Study Notes
A Brief History of Computer Security
- Computer security emerged during World War II to protect mainframes used for communication code breaking.
- The primary threats were physical theft, espionage, and sabotage.
- The ARPANET was developed in the 1960s to enable mainframes to communicate more efficiently.
- ARPANET became popular in the 1970s and 80s, but its security was vulnerable due to insufficient controls and safeguards.
- The Rand Report R-609 defined the scope of computer security, expanding it beyond physical security to securing data and limiting unauthorized access.
- MULTICS was the first operating system to integrate security into its core functions, while UNIX did not prioritize security.
- The personal computer and networking in the 1970s gave rise to the Internet in the 1990s.
- Early Internet deployment treated security as a low priority, leading to problems with e-mail security today.
- Physical security of data centers was lost with the rise of networked computers, exposing stored information to security threats.
- Today, the security of each computer's stored information is contingent on the security of every other computer it is connected to.
- Cyber-attacks have made governments and companies more aware of the need to defend critical infrastructure.
- Computer security has evolved from physical security to protecting data and limiting unauthorized access, with a growing emphasis on defending against cyber-attacks.
