But it seems to have been well established as a foundational concept by 1998, when Donn Parker, in his book Fighting Computer Crime, proposed extending it to a six-element framework called the Parkerian Hexad. The CIA triad goal of confidentiality is more important than the other goals when the value of the information depends on limiting access to it. Bell-LaPadula. The data transmitted by a given endpoint might not cause any privacy issues on its own. Put simply, confidentiality is limiting data access, integrity is ensuring your data is accurate, and availability is making sure it is accessible to those who need it. The CIA Triad is an information security model, which is widely popular. Confidentiality; Integrity; Availability; Question 2: Trudy changes the meeting time in a message she intercepts from Alice before she forwards it on to Bob.
