The purpose of this study was to investigate preservice teacher knowledge regarding the about cyberethics, cybersafety, and cybersecurity (C3) topics. The study also aimed to identify what C3 topics preservice teachers report that they currently know well enough to model or teach. The researchers designed the C3 Awareness and Instructional Preparedness Instrument to examine the preservice teachers' ability to model or teach 75 C3 topics. The results reveal that the preservice teachers surveyed do not possess adequate C3 knowledge nor the ability to teach their future students to keep themselves and their data safe from harm.
