In today's technology age, we have begun to reflect and live a large part of our lives in electronic media, which requires us to have knowledge in many aspects. In fact, only information is not enough. We must improve ourselves at all times and keep up with current information and developments. This is where the necessity of having information about cyber security emerges. We covered all this in this course. Not just us individuals! States, public institutions, social platforms, SMEs, all large and small private companies have also started to communicate with the services and products they offer to consumers or other companies and institutions through virtual environments. Isn't that the reason why we need to use technology more securely? This world, which we describe with concepts such as virtual world and cyber world, now takes place with the data we have produced with our virtual and real assets and our lives. We conduct most of our communication with other people in electronic media. So this course will tell you exactly these, with details, in an understandable language and visuals.
