DNS Firewall

Firewall has been one of the integral parts of the Internet and is quite an old concept. It prevents any unauthorized access and protects the user from various attacks.

Right from the time of inception DNS has been treated as an unalterable protocol that has to be maintained in the purest format. Since DNS is essentially a vast directory of the websites available on the Internet, almost no one thought of modifying it in any way. However, this left this highly valuable resource practically defenseless against any exploit. Normal firewall is worthless to protect DNS. This is known by the cyber criminals and thus most of the major attacks are targeted on the DNS. This has resulted in the growing need of a specialized firewall for the protection of DNS, also known as DNS Firewall.

DNS firewall is highly important keeping in view the evolving techniques various hackers are using to gain access to confidential data of the users. DNS firewall is essentially a secured DNS resolver. This checks the origin of any query and in case of bots trying to gain access to confidential data or unauthorized regions of the DNS server. This firewall not only protects the database from external attacks, but also ensures that those who are operating within the network do not fall prey to any malicious link exploit. It prevents the user from within the network to visit any link that can jeopardize the security and integrity of the entire network. All it takes is a list of all the recognized malicious websites and the firewall will prevent users from visiting such websites.

The major advantage of having DNS firewall is that it is not too costly to implement or maintain. It is essentially software that is operating within the network. Since the software can be simply upgraded, addition of newly discovered malicious sites will only take updating the already installed database of malicious sites.

It's important of DNS Firewall adoption even a major giant like Google once got exploited due to security breach through their DNS protection mechanism, all because one internal employee clicked a malicious link. The worst part is, in many case DNS exploit is actually noticed much later giving the exploiter major scope for stealing confidential data. In the changing world which is getting ever more dependent on the Internet for various activities, it is of utmost importance that organizations take security seriously. DNS Firewall adoption is the right step towards guaranteeing higher protection.
