How does WPA2/3-Enterprise authentication function?

1. It relies on a single password for all users

2. It authenticates users individually through a server

3. It uses a static IP address for identification

4. It prevents access points from communicating

The correct answer is: It authenticates users individually through a server

WPA2/3-Enterprise authentication functions by authenticating users individually through a centralized authentication server, typically employing the IEEE 802.1X protocol. This model enhances network security by requiring each user to provide their unique credentials, which are verified against a database managed by the authentication server (like a RADIUS server). This individualized authentication process allows network administrators to have greater control over who accesses the network. They can easily manage user access, revoke credentials, and implement various security policies. As opposed to a shared password, which could be disseminated and become less secure over time, the enterprise model utilizes unique credentials for each user session. This ensures that only authorized users can access the network, enhancing both security and accountability. In contrast, relying on a single password for all users would lead to significant security risks. Using a static IP address for identification does not directly relate to the authentication method itself, as IP addresses can be easily spoofed or manipulated. Preventing access points from communicating would also conflict with the operational requirements of a wireless network. Thus, the approach of authenticating users individually is a fundamental aspect of WPA2/3-Enterprise, promoting a secure and manageable network environment.
