The purpose of authentication in information security is fundamentally to verify the identity of users and devices. This process ensures that the party attempting to access a system, application, or network is indeed who they claim to be. By implementing effective authentication measures, organizations can prevent unauthorized access to sensitive information and resources.

When users authenticate through methods such as passwords, biometrics, or multi-factor authentication, the system can validate their identity before granting access. This is essential for maintaining the confidentiality and security of information systems, as well as establishing accountability for actions performed within those environments.

While tracking user activities, enforcing security policies, and maintaining data integrity are important aspects of an overall security strategy, they are not the primary focus of authentication. Authentication specifically addresses the identification and verification of users and devices to facilitate secure access.
