    In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls filter traffic between two or more networks

    Firewall is actually a system of security for the computers using the network connections either for the internet or for any other purpose. It prevents the unauthorized access from any sort of private computer to your own network.

    Firewalls can be installed in the computer in both ways either as hardware or software or sometimes used as a combination. It is required for the prevention of the trespassing of ones private networking connected to the internet, especially involving the use of the intranet.

    The working criteria of the firewall is such that every data transmission of the internet first passes through the firewall system and only those messages which pass a certain security criteria are allowed to get through; otherwise the other data is blocked, making it inaccessible for the unauthorized users.

    The firewall involves several different techniques one of them is the Packet filter. This is a simple technique of security for the firewall system. It keeps a check on the packets which enter and leave your computer network and then verifies them according to rules previously defined by your network user so as to allow or reject their passage through the network. The packet filtering is transparent to the network users, but its configuration is difficult and requires professional help.

    The other firewall techniques include the Application gateway, which is targeted to specific programs such as the FTP, followed by the Circuit-level gateway which is required for the TCP and the UDP connections. And lastly the Proxy servers, which is most commonly used these days for the internet security system.

    Firewall is actually considered to be the primary and the first line of defense for the security reasons.

    Firewall used to block the certain network traffic on your server due to set of rules which you have define. It works as barrier between the trusted and un-trusted network. It is the key component which secure our server from the attack.

    Firewall management rules -

    It consist of two policies as below -

    1. Default Deny policy
    2. Default allow policy

    There are set of rules define which define which traffic to allow or which connection to allow on the server and which connection to refuse or block.

    Once you define the rule then you will need to configure the firewall on the server.

    Firewall is a term that is used to explain the protection of network traffic on your computer. One use could be to prevent "hackers" from accessing and stealing your personal computer programs.

    A firewall is software or hardware that controls the network traffic. It is a part of a computer system or network that can help prevent hackers or malicious software (such as worms) from gaining access to your computer through a network or the Internet.
