DNS Security: Things You’d Want To Avoid

If you don’t know it then let me tell you that The Domain Name System (DNS) is penetrable. Yes, you heard it right. No matter how overlooked this issue may be, the truth is the DNS is under constant attacks from a variety of sources.

In this blog, we’ll discuss different kinds of DNS attacks which are happening right now in the networking world. In addition to this, I’ll also try to write respective ways by which the threats can be neutralized. So, here we go.

Typosquatting

It is a very common practice of getting into victim’s DNS settings. Typosquatting is a way to create a proxy domain name which is very much similar to the victim’s domain name. Suppose you want to visit facebook.com but you mistakenly typed dacebook.com. Now ideally there shouldn’t be such a site but here is why typosquatting got its name. A DNS hacker will make a site and also different variations of a host site. These variations carry different spellings (including possible typos and mistakes) which re-direct the visitor to a risky server. Now this bad server duplicates the login page of original site. User, without an ounce of doubt, puts down the login credentials and unknowingly, the server is now hacked!

Typosquatting is one of the oldest yet effective ways of DNS hacking which has always given sleepless nights to DNS security. (Figuratively ;-))

One of the most prominent ways to protect your brand against Typosquatting is by registering all the possible matching domains along with your main domain. Keep registering the domains which you think can be used against you by typosquatting.

Let’s move to the 2nd most talked about DNS security attack:

Distributed Denial of service (DDoS) attacks

DDoS attacks are famous for their complex designs. Under these kind of attacks, the underlying server infrastructure is targeted. This doesn’t attack to breach the security of your domain but it’ll hold the information from your server side when a user attempts to open your site. This attack enables the hackers to inject a soft virus which takes all the login information, security codes and personal information to the hacker’s servers.

Performing DDoS has been a trend in DNS hacking arena and despite of all the security advancements, somehow these cyber criminals find a loophole and create havoc. The only way by which the attack can be stopped is by updating your DNS security on a regular basis.

Traffic attack is one of the sub-attacks of DDoS where huge amount of network request is sent to the target which floods the system and in-between, genuine requests from clients / visitors get lost.

Updating DNS security with the latest firewall is the optimal remedy for this situation.

Hijacking The Registrar

All the domain names are registered through a registrar who has all the information of your server. Now if an attacker gains control over this registrar, virtually the attacker also has control over your domain system.

In order to avoid this situation, choose the registrar wisely. One who provided added DNS security features can be the one which can protect you from this as well the all the mentioned DNS attacks.
