Which cybersecurity principle ensures that only authorized users have access to information?

The principle that ensures only authorized users have access to information is confidentiality. This concept is fundamentally about protecting sensitive information from unauthorized access and disclosure. In cybersecurity, confidentiality safeguards means that only individuals who have been granted permissions—those who are authorized—can access specific data or resources.

Confidentiality is typically enforced through various security measures such as encryption, access controls, and authentication processes, all designed to prevent unauthorized users from obtaining sensitive information. It plays a critical role in maintaining trust and compliance, particularly in environments dealing with personal, financial, or proprietary information.

In the context of the other principles, integrity relates to the accuracy and reliability of data, ensuring that information is not altered or tampered with by unauthorized parties. Availability ensures that information and resources are accessible to authorized users when needed. Accountability involves tracking user activities to ensure that actions can be traced back to responsible individuals. While each of these principles is vital in a comprehensive cybersecurity policy, confidentiality specifically addresses the issue of who can access the information, making it the correct answer for this question.
