Why DNS Protection is an Absolute Necessity?

DNS (Domain Name System) is one of the most fundamental things which constitute the whole operations of internet. In simple words, Domain Name System is used each and every time an individual visits a website, initiates an e-mail, receives and e-main or chat with friends over internet messaging services. In shorts, no matter whatever you do over internet, DNS pays a vital role from the initiation of the action, to the execution of the action, to the ultimate completion.

Before I start on why DNS protection is necessary, let me give you an idea on what could happen if the DNS is not protected. Back in 2008, Dan Kaminsky discovered a very serious loophole in DNS system. With this DNS vulnerability, any hacker can redirect a network query to the servers of his choice.

This discovery of Dan Kaminsky led to the concept of DNS Cache Poisoning.

What is Cache Poisoning?

Assuming an attacker has complete knowledge of how DNS works, Cache poisioning can be a piece of cake for the attacker. In this, the attacked somehow figures out how to infuse sham information into a nameserver’s cache.

This infusion then leads to the infection of local client’s devices that are clueless about this whole attack. When the devices of local clients get infected, the nameserver treats the bogus packet of information as a genuine one and hence, the DNS breaks down while leaking all the personal and private data to the attacker.

Do not get Cache Poisoning confused as traditional Phishing attacks.

How Cache Poisoning is different from traditional Phishing techniques?

It is true that the target result of both the cache poisoning and phishing is the same thing: Making the person unsuspected about the bogus site and treat it as the real URL but they are not the same.

In Phishing, a similar looking webpage is developed by notorious attackers with HTML and CSS skills to fool the user. In this technique, no technical knowledge of DNS functionality is required. Also, if the end user is a bit skilled in coding, he can easily identify the phishing attack just by merely comparing the HTML source codes of real and duplicate pages.

Whereas, in DNS Cache Poisoning, the infrastructure of DNS gets compromised. It takes the advantage of the natural fundamental working capability of DNS. In this, the attacker re-routs the real hostnames to the attacker’s servers. Also, this technique requires professional knowledge of DNS infrastructure and the attack cannot be identified by comparing any kind of source codes.

Why DNS Protection is Necessary?

By now, you must have known how venerable DNS is. Now let me tell you why DNS protection is an absolute necessity.

The whole networking communication of any corporate office revolves around the DNS infrastructure. It shouldn’t come as a surprise if a competitor wants to take your server down.

What will be their first and foremost approach?

To take down the most venerable part of your system.

That is an unprotected DNS for you!

If you don’t want the attacker to take your server down with your private and personal information, get a DNS protection system now!
