Which components are necessary for an employee's computer in a remote access VPN using SSL VPN with PKI authentication?

Which of the following MUST be installed on an employee's computer if the remote access VPN implements an SSL VPN with PKI authentication?

A.

Shared secret

B.

C.

Soft token

D.

Private certificate.

D.

The correct answer is D. Private certificate.

An SSL VPN (Secure Socket Layer Virtual Private Network) is a type of VPN that uses SSL/TLS protocols to provide secure remote access to a network. The SSL VPN implementation with PKI (Public Key Infrastructure) authentication uses digital certificates to authenticate the remote access user.

To establish a secure connection, both the client-side and server-side need a digital certificate. The server-side typically uses a public certificate issued by a trusted Certificate Authority (CA) to prove its identity to the client-side. The client-side also needs a private certificate to authenticate itself to the server-side. The private certificate is installed on the employee's computer.

Therefore, to establish a connection using an SSL VPN with PKI authentication, the employee's computer must have a private certificate installed. This certificate ensures that the employee is a trusted user and can access the network securely.

Option A, shared secret, is used in a different type of VPN called IPSec VPN. HTTPS server (option B) and Soft token (option C) are not required for SSL VPN with PKI authentication.

In conclusion, if an organization implements an SSL VPN with PKI authentication, the employee's computer must have a private certificate installed to establish a secure connection.
