Information, Communication, Security
Perhaps, you have not noticed, but the world is a significantly different place than it was just 5 or 10 years ago; it is radically different than it was 25 years ago, insanely different than it was 50 years ago ... frankly, the pace of change and improvement in the world was arguably much slower before the internet or before availability of ubiquitous availability of telecommunication options [like TV or radio] for the masses. Availability of information greatly changes how people and particularly groups, crowds or masses of people learn from others around the world. Information and communication technologies inform transportation, logistics, production and allocation of assets ... most importantly, better information radically changes the set of opportunities that someone can aspire to and that has an insanely huge impact upon the allocation of TIME or how we structures our days and lead our lives. If you don't notice this, it is perhaps because you have worked pretty hard at isolating yourself from new ideas and shutting yourself off from communication ... that might work for you, but at least, four or five billion or so of your fellow human beings are less shut off from communication and new ideas than they ever have been. Because of this, everyone should probably have some awareness of social networking, communication options, the programmatic content of data and information security ... especially as we move larger and even larger and still even larger portions of our lives and attentionspan to the virtual realm.
It might be best to start with understanding information security ... just as it might be best to put some clothing on before one goes out in public or outdoors in the elements. Clothing does not cloak or protect one's body from every observer, but, as with information security, a base level understanding prevents some problems, not just embarrassing wardrobe malfunctions. If one wants to learn more about information security, an excellent source of content is Omar Santos ... consider his content on O'Reilly, as well as the professional content that he has developed and curated. This includes Ethical Hacking Bootcamp, the Art of Hacking repository on Github, the first day's study guide, first day's class notes, second day's study guide, second day's class notes, third day's study guide, and third day's class notes for the hands-on labs (Day1, Day2, Day3) in his Ethical Hacking Bootcamp on O'Reilly. I am biased, but if I were looking for professional staff, I would tend to have much greater confidence and trust in the kind of individuals [like Omar Santos] who are working especially diligently at helping others in progressing in their own professional careers with things like Certified Ethical Hacker, Offensive Security Certified Professional (OSCP) Certification, or CompTIA PenTest+ certifications;
