Uninstall ypserv Package

An XCCDF Rule

Description

The ypserv package can be removed with the following command:

$ sudo zypper remove ypserv

Rationale

The NIS service provides an unencrypted authentication service which does not provide for the confidentiality and integrity of user passwords or the remote session. Removing the ypserv package decreases the risk of the accidental (or intentional) activation of NIS or NIS+ services.
