Install tcp_wrappers Package

An XCCDF Rule

Description

When network services are using the xinetd service, the tcp_wrappers package should be installed. The tcp_wrappers package can be installed with the following command: 
$ sudo zypper install tcp_wrappers

Rationale

Access control methods provide the ability to enhance system security posture by restricting services and known good IP addresses and address ranges. This prevents connections from unknown hosts and protocols.
