Technology is ever-prevalent in today’s world. Even more so, small and large businesses alike rely on technology, internet, and a variety of software to get their work done. Taken granted by most people, specifically the internet, we often overlook at exactly how intricate the internet really is. Most of us don’t understand that this complexity is what causes security issues, and is exactly what cyber criminals like to exploit and target.
What is DNS?
DNS, also known as Domain Name Service, is the internet’s version of an old-school phonebook. In it, it keeps track of domain names (website addresses and URLs) and their corresponding IP addresses (a unique string of numbers that is assigned to any device that is connected to the Internet). When you visit, let’s say, ‘www,google.com’, your internet provider’s DNS will find the IP address associated with that web address and direct you to their webpage. Simply put, the DNS is like a GPS that helps direct you where you want to go. And all of your internet traffic goes through it.
Why is DNS Important?
If you didn’t have a phonebook, how would you be able to keep track of all the phone numbers of your friends, family, and services that you use? You won’t be able to, unless you have an unnaturally good memory. But aside from that, you would really rely on your phonebook to provide you with the phone numbers of people you frequently want to contact, and trust that the numbers are correct.
Now, you can imagine why cyber criminals would want to target your DNS. If they are able to redirect your internet traffic to websites full of malware, they are able to cause you all sorts of problems. One such major problem is known as Cryptolocker.
What is Cryptolocker?
In 2013, cyber security agencies recognized a new type of malware called Cryptolocker. Simply put, once Cryptolocker infected a computer or device, it was quickly able to contact a control server and get an “encryption key”, and subsequently encrypt (lock) files across the device’s storage, causing most of the user’s files to become inaccessible, unless of course they pay a ransom fee (thousands of dollars) to get the unlock key.
How can this be Prevented?
There are many ways to prevent these type of malware attacks and issues. For example, running frequent malware scans on your device is a good way to check and quarantine any suspected or corrupted files. However, protection needs to go beyond that. This is where DNS protection comes in.
What is DNS Protection and Webroot?
DNS Protection is the procedure of using a specific DNS server that has the functionality to scan and detect malicious websites before directing you to them. Using Webroot DNS Protection, Endless Technology Solution’s security experts know exactly what to look for and how to configure Webroot’s DNS system so it protects its clients from all types of malware, including Cryptolocker. In addition, if by some nature a device gets affected by malware, Webroot DNS Protection immediately quarantines the file and prevents it from successfully communicating to it’s home server, which is necessary for it to work.
