What is the CIA Triad?
The CIA Triad is a foundational model in cybersecurity that represents three core principles: Confidentiality, Integrity, and Availability. These principles guide the design and implementation of Security Controls and frameworks across organizations.
Confidentiality ensures that data is accessible only to authorized users, Integrity ensures data accuracy and trustworthiness, and Availability ensures that systems and data are accessible when needed. The CIA Triad underpins frameworks such as NIST SP 800-53 and ISO/IEC 27001.
What is the CIA Triad used for?
The CIA Triad is used as a guiding framework for designing security architectures and evaluating risk. It helps organizations align Security Controls with business priorities and protect Critical Business Assets (CBA) and Critical Business Processes (CBP).
Security leaders use the CIA Triad to balance competing priorities and ensure that controls such as Access Control, Cryptography, and Backup strategies are implemented effectively within a Defense in Depth approach.
