What aspect of cybersecurity is primarily concerned with protecting data from unauthorized access or corruption?

The aspect of cybersecurity that focuses on protecting data from unauthorized access or corruption is confidentiality. Confidentiality ensures that sensitive information is only accessible to those individuals who are authorized to access it. This involves implementing measures to prevent unauthorized users from viewing or modifying the data, thereby maintaining its privacy and security.

Confidentiality can be achieved through various means, including encryption, access controls, and identity management systems, all designed to keep data secure from potential threats.

While availability refers to the assurance that data and services are accessible to authorized users when needed, and integrity pertains to the accuracy and trustworthiness of data, confidentiality specifically addresses the prevention of unauthorized access. Authentication, on the other hand, relates to verifying the identities of users or systems instead of safeguarding the data itself. By focusing on confidentiality, organizations can safeguard sensitive information from breaches and ensure that it remains protected from unauthorized modifications or access.
