Many sources equate secure communications to encryption. While encryption certainly plays a key role in a secure communications solution, it is not the only required element. The cybersecurity industry uses a model referred to as the security triad to define the various domains that need to be addressed when securing a network. The triad – sometimes also known as CIA – includes Confidentiality, Integrity, and Availability. This paper will review and define these domains for a better understanding of what is required to provide a complete secure communications solution.
