What is a networking firewall and how does it work?
A firewall is a networking device. This device is used when building a strong networking system. The actual use of this device is to handle all the traffic entering and exiting the networking system. This flow of traffic is controlled according to the laws of security and protection that are predefined. The main role of a firewall is to behave like an obstacle to differentiate between all the interior and exterior networking systems. It also monitors the network traffic and checks whether to allow the traffic to go or block it somewhere. This task is done in different ways like packet-level processing, stateful survey, and application-level scanning. This barrier is required to block all illegal approaches toward the system and protect the system and data from all kinds of harmful attacks.
