cyberstrikeus 2.19 Disable Mounting of freevxfs Filesystems (Not Scored)
Profile Applicability
- Level 2
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 server. If this filesystem type is not needed, disable it.
Audit Procedure
Using Command Line
/sbin/modprobe -n -v freevxfs
/sbin/lsmod | grep freevxfs
Expected Result
The first command should output install /bin/true. The second command should produce no output (module not loaded).
Remediation
Using Command Line
Edit or create the file /etc/modprobe.d/CIS.conf and add the following line:
install freevxfs /bin/true
Default Value
By default, the freevxfs module is available for loading.
