What is a firewall?
In fact, firewalls are network security systems that control traffic flow between the Internet and the private network; it also protects a system from illegal access and provides high network security for the system; there are three basic types of firewalls, each of which are going to be briefly described below.

These types of firewalls, compared to other types, have less ability to provide security for the network and analyze all the data that enters or exits the system, and in case of suspicious activity, the data is not allowed to enter the system.
In fact, these types of firewalls are suitable for small networks and do not have a high ability to increase network security for large companies.
The things that firewalls protect the system and information from:
There are different types of firewalls, and each of them protects the computer system against different factors; firewalls detect unauthorized traffic and prevent any further damage quickly.
