Network Time Security (NTS) support for Network Time Protocol (NTP) (EX Series, MX Series, NFX Series, PTX Series, QFX Series, and SRX Series)—Starting in Junos OS Release 21.3R1, NTS provides cryptographic security for network time synchronization and supports the client/server mode of NTP. NTS uses the Transport Layer Security (TLS) protocol and Authenticated Encryption with Associated Data (AEAD) to obtain network time in an authenticated manner.
NTS provides strong cryptographic protection against wide range of security attacks such as packet manipulation, spoofing, DDOS amplification attacks, and replay attacks. NTS also provides scalability as servers can serve several clients without the need for any manual client-specific preconfiguration.
