Confidentiality, integrity, and availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization. Computer security is accomplished using many different systems, but the fundamental concepts are all rooted in the CIA triad. Confidentiality is preventing the disclosure of secure information to unauthorized individuals or systems. Integrity is maintaining and assuring the accuracy of data over its life-cycle. For information to be useful, it must be available when needed; thus, the need for availability. Everything in network operations and administration centers around CIA. The reason is that it is charged with all the network management functions that provide network fault indication, performance information, and data and diagnosis functions.
- Identify a security threat to a component on your network to CIA that interests you. Explain how it is commonly detected and defended by the department in charge of operations and administration.
