I use Fedora 28 and I don't know whether there's firewall on my laptop.

How can I know there's firewall installed?

If it's not then how can I install and configure it.

Thank you very much for the help and Great day.

Fedora 28 ships with Firewalld pre-installed.
The firewall is active and running by default.
Learn how to use it : Fedora WIKI Firewalld
Here are the commands to verify the status :

$ sudo dnf list installed | grep firewalld
firewalld.noarch                     0.5.3-2.fc28                    @updates
firewalld-filesystem.noarch          0.5.3-2.fc28                    @updates

$ sudo firewall-cmd --state
running  

$ sudo systemctl status firewalld

If you want to configure the firewall via GUI :

sudo dnf install firewall-config

You can check what's installed and available :

$ sudo dnf list firewall*

Are users advised to make further configuration changes to firewalld? I'm used to Ubuntu's ufw where I would just do sudo ufw enable and forget about it since it would by default drop all incoming connections and only allow outgoing connections.

@mb3 If you don't want to adjust something special, there is nothing you need to do - everything is setup out-of-the-box. The difference compared to Ubuntu is that the firewall is enabled and running by default. :)
