2.2.7 Ensure NFS and RPC are not enabled (Scored)

Level 1 - Server
Level 1 - Workstation 

The Network File System (NFS) is one of the first and most widely distributed file systems in the UNIX environment. It provides the ability for systems to mount file systems of other servers through the network.

If the system does not export NFS shares or act as an NFS client, it is recommended that these services be disabled to reduce remote attack surface.

Run the following commands to verify nfs is not enabled:

# systemctl is-enabled nfs-kernel-server 
disabled 

Verify result is not “enabled”.

Run the following commands to verify rpcbind is not enabled:

# systemctl is-enabled rpcbind
disabled 

Verify result is not “enabled”.

Run the following command to disable nfs and rpcbind:

# systemctl disable nfs-kernel-server 
# systemctl disable rpcbind
