A Brief Explanation on Features and Advantages of Firewall

The group of the system, which sets the security rules to control the access of two networks so as to protect the inside and outside of the network, is called firewall. It may be in form of hardware or software. Software program is run by a host PC, which is well secured. In both the cases at least two networks are required. 

 

Out of these two, one should be protected and other should be exposed one. The function of the firewall is to sit at the junction point of the two networks. Mostly, this is required in private networks rather than public networks like internet. There are many kinds of firewall techniques like Application gateway, Circuit-level gateway, Packet filter and Proxy server. 

Distribution of firewall

It is the host resident security software, which helps in protection of the enterprise server’s network as well as end user machines from the intrusion, which is unwanted. The Firewall actually reduces and filters the internet as well as internal network’s traffic and hacking attacks. All the features of the firewall are well managed. Hence, it helps to increase the limited resources. It even gathers and maintains report and their updates and is distributed securely. 

 

It helps in two ways. Firstly, it secures the end user machines. Secondly, with the help of codes and jailing it secures the critical servers. The most conventional of them are dependent on the restricted topology’s notions and even it controls all the points of entry. It depends upon the assumption that one side of the firewall is the entry point and can be trusted while the other side of the firewall does not have any potential and is an enemy. 

 

However, the following problems were faced by the conventional type of firewall. Firstly, as the line speeds are increasing, the firewall has to be supported. Nowadays, even the gap between the speed of networking and processing is increasing.

Firewall is more often the application of the kernel mode that is placed at the last of the OSI row or stack in an operating system and this filters all the traffic without even knowing its origin either that’s internet or internal network. Firewall considers both of them unfriendly. 

 

Firewall actually works on the following three terms and conditions number one the language of the policy, which tells about the connections to be prohibited or banned and to be permitted or allowed. Number two notion says about the number of tools for system management for example Microsoft SMS etc and the third notion states about the encryption mechanism at the network level for IP or TCP.

Following are the components of the firewall

1. For designing the policies there is a central managing system. This makes it possible to give security to wide range of severs.

2. To transmit the above policies there is a transmission system. It makes sure about the integrity of the policy.

3. The client implements the above designed and transmitted policies. The host only provides the traffic based security.
