Abstract: This paper examines the critical roles of confidentiality, integrity, and availability, collectively known as the CIA triad, in modern cyber defence. The CIA triad has long been a foundational model in information security, and this review evaluates how each component contributes to protecting systems against evolving cyber threats. We discuss the meaning and significance of confidentiality, integrity, and availability in the context of cybersecurity and analize how they guide the design of defence strategies. Each element is explored in depth, highlighting common threats (such as data breaches, tampering attacks, and denial-of-service incidents) and corresponding safeguards and best practices. The interdependence among confidentiality, integrity, and availability is also evaluated, noting that an effective security posture requires a balanced approach that does not excessively favour one aspect at the expense of the others. We further consider the trade-offs organizations face in prioritizing these principles under different scenarios and requirements. Finally, emerging challenges are discussed: from the proliferation of Internet-of-Things (IoT) devices to the advent of quantum computing, new developments are testing the traditional CIA framework. The paper concludes that, despite new complexities and calls to expand security models, the CIA triad remains an essential guiding framework in cyber defense, albeit one that must be continually adapted to address modern threats.
