Cyber Security is action to protect network and technolocy such as hardware, software, and data from cyberthreat. It is equally opposite to Hacking that is a criminal activity one that hack and crack a system, make a virus and steal the data instead of secure it.

A guy named Bob Thomas wrote a program that able to move across the network by itself and leave a small trail. He named it creeper, It is not actively malicious program because it doesn’t damage the data. It just prints the messages “I’m the creeper. Catch me if you can.”

Later, Ray Tomlinson saw it and he liked it. He modifed the program and make it self-replicated. Then it was accepted as computer worm.

Another worm named Morris Worm appeared in 1986 and caused mayhem on the internet. It attacked more than thousands of systems on the internet. It is around 10% computer that connected to internet.

But the program creator didn’t foresee ths consequences. More importantly this act also let to the formation of the computer emergency response team as a non-profit research center for systemic issues that micht affect internet as a whole.

Nowadays viruses were deadlier more invasive and harder to controle. We have already experianced cyber incidens on a massive scale and 2021 isn’t close to over but these atacks are anough to prove that cyber security is a necessity for corporations and small businesses alike
