Ensure NIS Server is not enabled

中级别 1自动化ros

说明

The Network Information Service (NIS) (formally known as Yellow Pages) is a client-server directory service protocol for distributing system configuration files. The NIS server is a collection of programs that allow for the distribution of configuration files. The audit requires the NIS server unit(s) nis not to be enabled or active (systemctl). Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
