A DNS firewall is a software that ensures the DNS is secure. It prevents system and enterprise employee connections to the already known and established malicious internet locations and provides instantaneous feedback to security teams about potential malicious software like APTs and botnets on the network. All that is needed to create a DNS firewall is a list of malicious websites, hostnames, or domains, which can easily be added to the DNS configuration to block the locations automatically. By using protected DNS gateway, a business can ascertain its IT systems and employees are not routed to destinations that deter communications, private customer data, proprietary information, and more.
The other advantage of the dns firewall is that you have all you need regarding the DNS resolver structure. This means there is no hardware installation, software updates, network configuration projects, or other projects that can jeopardize system security. In fact, the firewall can be put to work in a matter of days through vendor solutions, with few manuscripts, some reliable information sources, or talk to a DNS administrator. The trick is how timely, comprehensive, and accurate your information is and how indisputable you are with the choice of implementation. For most businesses, the most preferred choice is the tested vendor solution, as they provide information threat forwarded over secure DNS to your network rather than flawlessly.
Why the DNS Firewall is Essential in Network Security
DNS firewall prevents systems from getting into contact with malicious and harmful resources over the internet. The firewall delivers a constant update that contains domains and IP addresses used by unwanted traffic from your network, and potential threat actors out of the network so that traffic can be monitored, blocked, or redirected to safer locations.
• A DNS firewall prevents any possible communication with emerging threats and known threat actors based in a popular threat intellect platform.
• The firewall blocks out of bounds communication to selected threat topographical locations.
• The firewall blocks activities including ransomware, phishing, malvertising, typo-squats, botnets, and other malware types.
• A DNS provides advanced reporting into blocked DNS query, and identifies the affected computers, allowing for efficient and accurate remediation.
• It helps users manage and build up security policies through the identification of the threat types and add to the list of identified domains.
