The term 'firewall' is synonymous with cyber computing and technology. It is an extremely common term, and basically refers to a simple barrier that is constructed between an internal network and an outside one, in order to prevent any sort of intrusions or unauthorized access. A firewall is basically a hardware based (can also be software based) network security system that is established in order to control the incoming as well as the outgoing data packets. Now, the question that many people have in minds after reading the basic definition of a firewall is this: how does the firewall determine which data packets are malicious/ harmful and which aren't? Basically, firewalls run on an applied rule set, which means that they can only discern harmful data packets that have been previously configured to detect by the programmer.
Firewalls come in a variety of different varieties. There's the common firewall that is installed in every personal computer, which is used in order to prevent any sort of unauthorized access to the computer. The simple computer firewall comes built in with a standard operating system, such as Microsoft Windows, etc. However, the firewall that comes pre- installed on a person's computer is usually a very weak one, and can only detect only a handful of simple obstructions. In order to beef up the security on your computer, people usually have to make use of third party software programs which are firewalls that are regularly updated in order to take in to account all of the greatest threats that are being introduced daily.
When it comes to providing protection for a whole network, using a software based firewall might not be such a good idea. As a result, a hardware based firewall is used in order to make sure that all ports are carefully protected and that the network cannot be damaged by the incoming data packets. When network security is concerned, the contingencies are much greater. There are numerous ports and hosts that are open, and it is very important to ensure that data that is traveling to and from these ports is safe. That is the reason why an external hardware based firewall is installed on the network to monitor all sorts of outgoing and incoming traffic. These data packets are individually scrutinized in order to make sure that none of them are carrying harmful elements.
Once the firewall finds any sort of data packets that might contain malicious data, it automatically filters the data and denies access to the network. If the firewall is powerful enough, it is capable of detecting all sorts of anomalies within a few seconds. Large organizations and companies, which have to store thousands of gigabytes of data on their computers, usually make use of very powerful firewall systems so as to prevent access by unauthorized people and to make sure that their system remains safe and protected.
Computer users whether at home or at workplaces cannot afford to make their data vulnerable to illegal interception. Therefore, firewalls are used for protecting the data and networking device.
Firewall is a system which is specifically designed for preventing unauthorized and illegal access to and from a private internet connection especially intranets. Firewall can be a physical device or software, both are equally reliable. Firewalls are created to protect your computers and networking system from being invaded by hackers, worms and viruses. Whoever or whatever tries to breach your privacy and attack your computer through the internet is automatically blocked by a firewall. Therefore, you can refer to it as the guardian or watchdog of your networking devices and the data.
Another job of firewall is to allow you access your computer device remotely from a private network. This is done after provision of secure authentication certificate and salient login related information, which is known only to the user/administrator.
Firewalls can be in the form of software or hardware and regardless of the type their function remains the same, that is, to protect the information and computer. It is also possible that you configure a firewall system which comprises of both hardware and software. In fact, the ideal firewall setting is the one in which both hardware and software firewalls are utilized.
You can easily buy them as standalone devices however, in a majority of modern day broadband routers, these are already integrated. Typically, hardware firewalls comprise of at least four network ports through which you connect your PC. Business networking firewall solutions are especially designed to facilitate protection for large-scale corporate environments. Hardware Firewalls appear like this device in picture:
Just like any other software, you can download or buy and install this type of firewalls on your networking device. It allows you the liberty of customizing protection settings and adequate control over its data guarding features. Usually, software firewalls offer protection to your PC from unauthorized attempts of attacking and controlling it.
Firewalls monitor all the outgoing and incoming connections to and from your network. There is usually a previously set criterion through which it determines which type of computer or IP address should be allowed access to your network. According to the pre-set criteria it denies or approves IP addresses/computers. Along with monitoring, firewall keeps a log of all the data packets sent and received as well as the connection details and IP addresses. It also saves information about the blocked IP addresses with the reason for blocking them. Lastly, saving your computer, network and data from being illegally used by hackers and fraudsters and preventing viruses/worms from attacking are some of its primary functions.
There are three prominent methods which firewalls utilize for controlling the flow of traffic to and from your PC.
Packets are basically small portions of data which are analyzed by firewalls against a set of filters. Packets that get filtered are sent to the inviting system while the others are rejected.
The firewall retrieves information from the Internet and sends it to the requesting system.
This is a relatively new technique in which every single packet is not analyzed. Instead, some key portions of the data packet are compared to a database of reliable information. Information roving within and outside the firewall is observed for essential characteristics. Afterwards incoming information is also matched to these characteristics. If this comparison produces a rational match, the information given access otherwise it is rejected.
