In networking, how does user authentication differ from device authentication?

User authentication focuses on verifying the identity of individual users attempting to access a network or system. This process typically involves checking credentials such as usernames and passwords, or other forms of identification like biometrics or security tokens. The goal is to confirm that the person seeking access is indeed who they claim to be, ensuring that only authorized individuals can access sensitive information or perform specific actions within the network.

On the other hand, device authentication is concerned with verifying the identity of the device itself rather than the user. This type of authentication ensures that the devices connecting to the network are recognized and trusted, which is crucial for maintaining network security and preventing unauthorized devices from gaining access.

The correct answer highlights that user authentication specifically aims to verify individual identities, which is a fundamental aspect of managing access control in network security. This distinction is important because effective user authentication protocols can help mitigate risks associated with unauthorized access, while device authentication plays a different, yet complementary, role in ensuring that only trusted devices communicate on the network.
