Ensure NFS and RPC are not enabled

MittelStufe 1Automatisiertros

Beschreibung

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. The audit requires the NFS/RPC unit(s) nfs-server, rpcbind not to be enabled or active (systemctl). Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
