The explosive growth of computer networking enormously increases security costs. It is necessary to encourage the cooperation of students, faculty, and staff through education and training of information ethics, together with improving management and technologies, for security and to reduce university costs. We produced two collections of video clips for information ethics education for university students to be used as teaching materials. A new collection produced this year includes video clips about security including "information security policy" and "PKI (public key infrastructure)" which can also be utilized in security training courses for faculty and staff. In this paper, we discuss the effects of using the video clips in information ethics education in Japanese universities. We also discuss the use of the video clips in security training courses.
