The three basic concepts in the history of Internet security are confidentiality, integrity and availability. If an unauthorized person to read or copy information that leads to a loss of confidentiality. If the information is modified so unbalanced, leading to loss of integrity. If the information is removed or is no longer accessible, this leads to loss of availability. Thus the history of Internet security is playing an important role.
Authenticationand authorization are the main methods of Internet security system, with corporate information available to those who are willing and able to become familiar with it. If the type of authentication can not be disproved, it is called non-repudiation.

Users of the ARPANET was a small group of people, and everyone knew and trustedother. They played jokes each other through the network - news and weird jokes and security breaches recently. Cliff Stoll at Lawrence Berkeley National Laboratory in northern California identified the first incident of international security in 1986.
An international venture, it was through the network systems in the United States and enter duplicate information in connection. This was the result of a simple accounting error in the computer records system ARPANET. Firstincident was reported automated the Morris worm in 1988.
