Description
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.
Rationale
The NIS service is inherently an insecure system that has been vulnerable to DOS attacks, buffer overflows and has poor authentication for querying NIS maps. NIS generally been replaced by such protocols as Lightweight Directory Access Protocol (LDAP). It is recommended that the service be disabled and other, more secure services be used
Audit

# systemctl is-enabled nis disabled
Verify result is not “enabled”.
Remediation

# systemctl disable nis
