History Of Cyber Security

Cyber Security's history is very Interesting. The Origin of CS begain with a research project. It only came into existence because of the development of viruses.

1. In 1969, Leonard Kleinrock, professor of UCLA (university of California Los Angles) sent message to Standard Research Institute. This is well known story and a moment in the history of a digital world.
              The sent message was the word "Login".   The system crashed after they typed two letters "Lo". since than, this story has been a belief that the programmer typed the beginning  message "Lo and behold".
Those two letters of message were changed the way we communicate with one another.


2. In 1970's, Robert (Bob) Thomas created the first computer worm (virus). He realized that it was possible for a      computer program to move across a network,  He named the program Creeper, printing the message "I'M THE CREEPER: CATCH ME IF YOU CAN."
          An American computer programmer named Ray Tomlinson, the inventor of email, He saw this idea and liked it. He tinkered (an act of attempting to repair something) with the program and made it self-replicating "the first computer worm." He named the program  Reaper, the first antivirus software which would found copies of The Creeper and delete it.


3. In 1986, the Russians were the first who implement the cyber power as a weaponMarcus Hess, a German citizen, hacked into 400 military computers, including processors at the Pentagon. 


4. In 1988, an American computer scientist, Robert Morris, wanted to check the size of the internet. He wrote a program for testing the size of the internet. This program went through networks, invaded Unix terminals, and copied itself. The program became the first famous network virus and named as Moris worm or internet worm.
