The invention and spread of the Internet is undoubtedly one of the greatest achievements of man. The Internet, a network that connects other smaller networks and individual computers globally, provides communication between people regardless of the geographical distance that separates them, allowing unimpeded access to a huge amount of information. The development of the Internet has changed the lives of modern people to a great extent in all its fields: society, education, economy, politics, art, entertainment, etc. The internet has changed our lives to a great extent and has certainly radically changed the way we deal with computers. The evolution of the internet has also changed, to the extent that computers infiltrate our daily lives in ways that are not always immediately visible, and change our entire lives. Nowadays, the internet incorporates incredible communication and interaction capabilities, while its usability is similar to that of a simple telephone or a simple home (or portable) device. The purpose of this work is, among other things, to identify some of the risks and to inform of the consequences and how to deal with them.
