Developments in technology have provided better means of protection against malware. Attackers, nevertheless, are always busy trying to match it in new technological innovation with their own sophistication. Therefore, there is need for a strong DNS firewall that will not only offer the required defense but also other qualities in the quest to satisfy all the requirements of smooth and safe running of your business.
Powerful Centralized Management
Having to log into countless firewalls in order to view activity or make changes is not only tiresome and time consuming, but also costly. Therefore, you should employ a system capable of central management and allows your internet security team to act quickly in the event of signs of an attack. Additionally, it should allow automation of tasks, use of shortcuts and reusing of elements, thus enabling high efficiency with little effort.
In this age of technological innovations, downtime during maintenance of networks should be a thing of the past. To ensure there is no interruption during updating and maintenance of your system, you can use active-active clustering. It allows flexibility and no-by-node upgrading without having to experience service breaks by utilizing different versions of hardware and software when conducting maintenance.
If your business organization is made up of branches distributed in far and apart locations, you should go for DNS firewall that allows cloud installation and configuration. In addition, anyone at the remote location should easily be able to begin the process of activating it by a single act of plugging in power while the rest of the connection activity is handled remotely. This results into a great saving on time and costs that would have been incurred during travelling. The firewall should also offer automation options for remote locations as well as the ability for centralized remote operations.
Various other requirements for an efficient DNS firewall might seem obvious but they are of utmost importance. These include Deep Packet Inspection (DPI) capabilities that allow thorough inspection of every packet with the aim of picking out the malformed ones as well as detecting attacks, errors and other forms of malware. With the current sophistication of internet attacks, the firewall should also provide protection against Advanced Evasion Techniques (AET) by getting rid of any complication that may prevent thorough examination of traffic across various layers and protocols.
