Discover the definition of the term Ntp (Network Time Protocol) presented by Les Assises de la Cybersécurité.

NTP (NETWORK TIME PROTOCOL)

NTP is a network protocol responsible for ensuring time synchronization across a network. But why talk about time in cybersecurity? Because access to a specific time is an essential condition for the proper functioning of “One Time Password” authentication, in which passwords have a limited lifespan. The time must be synchronized very precisely between the authentication infrastructure and the remote devices displaying the one-time passwords. During digital investigations, it is also important to have reliable and harmonized times across all event logs in order to be able to follow the intruder’s tracks.

Poor time synchronization changes the authentication method from “OTP” to “OQP” (we must admit that geek jokes are not always the best…).
