What is DNS Security Advanced?
Cloud-based DNS security protects your network, monitoring web traffic and stopping connections that threaten your business
Even as technology grows more sophisticated and powerful, security remains a top concern among businesses of every size. Despite advances in cybersecurity solutions, 68% of business leaders report that risks are increasing.1 Between January 2005 and May 2020, authorities recorded 11,762 cybersecurity breaches.2 It’s no surprise then that a full 78% of business leaders report that they lack confidence in their business’s cybersecurity capabilities.3 To combat sophisticated malware, ransomware, and phishing threats, small- and medium-sized businesses need tools that easily integrate with their existing infrastructures without requiring time-consuming management or continuous oversight.
Leaders at small- and medium-sized businesses with limited cybersecurity personnel and resources will appreciate intelligent, proactive platforms that screen for vulnerabilities in near-real time. By examining internet traffic for threats, these solutions can help take pressure off leaders so they can focus on running a successful business. In this article, we’ll take a closer look at one type of cybersecurity solution, Domain Name System security, also known as DNS security.

How DNS works
What is the DNS is and how does it enable your business to access the internet?
The Domain Name System operates like a rolodex or phonebook of the internet. It catalogs all of the domain names, or websites, on the internet and translates them into the Internet Protocol (IP) addresses assigned to devices running on the web.
By coordinating domain names with IP addresses, the DNS makes surfing the internet convenient and virtually effortless. It performs the necessary translation between common website names and the string of numbers compromising unique IP addresses. Without this critical function, internet users would have to recall individual IP addresses, such as 143.24.295.2, instead of the more memorable “amazingbagelexample.com.”
Here is how the DNS look-up process is intended to work:
- Your employee types in a domain name into a browser, generating a DNS query
- A DNS “resolver” chosen by your Internet Service Provider (ISP) receives the query
- The DNS root server forwards the query to your regions DNS root nameserver
- The root nameserver responds by pointing to the appropriate .com, .net, or .org server
- That server responds with the IP address of the requested domain
- The resolver sends a request to the IP address, establishing a connection to the browser
As you can see, the process your browser has to go through to connect to a website is complex. Especially vulnerable is the stage when your business’s network consults the many DNS servers across the world before establishing a connection to an IP address. Between the several information handoffs occurring during a DNS search, a malicious agent can attempt to bypass or confuse the process and gain entry to your network.

Move security into the cloud to help reduce DNS incidents and ease management
Cybersecurity trends reflect broader currents in business technology. For instance, as businesses transfer more and more applications to the cloud, the focus of cybercriminals shifts to infiltrating those resources. Fortunately, cloud-based tools are helping address security challenges by providing powerful protection against threats without requiring businesses to make significant investments in hardware and software.
These cloud-based solutions help protect your employees before they establish a connection with malicious websites. They act as a gatekeeper, monitoring activity between DNS servers and your network. Many have advanced threat intelligence that allows them to keep continual watch for fraudulent requests to and from unauthorized websites, servers, and apps. They block access to suspicious sites before your employees can access them and potentially expose your business and its sensitive information. Even when your staff enters what they believe to be a legitimate URL into a browser, a DNS security platform can authenticate the resolver and root server interactions to help screen the site and determine if it’s safe and credible.
