Hardening (posture): 13 controls for Linux hardening
Pavois audits 13 controls in the Hardening (posture) hardening domain, across 9 systems and 1 standard (NIST 800-53). Every control declares the evidence it gathers, its severity, its remediation and its standard references.

What does Pavois check in this domain?
- effective runtime 8
- 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.
- inventory state 3
- Checked against what is installed or registered, packages present/absent, account databases.
- persistent config 2
- Checked against the content of a persistent configuration file, the source of truth that survives reboots.
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.
