Over the past two decades, the world around us has significantly changed. There are new professions, new technologies and, of course, new problems with attempts to solve them. I was lucky to be involved in one of the most interesting and dynamic areas of modern times - Information Security. In my talk, I want to discuss how the world of information security has changed for me as a researcher in the process of my development, and how I see it now. And why is InfoSec worth your effort ;)
