Which term describes the characteristic of data not being disclosed to unauthorized entities?

1. Integrity

2. Confidentiality

3. Availability

4. Authentication

The correct answer is: Confidentiality

The term that describes the characteristic of data not being disclosed to unauthorized entities is confidentiality. Confidentiality is a fundamental principle of information security that focuses on ensuring that sensitive information is accessed only by authorized individuals. This involves various security measures, such as encryption, access controls, and policies that restrict who can view or utilize the data. In a cybersecurity context, maintaining confidentiality is crucial to protect sensitive data such as personal identifiable information (PII), financial information, trade secrets, and classified materials from being accessed by those without permission. Effective confidentiality measures help organizations prevent data breaches and establish trust with stakeholders, clients, and customers. Integrity, on the other hand, refers to the accuracy and consistency of data, ensuring that it has not been altered or tampered with. Availability pertains to the assurance that data and resources are accessible to authorized users when needed. Authentication involves verifying the identity of a user, device, or system, determining whether they are who they claim to be. Each of these terms relates to different aspects of cybersecurity, but confidentiality is distinctly associated with preventing unauthorized access to sensitive information.
