A Firewall is a device or software system that filters the data & information exchanged between different networks by enforcing the access control policy of the host network.
A firewall monitors & controls access to or from protected networks. People (remote users) who do not have permission cannot access the network, and those within cannot access sites outside the network restricted by firewalls.
