Cyber Security..What is it?
Most crimes in real life have their online equivalent. These activities are called Cybercrimes. Threats on the internet are automated; you don't have to be a mega-corporation or a celebrity to be affected. They can harm anyone, and they do: everyone is affected, from your closest friend to your dearest enemy, even your dog. Cybersecurity is what we do to counteract those cybercrimes. When leaving the house, you (hopefully) lock the front door.
You might also close the window, turn on the alarm, and if you're going on holiday, you might take care not to shout it to the world. Cybersecurity works under the same principles. It fights cyber threats and enemies of all sorts; in whatever digitalized form they may come. A job in cyber security doesn't mean being a door against all of the cybercrimes of the world. It means making the door. It means puzzling out where that door needs to be, and where the threats trying to make their way through will go when their original plan fails. It means doing all of this while keeping that door a door, one capable of letting the right people through.
