+== UFW Lab ==
+=== Introduction ===
+''' UFW (uncomplicated firewall) ''' is a firewall configuration tool that runs on top of iptables, included by default within Ubuntu distributions. It provides a streamlined interface for configuring common firewall use cases via the command line.
+
+'''Verify UFW Status''' 
+
+To check if ufw is enabled, run:
+{{{
+sudo ufw status
+}}}
+
+''' Enable UFW '''
+
+If you got a '''Status: inactive''' message when running ufw status, it means the firewall is not yet enabled on the system. You’ll need to run a command to enable it.
+{{{
+sudo ufw enable
+}}}
+You’ll see output like this:
+{{{
+Output
+Firewall is active and enabled on system startup
+}}}
+
+'''Disable UFW'''
+
+If for some reason you need to disable UFW, you can do so with the following command
+{{{
+sudo ufw disable
+}}}
+Be aware that this command will fully disable the firewall service on your system.
