The History of Information Security
The need for computer security — that is, the need to secure physical locations, hardware, and software from threats arose during World War II when the first mainframes, developed to aid computations for communication code breaking were put to use

The History of Information Security
嗗 Multiple levels of security were implemented to protect these mainframes and maintain the integrity of their data. 嗗 Access to sensitive military locations was controlled by means of badges, keys, and the facial recognition of authorized personnel by security guards. 嗗 The growing need to maintain national security eventually led to more complex and more technologically sophisticated computer security safeguards.

The History of Information Security
During these early years, information security was a straightforward process composed predominantly of physical security and simple document classification schemes. The primary threats to security were physical theft of equipment, espionage against the products of the systems, and sabotage.

The History of Information Security
One of the first documented security problems that fell outside these categories occurred in the early 1960s, when a systems administrator was working on an MOTD (message of the day) file, and another administrator was editing the password file. A software glitch mixed
