What principle emphasizes the importance of user authentication?

User authentication is fundamentally linked to the principle of confidentiality. Confidentiality entails ensuring that sensitive information is accessed only by authorized individuals. Through robust user authentication measures, organizations verify the identity of users before granting them access to sensitive data or systems. This process helps to protect confidential information from unauthorized access, thereby maintaining the privacy and integrity of the data.

For instance, implementing multi-factor authentication (MFA) enhances the security of user accounts by requiring additional verification methods beyond just a password. This prevents unauthorized users from compromising confidential information, which aligns with the overarching goal of maintaining confidentiality within a cybersecurity framework.
