Firewalls act as a barrier between different parts of the network, and they can be configured to control and filter traffic based on defined security rules and policies. The primary purpose of a firewall between internal network segments is to inspect and control the flow of traffic, thereby enhancing security and reducing the risk of unauthorized access or malicious activity between network segments.
