Why Do I Need A DNS? Protect Your Devices As You Protect Your Home!

My previous article discussed the various levels of consumer malware protection — from an antivirus solution to next-generation antivirus, and then to full endpoint protection. I showed that a solid EDR can act as a fortified wall and prevent most threats.

Protecting your devices works in the same way as you protect your home by utilizing different layers of protection. Protection is built in layers, with each one forming an integral part of the fortified structure. Walls, gates, doors, locks, and cameras combine to give you the best protection.

So let’s ask ourselves a question: When it comes to your home — how do you control who can enter and how do you know who to trust? If I had the best hi-tech wall protecting my home, would I leave my gate wide open?

The gate is what allows you to filter who enters your boundary. Likewise, when it comes to our cybersecurity, we need to be able to filter who or what is entering our personal zone. For this, we can utilize a DNS (Domain Name System) server.

What exactly is a DNS?

DNS is the naming system used to classify services, computers, URL addresses and other assets reached through Internet Protocol (IP) networks. It effectively serves as the “phonebook to the Internet.”

A DNS works by translating a website’s domain name into an IP address in order to make it readable for a computer, which will then load a webpage. This makes life much simpler for a user — all we need to do is type a website address into the search bar, instead of trying to remember more complicated IP addresses. (If you want to learn more about how DNS works, check out this great video).

Additionally, we can add functionalities on top of the DNS itself in order to filter harmful content, stop suspicious trackers, and block inappropriate web pages, effectively protecting our online navigation from phishing and other cyber threats.

If DNS itself is the phonebook, think of DNS filtering as a caller ID system that can enable spam call blocking.

How do I choose which DNS to use?

Many devices have a default DNS, but ultimately, you are better off having the capability to choose your own. Different DNS servers have different levels of speed and security so having autonomy over which one you choose is important.

  • Tracking: You may not realize it but everyone is trying to watch your online activity — from online social media to the companies behind shopping websites. The trackers per user these days can be in the hundreds. Trackers are used for two main reasons:
    * Analytics: To learn how you interact and behave at a specific website.
    * Advertising: To apply better targeting with online ads that will feel relevant to the user.

    Trackers may collect browsing habits and personal information like your IP address, name, gender, and any other details you may have shared with a website. Understandably, this doesn’t sit well with most users! But with a DNS, you can block affiliate and tracking domains in order to protect your privacy.
  • Speed: Using the right DNS can actually increase the speed at which your web pages load. This is because your device is not waiting for heavy, intrusive ads to load. The end result is a much faster, cleaner internet browsing experience.
  • Filtering: When it comes to protecting your family, setting up customized content filtering can be a great way to block indecent, inappropriate and malicious content from being accessed — or from having access to your loved ones! A good DNS system will block ads and filter URLs containing malware that could potentially harm your device or compromise your accounts.

So it’s well worth taking your time to choose one of the DNS options available to you online. For example, you can easily compare DNS performance and analytics on sites such as DNSperf.
