In other words, it acts as a barrier for keeping away the destructive forces from the server that might be loading the server. In case you do not wish to eternal users to access a specific service or host, you can make use of firewall.

There are various uses of firewall: first, it is used for filtering packets based on IP address sources; Second it is used to secure the server and protect data from being get hacked; Third is that it is most commonly used for preventing denial of service attack, your server can be prevented from a definite level of DDOS attacks.

Firewall can be also considered a device or a program that controls and monitors all data transfer between whole internets with any internal network. It also makes sure that every communication of data in both directions is according to the set rules of security.

The technologies of firewall are configurable, hence via, IP address, ports, protocol, direction, or many other combinations, the communication can be limited. A communication failure can occur in case the data communication is not set according to rules of incoming and outgoing requests. In case, there is an access to the firewall of your server, an individual can configure it for enabling the protocols, ports and addresses that might optimize the communication of data.

The firewall can be configured to permit the TCP traffic only for security reasons that might cause the user to view buffering of clips frequently. The experience of the presentation for users is compromised, greater startup times and latency affect the time required for viewing the clip and more total bandwidth is required for delivering the clip.

There are various kinds of firewall some of the general ones are given below:
Software Firewall: It is a software application that can be installed on a server that is able to prevent the data communications that are not wanted. The various webmasters do not find the software firewall to be the secure one. This kind of firewall is used often as an application firewall means it is optimized for protecting applications like email servers and web application. Every software firewall has filters that are built-in-complex for examining the network traffic content.

Desktop firewall: Approximately every operating system has applications of built-in-firewall that is responsible to protect the machine standalone. It is designed for protecting a single desktop computer and is a mechanism of great protection in case, there is a compromise on the network firewall.

Hardware firewall: It is a hardware device that is dedicated and is installed on the server or system. This kind of firewall has a network router that has additional capability of firewall. It is usually designed for handling the network traffic sites that are heavy. These firewalls are usually kept on the perimeter of the network for filtering the noise of internet and permit only the pre-determined traffic into the network.
