Time synchronization: 1 control for Linux hardening

Pavois audits 1 control in the Time synchronization hardening domain, across 9 systems and 5 standards (CIS, ANSSI BP-028, NIST 800-53, PCI DSS, DISA STIG). Every control declares the evidence it gathers, its severity, its remediation and its standard references.

This domain is thinly covered by Pavois today, see the Coverage page.

What does Pavois check in this domain?

effective runtime 1
Checked against the resolved running state (e.g. sshd -T, sysctl, systemctl show), catches drop-ins and Includes a file read would miss. Caveat: runtime ≠ persistence; a value correct now may not survive a reboot.

Which standards does this domain cover?

One effective-configuration check serves as evidence for several standards at once. The references below are the ones the corpus actually carries, never a claimed equivalence. how to read a standard mapping.
