If the system is not a Domain Name Server (DNS), it should not have a DNS server package installed to decrease the attack surface of the system.

Check Content

Verify RHEL 10 does not have a DNS package installed with the following command:

$ sudo dnf list --installed unbound

Fix Text

Configure RHEL 10 to not have the unbound package installed with the following command:

$ sudo dnf -y remove unbound
