The rise of technology has allowed all behaviors identified as bullying to take place online, on social networks, via e-mail or other platforms. These are called cyberbulling, which manifests itself even more easily because it is much easier for a person to hide behind screens and adopt certain behaviors. The ability to be anonymous in the virtual environment encourages aggressors and allows behaviors that, in real life, would not be put into practice. Therefore, it is very important to know the basic strategies to prevent cyberbullying, awareness and education being the most important ones. In this regard, the schools have to create a climate in which cyberbullying is seen by everyone as unacceptable and as a violation of human rights.
