A firewall is a fundamental security tool that is used to filter traffic on a network.

A firewall is a fundamental security tool that is used to filter traffic on a network. Firewalls can be used to separate network nodes from external traffic sources, internal traffic sources, or even specific applications. Firewalls can be software, hardware, or cloud-based. Read below for a brief description of each:

Software firewalls include any type of firewall that is installed on a local device rather than a separate piece of hardware (or a cloud server).
Hardware firewalls use a physical appliance that acts in a manner similar to a traffic router to intercept data packets and traffic requests before they’re connected to the network’s servers.
Whenever a cloud solution is used to deliver a firewall, it can be called a cloud firewall, or firewall-as-a-service (FaaS).
Now assume you want to start your own business at your home. You need to build your home computer network for your business. Address the following questions:

Do you want to setup a firewall for your home business? Why or why not?
