A firewall normally establishes a barrier between an untrusted remote network and a trusted local network, like the Internet. Firewalls prevent unauthorized access by controlling the communication between two or more networks.

There are many factors that determine firewalls security requirements. One of these is the type of network that the firewall is used for managing. Another factor that greatly influences the firewall’s security requirements is the types of information that need to be managed or protected.
