Term 723
Network Time Protocol is a networking protocol used to synchronize the clocks of computers and devices over a network to a common time reference.
Term 724
NTP Authentication is a security feature that ensures a network device only synchronizes its clock with trusted time servers by using encrypted keys to verify the identity of the time source.
Term 725
The NTP (Network Time Protocol) Client and Server are roles in a time synchronization system where the server provides accurate time to clients, ensuring all devices on a network share the same precise clock.
Term 726
NTS (Network Time Security) is a cryptographic protocol that secures NTP time synchronization against tampering and delay attacks.
Term 727
