AlmaLinux OS 9 must disable remote management of the chrony daemon.

Not exposing the management interface of the chrony daemon on the network reduces the attack surface.

Verify AlmaLinux OS 9 disables remote management of the chrony daemon with the following command:

$ chronyd -p | grep -w cmdport

cmdport 0

If the "cmdport" option is not set to "0" or is missing, this is a finding.

Configure AlmaLinux OS 9 to disable remote management of the chrony daemon by adding/modifying the following line in the /etc/chrony.conf file:

cmdport 0
