    In the computing world, the terminology firewall security refers to a network device which blocks certain kinds of network traffic. Actually, it acts as a barrier between a trusted and an untrusted network. The firewall security wall can be compared to a physical firewall in the sense that firewall security tries to block the spread of computer attacks.

    Today, businesses have understood the need for firewall security, thereby they have firewall protection in place.

    Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.

    A firewall can be hardware, software, or both.
