NTP client synchronizes to authenticated NTP servers to ensure that time service is reliable across the network. Authentication prevents the modification of NTP message data from malicious network attacks.
By configuring the authentication key ID used in the synchronization with the specific NTP server on the NTP client, you can apply NTP authentication in client/server mode.
By configuring the authentication key ID used in the synchronization with the NTP broadcast server on the local FW, you can apply NTP authentication in broadcast mode.
By configuring the authentication key ID used in the synchronization with the NTP multicast server on the local FW, you can apply NTP authentication in multicast mode.
By configuring the authentication key ID used in the synchronization with the NTP manycast client on the local FW, you can apply NTP authentication in manycast mode.
