The primary function of a network firewall is to control incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a predetermined set of security rules. This provides a barrier between a secured and controlled internal network that can be trusted and an untrusted outside network, such as the internet.
