Ben Miller, a VP at cybersecurity firm Dragos, traces back early mentions of the three components of the triad in a blog post; he thinks the concept of confidentiality in computer science was formalized in a 1976 U.S. Air Force study, and the idea of integrity was laid out in a 1987 paper that recognized that commercial computing in particular had specific needs around accounting records that required a focus on data correctness. Over the years, service providers have developed sophisticated countermeasures for detecting and protecting against DoS attacks, but hackers also continue to gain in sophistication and such attacks remain an ongoing concern.
