As more of the activities of daily living take place online, computer security education for high school students is of increasing importance. To address this need, we design a course model as prototype curriculum to teach high school students about the basics of information security. Prototype examples of hands-on lab activities are also introduced for enhancing students' practical skills on information security. IT educators can consider the proposed work in this paper as a guideline for designing and developing information security courses to high school students. We identify challenges encountered in this process, and contend that these challenges stem from the nature of the information security field.
