The freevxfs filesystem type is a free version of the Veritas type filesystem. This is the primary filesystem type for HP-UX operating systems.
Options Explained:
disable - would disable the module.
disable with error logged - would disable the module and log whenever module is inserted.
enable - would enable the module.
Rationale:
Removing support for unneeded filesystem types reduces the local attack surface of the server. If this filesystem type is not needed, disable it.
Fix:
Edit or create the file /etc/modprobe.d/freevxfs.conf and add the following line:
install freevxfs /bin/true
Parameter:
[disable/disable with error logged/enable]
Technical Mechanism:
Edit or create the file /etc/modprobe.d/freevxfs.conf and add the following line:
install freevxfs /bin/true
