In recent decades, cyberethics, cybersecurity, and cybersafety have been the center of interest at schools. This chapter uses a case study approach to describe the issue of cyberethics, cybersafety, and cybersecurity (3Cs) as well as how problems of these three Cs are intermingled to become general cyberethics issues for the society. The chapter also promotes good cybercitizens at schools because it is of great importance for the school districts to take some measures to improve students' knowledge and awareness of cyberethics, cybersafety, and cybersecurity, to enhance the safety and security of school infrastructure, to avoid cyberbullying, to ensure students are good cybercitizens, and to help train teachers to be cyber professionals.
