How To Protect Your Network From BYOD Malware Infections With The Help Of A DNS Firewall?

7 min read

Malware is like that uninvited guest who is a big time party spoiler. You never know which device may bring infectious malware to your computer and cause a complete breakdown. The most affected computers are usually those which work under a BYOD (Bring Your Own Device) environment. In big firms, the employees prefer using their own devices the way they want, as the limited choice in the use of devices and tools tend to choke them. Using their own preferred devices makes their work comfortable and efficient. This system, however, poses a big threat to the IT companies as the use of personal devices in working environments may cause many infections to leak into the systems. With these malware attacks taking place frequently, you might have to think twice before allowing BYOD to function. Wait! Ever heard of a DNS Firewall? Obviously, you would have! A DNS (Domain Name System) firewall doesn’t only prevent a network from online threats, but eliminates BYOD malware infections too!

How Does A DNS Firewall Work?

The network can be protected from the malware threats by just getting your local DNS settings changed. DNS firewalls usually come with a cloud-based service that helps protect the systems from harmful threats. Prevention of Botnets and phishing attacks can be carried out with comfort if you have a DNS firewall with you. The network is freed from malware by a complete blockage of unwanted sites and malicious software from entering the same.

A DNS firewall comes with an easy-to-implement setup, which once installed, keeps an eye on all activities going on in the network. If any access to an unwanted content is made, various alerts are generated by the firewall to inform the user about the breach of security. The throughout navigation of a network is carried out frequently for its close analysis. One big thing is, that the installation of individual clients is not mandatory on each device.

If you didn’t get it, let’s try to understand by the following example:

Suppose an employee uses his/her own device while working on an organization’s network. If the network is protected by a DNS firewall, it causes completed blockage to the access of any content that is unwanted or prohibited.

Since the device is employees’ personal belonging, it can be used by the employee in any other network. In this case, there is a great chance of the device being infected by malicious content while being used on another network.

Now, when the employee comes back to his/her working place and connects the BYOD with the same network once again, the infections in the form of Botnets attempt to access its command and control point.

Since the network is already protected by a DNS firewall, it generates alerts to make the systems aware of the malware. In this way, the issue can be resolved by the employees themselves.

With many new technologies showing immense growth in the market, the chances of our systems getting infected would increase too. Futuristic tech equipment such as IOT and other such devices would reach out to a huge population in the coming days, which means more and more devices would be connected to our networks. The firms would not be able to hold back BYOD just for that one reason that it might cause an infection. If you want growth, you would have to be tech-savvy. Don’t worry, just try a DNS firewall. It may help your cause.
