Transcribed: What is the major function of a firewall? I'm working on packet filtering software. What are the ground rules that I must adhere to?

Answer

The computer firewall safeguards our computer system against hackers.

Packet filtering is the principal function of a firewall.

When a computer transmits a request across the Internet, it does so as a tiny packet of data.

These data packets proceed to their destination across the network.

If the firewall determines that the packet is not permitted.

The data is discarded.

In a software firewall, packet filtering is accomplished by a program known as a packet filter.

Packet filtering is a component of a firewall application that protects a network against unauthorized access.

The packet filter rules must be followed to either permit or deny packets.

You may configure a rule to deny packets.
