Question

In general how many key elements constitute the entire security structure?

(a) 1

(b) 2

(c) 3

(d) 4

Answer 1

Correct option is (d) 4

For explanation: The 4 key elements that constitute the security are: confidentiality, integrity, authenticity & availability. Authenticity is not considered as one of the key elements in some other security models, but the popular CIA Triad eliminates this as authenticity at times comes under confidentiality & availability.
