Question

Beatrix plans to implement an authentication server at an organization. The server needs to authenticate network devices and send communications in an encrypted manner. Which of the following would you recommend?

a. RADIUS
b. EAP
c. TACACS+
d. Kerberos

Answer 1

I would recommend RADIUS, TACACS+, or Kerberos for implementing an authentication server that authenticates network devices and sends communications in an encrypted manner.

Step-by-step explanation:

For implementing an authentication server that authenticates network devices and sends communications in an encrypted manner, I would recommend RADIUS, TACACS+, or Kerberos.

1. RADIUS (Remote Authentication Dial-In User Service) is a widely-used authentication protocol that provides authentication, authorization, and accounting services. It is commonly used in wireless networks and supports encryption through protocols like EAP (Extensible Authentication Protocol).
2. TACACS+ (Terminal Access Controller Access Control System Plus) is another popular authentication protocol that provides similar services to RADIUS, but offers more features and capabilities. It also supports encryption and is commonly used in enterprise networks.
3. Kerberos is a network authentication protocol that uses tickets to authenticate users and secure their communications. It is commonly used in Windows environments and supports encryption.

Ultimately, the choice between these protocols would depend on the specific requirements and compatibility with the organization's network devices and infrastructure.
