What is the purpose of authentication in a network?

The purpose of authentication in a network is to verify the identity of a user or device before granting access to resources. This process is essential for maintaining the security and integrity of the network, as it ensures that only authorized individuals or devices can connect and interact with the system. By confirming identities through methods such as passwords, biometrics, or security tokens, the network can prevent unauthorized access and protect sensitive data.

Creating user accounts, managing data backups, and configuring network settings are important tasks in network management, but they do not directly relate to the core function of authentication. While user account creation is part of the overall authentication process, it is the verification of identity that is fundamental to ensuring secure access within the network.
