are presented. Teaching and learning experiences, gathered from assessment forms and interviews, are presented. General experiences and experiences from doing and supervising exercises during a test course held in spring 2003 are presented both from student and teacher perspective. Changes made on the course contents after the test course are presented together with planned future development of the course. Production of a virtual course has proved to be a demanding task where experts, like graphical designers, have to be included in the production team. Important issues in producing a virtual course are the proper choice of computer software and IT technology and a sufficient and realistic budget. Chapter 2-Network Security Administration The "Network Security Administration" chapter presents important security related issues of the broad concept of network administration together with information about user support and education. The roles of Security Incident Response Teams and Standardization organizations are presented together with examples of important network security standards and security administration software. The chapter includes three exercises to help students understand the chapter contents. The chapter is divided into the following sections:

The need for network security is caused by the introduction of distributed systems, networks, and facilities for data communication. Improved network security is required because of the rapid development of communication networks. Network security is achieved by using softwareand hardware-based solutions and tools.

Covered topics are protection against viruses and other malicious programs, firewall software, cryptographic software standards like IPSec and TLS/SSL, cryptographic network applications like Virtual Private Networks, secure Web, secure email, Secure Electronic Transaction, Secure Shell, secure network management, secure DNS and smartcard applications, as well as security administration software like intrusion detectors, port scanners, password crackers and management of network security software management. Tools and API's for security software development are presented. A four-level network security software skill taxonomy is proposed and implications of this taxonomy on network security education is outlined. University and polytechnic level network security education is surveyed and the need for inclusion of network security software development skills in such education is pointed out.
