1.1.1.2 Ensure mounting of freevxfs filesystems is disabled (Scored)
Profile Applicability
Level 1 - Server Level 1 - Workstation
Description
The freevxfs
filesystem type is a free version of the Veritas type filesystem. This is the primary filesystem type for HP-UX operating systems.
Rationale
Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.
Audit
Run the following commands and verify the output is as indicated:
# modprobe -n -v freevxfs install /bin/true # lsmod | grep freevxfs <No output>
Remediation
Edit or create the file /etc/modprobe.d/CIS.conf
and add the following line:
install freevxfs /bin/true
