Question
A technician is deploying a new Wi-Fi solution for the office and wants to ensure users can log in to the Wi-Fi with their existing network log-in and password. Which of the following methods should the technician use?
A. AES
B. RADIUS
C. TKIP
D. WPA3
Answer
B. RADIUS
Explanation
To allow users to log in to the office Wi-Fi using their existing network username and password, the technician should implement RADIUS (Remote Authentication Dial-In User Service) authentication.
RADIUS is a centralized authentication, authorization, and accounting protocol that enables secure user authentication for network access. When RADIUS is set up for Wi-Fi, it allows users to enter their regular network login credentials to connect to the wireless network, rather than having to remember a separate Wi-Fi password.
Here’s how RADIUS authentication works for Wi-Fi:
- The user attempts to connect to the Wi-Fi network and is prompted to enter their username and password.
- The wireless access point (AP) forwards the user’s credentials to the RADIUS server for authentication.
- The RADIUS server checks the credentials against the user database (e.g., Active Directory) and sends an accept or reject message back to the AP.
- If the credentials are valid, the user is granted access to the Wi-Fi network. If not, access is denied.
RADIUS offers several benefits, including:
- Centralized user management: User accounts can be managed in one place (e.g., Active Directory), simplifying administration.
- Enhanced security: RADIUS supports strong authentication methods like EAP (Extensible Authentication Protocol) and can integrate with multi-factor authentication solutions.
- Logging and accounting: RADIUS can log authentication attempts and track user activity for auditing and compliance purposes.
The other options mentioned (AES, TKIP, WPA3) are encryption protocols used to secure Wi-Fi data transmission, but they do not provide user authentication like RADIUS does.
In summary, to allow users to log in to the office Wi-Fi with their existing network credentials, the technician should implement RADIUS authentication. This will provide a secure and user-friendly Wi-Fi access solution.
