Information Security Education Journal Jianhua YANG, Thomas Reddington 2 1 2015 http://www.dline.info/isej/fulltext/v2n1/3.pdf Online teaching and learning have been becoming more and more popular because students can study at anywhere and anytime. The reality is that it is hard to ask online students to conduct hands-on labs which normally require students to be on-campus. Computer network security is a course in which hands-on labs play a key role in enhancing students learning performance. In this paper we first, discuss the challenges to design online hands-on lab; second, describe the contents covered in computer network security course; third, design a lab platform which can make online students convenient to do hands-on exercise; and finally, propose eight hands-on labs which are properly designed for computer network security online students. Our survey results show that the students are satisfied by the eight hands-on labs.
