What ensures that data can be transmitted without being intercepted by unauthorized parties?

Confidentiality is the principle that ensures data is accessible only to those who are authorized to view it. By implementing measures such as encryption, access controls, and secure communication protocols, confidentiality protects data during transmission, making it difficult for unauthorized parties to intercept and understand the information. This is critical in preventing data breaches and maintaining the privacy and security of sensitive information communicated over networks.

While the other principles—integrity, availability, and non-repudiation—are also important aspects of information security, they focus on different concerns. Integrity refers to the accuracy and trustworthiness of data, ensuring it hasn’t been altered maliciously. Availability guarantees that data and resources are accessible when needed by authorized users. Non-repudiation ensures that parties cannot deny their involvement in a transaction, thus providing proof of the authenticity and origin of data. However, none of these principles specifically addresses the need for data to be protected from interception during transmission as confidentiality does.
