Discussion

If Network Time Protocol (NTP) is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps inaccurate and affect scheduled actions. NTP authentication is used to prevent this tampering by authenticating the time source.

Check Content

Use "cluster time-service ntp server show" to see authenticated NTP sources using authentication that is cryptographically based.

If any of the NTP servers listed has the field "Is Authentication Enabled" set to false, this is a finding.

Fix Text

Configure an authenticated NTP source using authentication that is cryptographically based with "cluster time-service ntp server create -server <ip_address> -key-id <NTP_Symmetric_Authentication_Key_ID>".
