What are the Types of Network Security Firewall?

A Network Security Firewall may be physical or software. Each computer has a programme called a software firewall that controls network traffic by using apps and port numbers. Hardware firewalls, on the other hand, are the devices installed between the gateway and your network. You can refer to a Network Security Firewall that is provided via a cloud service as a cloud firewall as well.
