George use to protect the network of the company from intrusion?

Answer:

Explanation:

A firewall is a set of related programs configured to protect private networks connected to the
Internet from intrusion. It is used to regulate the network traffic between different computer
networks. It permits or denies the transmission of a network packet to its destination based on a
set of rules. A firewall is often installed on a separate computer so that an incoming packet does
not get into the network directly.
