What is the primary purpose of authentication?

The primary purpose of authentication is to verify the identity of entities, which includes users, devices, or systems attempting to access a network or a resource. This process is crucial because it ensures that the individual or system requesting access is indeed who they claim to be. By establishing the authenticity of a user or system, organizations can effectively manage access control and protect sensitive information.

While enhancing network security, tracking user behavior, and preventing unauthorized access may also be outcomes or related aspects of a comprehensive security strategy, they are not the fundamental purpose of authentication itself. Instead, authentication serves as a critical first step that enables these other security measures to effectively function. When identities are verified accurately, it lays the groundwork for preventing unauthorized access and enhances overall network security through proper identity management.
