| 2 | # |
| 3 | # Description |
| 4 | # =========== |
| 5 | # The freevxfs filesystem type is a free version of the Veritas type |
| 6 | # filesystem. This is the primary filesystem type for HP-UX operating systems. |
| 7 | # |
| 8 | # Rationale |
| 9 | # ========= |
| 10 | # Removing support for unneeded filesystem types reduces the local attack |
| 11 | # surface of the system. If this filesystem type is not needed, disable it. |
| 12 | # |
| 13 | # Audit |
| 14 | # ===== |
| 15 | # Run the following commands and verify the output is as indicated: |
| 16 | # |
| 17 | # # modprobe -n -v freevxfs |
| 18 | # install /bin/true |
| 19 | # # lsmod | grep freevxfs |
| 20 | # <No output> |
| 21 | # |
| 22 | # Remediation |
| 23 | # =========== |
| 24 | # Edit or create the file /etc/modprobe.d/CIS.conf and add the following line: |
| 25 | # |
| 26 | # install freevxfs /bin/true |
| 27 | # |
