A Firewall is a security measure for a network that is available in both hardware as well as software or even both that screens network traffic whether it be going to or from the network, and then proceeds to allow or block certain traffic that has been defined in a set of security rules. This protects the network by setting up a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks.
