The Network Information Service (NIS), formerly known as Yellow Pages,
is a client-server directory service protocol used to distribute system configuration
files. The NIS client ('ypbind') was used to bind a machine to an NIS server
and receive the distributed configuration files.
Parameter:
[no/yes]
Technical Mechanism:
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NIS generally has been replaced by such protocols as Lightweight Directory Access
Protocol (LDAP). It is recommended that the service be removed.
