Title : Port Randomization in the Network Time
Protocol Version 4

Pages : 10

Abstract:
The Network Time Protocol can operate in several modes. Some of
these modes are based on the receipt of unsolicited packets, and
therefore require the use of a well-known port as the local port
number. However, in the case of NTP modes where the use of a well-
known port is not required, employing such well-known port
unnecessarily increases the ability of attackers to perform blind/
off-path attacks. This document formally updates RFC5905,
recommending the use of transport-protocol ephemeral port
randomization for those modes where use of the NTP well-known port is
not required.
