Which principle in cybersecurity is concerned with protecting data from unauthorized access?

The principle concerned with protecting data from unauthorized access is confidentiality. In the realm of cybersecurity, confidentiality refers to measures that ensure sensitive information is accessed only by those who are authorized to do so. This is achieved through various strategies, including encryption, access controls, and authentication protocols.

Confidentiality is vital for maintaining the privacy of individuals and organizations, as well as for compliance with regulations that govern data protection. By focusing on confidentiality, organizations aim to prevent data breaches where unauthorized individuals may gain access to, read, or manipulate sensitive information.

The other principles, while essential components of a comprehensive cybersecurity strategy, address different aspects of data protection. Integrity relates to the accuracy and reliability of data, ensuring that information is not altered or tampered with. Availability focuses on ensuring that data and systems are accessible to authorized users when needed. Accountability involves tracking user actions to ensure that individuals can be held responsible for their behaviors regarding data access and handling. Each principle is interconnected, but confidentiality specifically targets the protection of data from unauthorized access.
