During the past decade, computers and networks, particularly the Internet and wireless technologies, have become an integral part of our lives. With the explosive growth of computer systems and Internet applications, there has been a steady rise in occurrence of security attacks which resulted in significant attentions on computer security and the imperative need for its education and training. A computer security course usually has been considered as an abstract academic discipline in most of science and engineering programs, and thus it is still not commonly offered in related engineering technology programs, i.e. computer engineering and electrical engineering technologies. Since security defense occurs at different levels, from personal level to corporate and national levels, it will be imperative to teach the EET/CET students the knowledge and skills of computer security and prepare them for the future jobs since most of them are working in the industry to develop, to maintain and operate the computers and networks. This paper describes such a course developed for EET/CET programs including the objectives, course content and lab exercises.
