Hey everybody! Today we will talk about a fundamental concept — what is cybersecurity.
What is cybersecurity?
When coming to cybersecurity, people often think of Virus, IT, or Internet. Some people will say as long as we have a firewall, we are fine. Some people will talk about passwords like how long and how complex your password should be. Some people will mention data protection or encryption. And, of course, many people will talk about hackers, because they are on the news almost every day.
All of these are right, but we need a complete picture of cybersecurity. There’s an old story of “Blind men and an elephant”. A group of blind men have never known an elephant. They try to tell what the elephant is like by touching it. Then they claim the elephant is like a rope, a fan, a snake, a wall, or some other things based on which body part they put their hands on. It is just like when people are talking about cybersecurity.
People will say cybersecurity is about Virus, IT, Internet, Firewall, Data, Encryption, or hacker based on their own experience. So here I want to give you a big picture of cybersecurity, the complete picture of this elephant. Of course, it’s not an absolute answer. Different books, curriculums, or organizations may explain it differently, and the security industry also involves very fast with new technologies, concepts, and models added. Cybersecurity right now is often used as one word.
To fully understand it, we need to separate it into two words. Cyber and Security. First, what is cyber? We are living in a physical world. Just look around. You are in the room, sit by a table, have something to drink. But we are also living in a digital world at the same time.
