    The importance of having firewalls! Firewall is a software or hardware device that protects your computer from being attacked over the internet by hackers, viruses, and worms. This may occur either at a large corporate network, or simply at a small home network; both have the same security issues.

    A firewall is a system that provides network security by filtering incoming and outgoing network traffic based on a set of user-defined rules. We can use the firewall for reduce or eliminate the occurrence of unwanted network communications while allowing all legitimate communication to flow freely and It provide an essential layer of security that, combined with other measures, prevent attackers from accessing your servers in malicious ways.

    An Internet firewall is important for many reasons. Some value a firewall for its ability to keep private information secure. Identity theft is a growing crime and many see firewalls as a good defense against these specific types of predators. Others, such as small business owners, think firewalls are important because a firewall keeps all their personal electronic information private. Not only is privacy important from a competitive perspective, but you must make certain that you can assure your customers that their personal business information is going to be safe with you.

    Firewall is used to define the set of rules for network traffic. It is either software or hardware. It stops the un-trusted traffic. You can define set of rules in your way so you can stop the attacks or hack attempts on your server.

    If your servers's bandwidth is utilized by the un-authorized IP addresses then you can block such traffic. You can block the particular port in the firewall so no one can access it.

    You have option to allow IP or deny IP in firewall that is either allow those IP addresses to access your network or particular port or disallow them to access them some features on the server. The blocks will be automatically removed after some time as per the rule set in firewall.

    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.

    Firewall is the best option to secure your server.
