Even in the midst of a global pandemic, there are still things that haven't changed—and probably will not change anytime soon. One is the importance of IT security for sysadmins and the companies these folks work for.
When you ask a new sysadmin, "What is IT security? And what tasks come with it?" you may get the following answer: "It's about keeping your applications, containers, and systems current by installing the latest available updates all the time." While this answer isn't wrong, there is so much more to explore, learn, and do in IT security.
