What is a Firewall?
So basically a system which is specifically designed to prevent any unauthorized access from a private network or to a private network is a Firewall. As we all aware of the fact that all the communication that we do goes through a firewall as it is present in our computer network and the internet.
But why do we need a firewall at first hand?
When you connect your various devices through an internet connection, this makes you vulnerable to hackers who want to get access to your financial or personal information. Not only may this some of them want to steal your internet connection to send worms, viruses and other malicious threats to malign your reputation.
So here the role of firewall become eminent as it provides safety by acting as a shield between the internet and our computer. Whenever you connect your device to the internet you start exchanging information. A firewall inspects all the information and blocks the one which does not meet the security criteria. There is a number of threats against which the firewall provide security including viruses, Trojan backdoors, session hijacking and many others.
How many types of firewall are there?
The main firewall protection can be categorized into two main categories including software and hardware.
The firewall in the form of hardware can be a router or any tangent security product which can be placed on your computer and the outside world. You can attach more than one device with the device, and each device will separately be monitored and protected by the firewall device.
The other form of firewall is software. In the software form, a firewall is installed on your computer and provides you protection against any intruder or malicious information transfer.
Types of firewall:
To protect your valuable data on the internet and prevention of unauthorized access, various types of firewall techniques are available.
- Proxy Server:
Proxy server hides the actual address of the network. Furthermore, it investigates all the messages leaving and entering the network.
- Circuit-level Gateway:
For TCP and UDP connections circuit level gateway is used. However, when a secure connection has established between the hosts, the information in the form of data packets flow without further scrutiny.
- Packet Filter:
A packet filter firewall is the one who inspects every data packets which leave or enter the network.
- Application Gateway:
For certain specific applications, we use the application gateway mechanism. However, one of the drawbacks of such security is that it affects the performance of the system by making it slow.
- Next Generation Firewall (NGFW)
An entirely new form of firewalls is the next generation firewall which inspects and filter all the traffic based on the traffic type by using several specific ports. For providing smart protection, the next generation firewalls combines the basic functions of a standard firewall with the quality of service.
