What does confidentiality in cybersecurity focus on?

Confidentiality in cybersecurity specifically emphasizes protecting information from unauthorized access. This means ensuring that only individuals or systems that have been granted permission can view or use certain data. The primary goal is to safeguard sensitive information, so it is kept private and secure from malicious actors or unintended users. Implementing access restrictions for unauthorized users is fundamental to maintaining confidentiality, as it controls who can interact with information and prevents breaches.

In contrast, the other choices focus on different aspects of cybersecurity. While availability pertains to ensuring that authorized users can access information when needed, and data integrity involves verifying that information has not been altered or tampered with, these concepts are separate from the primary aim of confidentiality. User authentication processes also relate to how users are verified before gaining access but are more about assurance of identity rather than the broader concept of maintaining confidentiality of data.
