DNS Based Protection or WebProtect
As part of our Cyber CEO series, we’re exploring essential tools and strategies to enhance your cyber security. Safeguarding your online presence is more important than ever. One effective method is DNS-based protection, also known as WebProtect. Let’s delve into what DNS is, how DNS-based protection works, and the benefits it offers. By understanding these concepts, you can ensure a more secure and efficient Internet experience for your business, whether your team is working from the office, home, or on the go.
Understanding DNS-Based Protection
What is DNS?
DNS stands for Domain Name System, and it’s essentially the phone book for the Internet. Just as you use a phone book to find someone’s number, DNS is used to find the IP address of a website.
For example, when you want to visit google.com, your computer asks the DNS “phone book” what the IP address for Google is. The DNS responds with an IP address like 172.217.167.78. This system ensures you don’t have to remember complex numerical addresses for every website you visit.
How DNS-Based Protection Works
DNS-based protection uses this system to enhance your online security. Whenever your computer accesses the Internet, it checks the DNS to find the IP address of the site you want to visit. By controlling this “phone book,” DNS-based protection can block access to harmful sites. For instance, if a site is known for phishing or illegal activities, it can be blocked automatically.
Benefits of DNS-Based Protection
This protection method is efficient and fast because it doesn’t require scanning. It simply ensures you’re using a secure DNS, often provided by your cyber security partner, rather than the one from your Internet provider. This setup is especially useful for remote work, as it works regardless of your location, whether you’re at home, in an Internet cafe, or in the office.
Moreover, DNS-based protection can be implemented on a firewall level, which means it can also cover BYOD (Bring Your Own Device) and contractor devices. It provides a consistent layer of protection across all environments.
Another benefit is the ability to track Internet activity, which can offer insights into employee productivity. Some solutions are developing productivity reports based on this data, providing valuable information on how Internet resources are being used within your organisation.
Antivirus and DNS-based protection, such as those offered by Webroot, can cover about 47% of your security needs. It’s crucial to work with your IT or cybersecurity partner to implement essential controls recommended by the Australian Cyber Security Centre (ACSC), adding another layer of protection. With end-user awareness training and additional measures, you can achieve comprehensive protection for your business.
