TOSS 5 must disable network management of the chrony daemon.

Rule version TOSS-05-000203 · STIG v1 · 2026-08-20

Discussion

Not exposing the management interface of the chrony daemon on the network diminishes the attack space.

Satisfies: SRG-OS-000095-GPOS-00049, SRG-OS-000096-GPOS-00050

Check

Verify TOSS 5 disables network management of the chrony daemon using the following command:

$ grep -w cmdport /etc/chrony.conf

cmdport 0

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

Fix

Configure TOSS 5 to disable network management of the chrony daemon by adding/modifying the following line in the "/etc/chrony.conf" file:

cmdport 0
