What is a Firewall?

A firewall is a layer of Security that controls network security, which means incoming and outgoing traffic. A firewall is implicitly denied by default. You just need to open the ports that you need.

  • Each rule can be either Ingress or Egress.

  • Using firewall rules either you can allow or deny connections.

  • You can allow traffic from the internet or internal traffic.

Lab Tasks:

  1. Create a firewall rule to allow egress of all traffic.

  2. Create a firewall rule to allow ingress SSH traffic only.
