But how does a firewall detect what should and should not cross the network boundary?įor this purpose, the firewall checks the data packets, including the source and destination addresses of the packets, complies with the set of rules defined for the network, and then determines whether the packet is allowed to pass. Therefore, any data must first pass through the firewall before it can reach your network from the Internet or other networks. A software or hardware firewall can be considered the first security barrier to network input. What Is A Firewall Exactly?Ī firewall is a software or hardware that, like a security fence, surrounds a network or computer system and protects them from certain cyber threats. Due to the differences between the hardware firewall and the software firewall and the advantages and disadvantages of each, both firewalls can be used in networks to compensate for the other disadvantages. The difference between software firewalls and hardware firewalls is rooted in their capabilities. Some hardware firewalls are also part of the router and are integrated into it. A hardware firewall is a standalone device with a dedicated CPU, memory, operating system, and software. Firewall software is a security software that is installed on a computer or server. Firewall models can be divided into two groups: a software firewall and a hardware firewall.
