Which information security principle aims to ensure that information is only accessible to those who are authorized?

The chosen answer focuses on the principle of confidentiality, which is essential in the realm of information security. Confidentiality ensures that sensitive information is only accessible to individuals who have the proper authorization. This principle serves as a critical component in protecting data from unauthorized access, thereby safeguarding personal and sensitive information from being exposed or misused.

Confidentiality measures might include various techniques such as access controls, encryption, and strong authentication mechanisms. By ensuring that only authorized users can access certain information, organizations can protect against data breaches and maintain the trust of their clients and stakeholders.

In contrast, while integrity refers to the accuracy and authenticity of the information, and availability ensures that authorized users have access to information when needed, these principles do not specifically focus on limiting access to only those who are authorized. Non-repudiation, on the other hand, guarantees that individuals cannot deny their actions regarding information or data, but this principle does not directly address access control.
