Timeline of the History of Information Security

To begin, review this timeline on the history and development of information security. What was the role of the US Department of Defense (DoD) in the evolution of information security? Who or what were the influencers in the development of the confidentiality, availability, and integrity (CIA) triad?


Information can be private or public, personal or generic, valuable or commonplace, online or offline. Like any other asset, it has to be protected. This is more important online where hackers can steal or misuse information remotely even without any physical access to where that information resides.

In line with evolving technology, data security practices have evolved from high-level principles into more detailed set of practices and checklists. In practice, there's no single list of principles that everyone agrees on. Many lists exist, each one customized for its context.
