By Anderson Harford 2016-04-13 00:00:00

DNS services are essential for managing the relationship between users and network administrators. But in order to do so, people must know what are the threats that need to be managed and how do you protect yourself from these threats. What follows is a list of dangers that DNS services manage and the possible solutions for protecting a DNS.

So what are the threats to a DNS?

  1. UNWANTED CONTENT: DNS services filter the content that is unwanted and can do this without needing to install software on devices and computers. This filtering is essential for maintaining the integrity of the content and ensuring that users are finding more of what they are looking for.
  2. PHISHING AND MALWARE BLOCKING: This is related to the above filtering, but beyond maintaining the integrity of your content, blocking malware and phishing protects the site and its users from viruses, scams, and the limitless creativity of malignant internet pirates who prey on unsuspecting DNS’s.
  3. ADVERTISEMENT BLOCKING: Blocking advertisements is a huge priority for many DNS services. Yes, it is another type of content filtering, but it is important in order to ensure that users are finding what they are looking for and not being led astray. And on the other side of the coin, that administrators are delivering the message and creating the experience they intend.
  4. Botnet Defense: Botnets are the zombies of the internet. They are a network of private computers that have been hijacked with malicious software and controlled as a group unbeknownst to the owners’. These Botnets are used to do such things as send spam messages.
  5. URL CORRECTION: To truly understand this threat you can do a little experiment and type Goggle when you meant to type Google and see where you end up: probably not where you intended, however, if you type Gogle instead of Google you will appreciate the importance of typo correction.

When looking for a DNS service there are some basic features or services you should look for in order to protect your DNS from the above threats.

  1. Choose DNS providers that have preconfigured or automatic content filtering. This alone will solve three of the above five threats.
  2. Look for a DNS service that will allow you to have a customization account so you can customize the level of protection and messages that pop up whenever a site is blocked.
  3. Because domain resolution is important for determining the speed and reliability of your web browsing, be sure that you can run speed tests on the DNS servers. This not only allows you to test the compatibility of your site but also, as a consumer allows you to compare performances at your location.

DNS services are like an evolving thing. As the threats evolve so do the features to defend against them. It is important to keep up with what is out there so that your DNS is protected or use the services of a specialist like BlueCat. Nowadays, you can expect a DNS service to predict attacks before they happen, remove blind spots, and to expand threat protection beyond the perimeter.
