What is DNS?


Invented by Paul Mockapetris in 1983, the Domain Name System (DNS) is a system used by computers to convert the domain names that humans use (ex. www.AVAREN.com), into the IP addresses that our devices use to communicate with one another (ex. For example, when you type a domain name into your browser’s search bar, the device will perform a DNS lookup to determine the IP address associated with that location.

Even though from our (human) perspective it may look like our device is communicating with the domain name that we typed in,  our device is actually communicating with the domain’s IP address. So you might think of DNS as a kind of telephone book/directory for internet resources. Our computers (and other devices) might make hundreds of these DNS lookup requests per day in order to facilitate the routing of network traffic to requested resources.

What is DNS Security?

DNS security takes DNS lookup functionality to a new level by integrating additional security features into the process. Because the DNS lookup process is typically an intermediary between our computers and external domains, blacklists of known disreputable external domains can be added to the DNS lookup process in order to prevent our devices from getting to these bad neighborhoods. For example, if a domain has been identified by IT security workers as containing or hosting malicious code; an entry can be added to the DNS lookup system to prevent devices from accessing this remote resource. Thus, injecting additional security checks into the DNS lookup process can help to dramatically cut down on virus and malware infections within our computing environments.

Once aware that such systems exist to enable security at the DNS layer, would it not make sense to employ this additional security layer within your enterprise as soon as possible? Call AVAREN today and let us begin working to transform the security profile of your computing infrastructure.

Additional Benefits of DNS Security


If the anti-malware/virus benefits of DNS security weren’t compelling enough; there are numerous other reasons why a business manager would wish to implement a DNS security layer. These include:

Uncontrolled internet access can be a tremendous liability for a business. With a DNS security service a business owner can easily blacklist non-productive or non-work related web sites such as social media websites, pornography, and other time wasters. As many as 80 different URL categories can be turned on to prevent employee usage of time wasting web sites.

Multiple different policies for DNS security can be applied at the user, group, or IP level; ensuring maximum organizational flexibility. This capability allows us to configure different levels of internet access based upon departmental or other business groupings. An example of this flexibility would include actions like: blocking Facebook company wide with the exception of the Marketing Department.

A DNS security application can provide transparency into employee internet utilization; and typically includes full reporting capability (by employee) for day/week/month, etc. Configuring a DNS security application within your business is the fastest and easiest way for business managers to obtain these types of insights into employee internet usage statistics.

While configuration changes to existing are required for implementation; DNS security (and its benefits such as web usage tracking) can typically be implemented without the use of additional hardware. Other than DNS Security; there is no solution on the market that can so dramatically and inexpensively impact the cyber-security profile of a business operation.

DNS security can block as much as 90% of web-based malware at the URL level; so these threats never make it back to your network. A thwarted malware infection is one your team does not have to recover from or clean up. We have recognized a notable change in the number of client infections immediately following implementing DNS security at client environments.

A small software client can be deployed for laptop (or other remote workers) to force DNS security compliance when users are outside the office. Once installed, the internet is effectively secured for the end-user in question, regardless of their physical location. Thus, DNS security helps us cut down on client infections even when the client is located outside the office.
