Uninstall dnsmasq Package

An XCCDF Rule

Description

dnsmasq is a lightweight tool that provides DNS caching, DNS forwarding and DHCP (Dynamic Host Configuration Protocol) services.
The dnsmasq package can be removed with the following command: 

$ sudo yum erase dnsmasq

Rationale

Unless a system is specifically designated to act as a DNS caching, DNS forwarding and/or DHCP server, it is recommended that the package be removed to reduce the potential attack surface.
