A Domain Name System (DNS) is another one of those systems that get bandied around together with ‘best cybersecurity’, without many people knowing what it actually does or why it’s important. Let’s delve into the what, the why and the how – and get you up to speed with what DNS is all about!
What exactly is a DNS?
Often referred to as ‘the phonebook of the internet’, the purpose of a DNS server is to match the domain names you enter into applications like web browsers with their associated Internet Protocol (IP) address. Let’s take the web browser as an example:
- You enter a domain name into your browser
- Your computer contacts the listed DNS servers
- The servers look up the IP address for that domain name
- Your computer then knows which IP address to send your browsing request to
So, you need a DNS to surf the web. But a DNS can also provide crucial services and functions for users, for the most part by protecting your privacy and use of personal data.
Advertisements can be pretty annoying when you are trying to browse the internet, as well as sometimes offering inappropriate viewing. Ads can sometimes also slow down your internet speed, as web pages become much heavier to load. A DNS can block ads for a cleaner, easier, and faster online experience.
Did you know that operating systems are able to collect endless data about you, your interests and your online browsing activity? This can affect your privacy and your digital footprint. A DNS will be able to block data trackers so that your activities aren’t under constant scrutiny, preventing hackers or malicious software from monitoring activity, recording actions, or attacking assets.
A DNS filter ensures a safe browsing experience, blocking all unwanted advertisements and suspicious URLs. With DNS applications such as RAV Safer Web, you can customize which websites and material you or your family can access – and block those domains deemed safe or inappropriate.
If you or someone else tries to access a website that falls under a category you have blocked, you won’t be redirected there. This provides a much more child-friendly online environment, enabling safer internet searching without the worry your child may access age-inappropriate sites.
DNS filtering can go even further, offering protection against some of the latest cyber threats such as malware, cryptojacking, and phishing scams, as you’ll be protected from having access to sites and links where these threats occur – and they can be blocked from reaching you!
It’s well worth choosing a DNS that combines all elements and functions. With Safer Web, you can upgrade your user experience to the Premium version, offering even more filtering and blocking options. For more information on Safer Web, click here.
