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 dnf 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.
