Description
The rcnfs entry starts the NFS daemons during system boot.
NFS is a service with numerous historical vulnerabilities and should not be enabled unless there is no alternative. If NFS serving is required, then read-only exports are recommended and no filesystem or directory should be exported with root access. Unless otherwise required the NFS daemons (rcnfs) will be disabled.
ℹ️ Check
From the command prompt, execute the following command:
# lsitab rcnfs
If the command yields any output, this is a finding.
✔️ Fix
In "/etc/inittab", remove the "rcnfs" entry by running the following command:
# rmitab rcnfs
To request the init command to re-examine the "/etc/inittab" file, enter:
# telinit q
