    Firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic based on applied rule set. A firewall establishes a barrier between a trusted, secure internal network and another network that is not assumed to be secure and trusted

    Hello
    A firewall is a set of relevant programs, situated at a network gateway server, that defends the sources of a private network from users from other networks.

    A firewall is software or hardware that checks information coming from the Internet or a network, and then either blocks it or allows it to pass through to your computer, depending on your firewall settings.

    A firewall can help prevent hackers or malicious software (such as worms) from gaining access to your computer through a network or the Internet. A firewall can also help stop your computer from sending malicious software to other computers.

    The following illustration shows how a firewall works.

    Just as a brick wall can create a physical barrier, a firewall creates a barrier between the Internet and your computer
    A firewall isn't the same thing as an antivirus program. To help protect your computer, you need both a firewall and an antivirus and anti-malware program.
