DNS filtering solutions are an efficient way to protect your business from cyber-attacks. 

As people worldwide are using internet services, IoT devices, and cloud computing, the attack surface has increased.

In addition, remote work is flourishing, and you don't know how safe the network and devices of your employees and contractors are.

Meanwhile, cyberattackers have become more advanced and are deploying innovative ways to infiltrate networks, systems, and data. Even technologies like firewalls and antivirus software fail before them.

This is where DNS filtering services such as SafeDNS can help provide superior protection to all your networks, data, devices, and remote workforce. 

In this article, we will understand what DNS filtering is and its benefits. 

Let's start!

What Is a DNS?

Domain Name System (DNS) is used to match a domain name such as Geekflare.com to an IP address. 

IP addresses are a long and unique string of numbers and characters that can identify a device in a network. This address such as 192.0.2.1, 2001:db8:0:1:1234:0:567:8:1, etc., can be complex to remember. 

DNS makes this simpler by corresponding a web domain name with its IP address so that users can easily access websites on the internet. 

Instead of memorizing complex IP addresses, it works like a phonebook or a smartphone's contact list. You can store your contact phone numbers in your smartphone and call them with a tap instead of dialing each number manually. 

Once you type a site's domain name in your web browser, your device will create a DNS query. It will send this query to a special web server known as DNS resolver to match the requested domain name to an IP address by checking the cache or querying other DNS servers. 

The DNS server now sends the correct IP address as a response to your device, known as “domain resolving”. Finally, your device can contact the server associated with the IP address. 

This will help initiate the connection, and the requested website's content will load. This might sound lengthy, but all this process takes microseconds so you can access a site quickly. 

What Is DNS Filtering?

DNS filtering refers to a process where DNS is used to block or restrict malicious sites and code to filter out inappropriate or harmful content. It helps secure your data, network, and assets from cyberattackers. 

In addition, DNS filtering allows better access controls in an organization and gives you more comprehensive visibility on who has access to what type of data. 

Today, you can find many software solutions with DNS filtering capabilities. They are known as DNS filtering services or solutions, such as SafeDNS.  

How do DNS filtering services Work?

Every DNS query reaches a specially-configured DNS resolver acting as a filter. If it detects a suspicious domain, it refuses to resolve the query and blocks users from accessing the sites they have requested. 

To decide whether or not a user or domain name looks suspicious, DNS resolvers maintain a blocklist. If a domain is listed in this, the DNS resolver will block the site, and if it is not in the list, the domain name's request will be approved to enable access to the site. 

Domain filtering services this capability, and they can also maintain an allowlist to permit only those domains listed in the allowlist while blocking all others. Enabling a DNS filtering service in your network will assess all the incoming and outgoing internet traffic, allowing only safe traffic to pass by. 

These services filter web traffic between the requested web page and the IP address making the request. It will filter the request based on some categories such as social media, news channels, phishing campaigns, malicious sites, inappropriate sites, etc. Next, it will block the ones looking suspicious or harmful.    

Example: Suppose you have deployed a DNS filtering solution in your organizational network. If any employee clicks on a harmful link received via mail, the request will first go to the DNS resolver using your DNS filtering service instead of going directly to the malicious site. The DNS resolve will block this request if it finds the malicious site on its blocklist, preventing the attack. 

Why Do You Need DNS Filtering?

Individuals and businesses across the globe are facing cybersecurity attacks. By leveraging advanced technologies and network ransomware, intruders can launch malicious campaigns without human intervention. They attempt to breach your organization's security to steal information, hack your accounts, threaten you for money, and whatnot. 

Hence, you must always be prepared to face cyberattacks, which can be of many types:

  • Malware: It may include spyware, worms, ransomware, viruses, trojans, etc. Malware can leverage a weakness to breach security perimeter such as clicking on a harmful link and downloading email attachments. 
  • Phishing attacks: They are common where attackers send a large number of malicious emails to users while disguising themselves as a reliable source. It can be spear-phishing to companies and individuals, whaling to stakeholders and employees, and pharming to any user.  
  • Man-in-the-middle attacks: It occurs when attackers intercept a transaction between two parties to manipulate or steal data. 
  • Denial-of-Service attacks: It occurs by flooding networks, systems, and servers with web traffic to overload bandwidth and resources. It paves the way to other cybersecurity attacks. 
  • SQL injections: It occurs by inserting malicious code in a system or server via SQL language to force the server to give up secured data. 
  • Zero-Day attacks: It's exploiting a vulnerability when a network or system is newly announced and security patches are yet to release.  

Other attacks can be password theft, cross-site scripting, rootkits, IoT attacks, and more. 

Therefore, if you want to safeguard yourself from these deadly cyber attacks, you must always be prepared with effective security tools to ward them off. And DNS filtering is a great way to go about it.
