Definition
The CIA Triad is a foundational Information Security model describing three essential properties of protected information: Confidentiality, Integrity and Availability.
Human Explanation
The CIA model helps define what must be protected and what consequences may follow from an Information Security breach.
Why it Matters
Most security requirements can be connected to one or more properties of the CIA Triad.
Conceptual Boundary
The CIA Triad does not describe every aspect of security, but it provides the foundation for most modern Information Security management systems.
Practical Perspective
Organisations may prioritise Confidentiality, Integrity and Availability differently depending on their activities.
