A. For a stronger authentication, you can also enable extended authentication (XAuth) to request the remote peer to provide a username and password.
B. FortiGate supports pre-shared key and signature as authentication methods.
C. Enabling XAuth results in a faster authentication because fewer packets are exchanged.
D. A certificate is not required on the remote peer when you set the signature as the authentication
method.
Explanation:
A. For a stronger authentication, you can also enable extended authentication (XAuth) to request the remote peer to provide a username and password.
B. FortiGate supports pre-shared key and signature as authentication methods.
A. XAuth provides an additional layer of authentication by requiring the remote peer to provide a username and password in addition to the pre-shared key or certificate. This enhances security.
B. FortiGate supports both pre-shared key and signature (using certificates) as authentication methods for IPsec VPN connections, offering flexibility based on security requirements.
C. Enabling XAuth does not necessarily result in faster authentication because additional packets are exchanged to complete the XAuth process.
D. When using the signature as the authentication method, a certificate is required on the remote peer for authentication, ensuring secure communication.
To authenticate each other, the peers use two methods: pre-shared key or digital signature. You can also enable an additional authentication method, XAuth, to enhance authentication.
