Configuring NTP Security Mechanisms

Setting NTP Access Authorities

This section describes how to configure access permission control to restrict certain NTP requests.

Enabling NTP Authentication

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.

Configuring NTP Authentication in Unicast Client/Server Mode

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.

Configuring NTP Authentication in Peer Mode

By configuring the authentication key ID used in the synchronization with the peer on the local end, you can apply NTP authentication in peer mode.

Configuring NTP Authentication in Broadcast 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.

Configuring NTP Authentication in Multicast 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.

Configuring NTP Authentication in Manycast 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.
