Why DNS Filtering Should Be Part of Every Organization's Cybersecurity Plan
As an IT professional, IT manager, or IT decision-maker, you know just how critical it is to have a strong cybersecurity plan in place. Every day, new threats are emerging, and cyber attackers are becoming more sophisticated. This makes it increasingly difficult to protect your organization from online threats, such as phishing, malware, ransomware, and zero-day attacks. That's why you need to have a plan that includes DNS filtering.
What is DNS Filtering and Why is it Important for Cybersecurity?
The Domain Name System (DNS) is an integral part of the internet. It is responsible for resolving domain names into IP addresses, which allows computers to communicate with each other. DNS filtering is a technique that uses this critical aspect of the internet to protect your organization from malicious domains.
DNS filtering works by examining the DNS queries that are sent from your organization's devices and blocking any that are associated with known malicious domains. This prevents your devices from communicating with domains that are known to host malware, phishing sites, or other harmful content.
By implementing DNS filtering, IT professionals can effectively block malicious domains and protect their organizations against phishing, malware, ransomware, and zero-day attacks.
How Does DNS Filtering Work?
DNS filtering operates at the network layer, before the request even reaches the application layer. This is important because it provides an additional layer of protection, even before the device requests the content from the malicious domain.
Here's how it works:
A device in your organization makes a request to access a website, such as "www.enterprotect.com".
The request is sent to the DNS resolver, which is responsible for resolving domain names into IP addresses.
The DNS resolver checks its database for the IP address associated with "www.enterprotect.com".
If the DNS resolver does not have the IP address in its database, it will send a request to the authoritative DNS server to retrieve it.
The authoritative DNS server returns the IP address for "www.enterprotect.com" to the DNS resolver.
The DNS resolver returns the IP address to the device, which then sends a request to the website.
The DNS filtering solution checks the request against its database of known malicious domains.
If the domain is known to be malicious, the request is blocked, and the device is prevented from communicating with the malicious domain.
The Benefits of Implementing DNS Filtering in Your Organization
There are several benefits to implementing DNS filtering in your organization, including:
Protection against phishing attacks: Phishing attacks are becoming increasingly sophisticated and widespread. By implementing DNS filtering, IT professionals can protect their organizations against these attacks by blocking access to known phishing domains.
Protection against malware: Malware is a major threat to organizations, as it can compromise sensitive information, steal sensitive data, or cause widespread damage to devices and systems. By blocking access to known malicious domains, IT professionals can protect their organizations against malware.
Protection against ransomware: Ransomware is a type of malware that encrypts your organization's files and demands payment in exchange for the decryption key. By implementing DNS filtering, IT professionals can protect their organizations against this type of attack by blocking access to domains associated with ransomware.
Protection against zero-day attacks: DNS filtering can also help organizations protect against zero-day attacks, which are threats that emerge before security patches are available. By blocking access to malicious domains, organizations can reduce the risk of falling victim to these attacks.
How to Implement DNS Filtering
Implementing DNS filtering is a straightforward process that can be done in just a few steps:
Choose a DNS filtering solution: There are several DNS filtering solutions available on the market, so it's important to choose one that meets the specific needs of your organization. Consider factors such as ease of use, cost, and the level of protection offered.
Configure the solution: Once you have chosen a DNS filtering solution, you will need to configure it to meet the needs of your organization. This may involve specifying which domains should be blocked and which should be allowed, and setting up alerts for when potential threats are detected.
Deploy the solution: Once the solution is configured, it can be deployed to your network. This may involve installing software on individual devices or configuring your network's firewall or router to use the solution.
Monitor network activity: Finally, it's important to monitor network activity and adjust the DNS filtering solution as needed. This can help you stay ahead of emerging threats and ensure that your organization's network is always protected.
