DNS Firewall is a type of firewall that relies on Domain Name System (DNS) technology to protect the network from unauthorized access. DNS Firewall uses a DNS server to lookup the IP addresses of computers on the network and blocks access to any computers that are not registered in the firewall’s whitelist.
DNS Firewall is a valuable tool for organizations that need to protect their network from unauthorized access. By using a DNS server to lookup the IP addresses of computers on the network, DNS Firewall can block access to any computers that are not registered in the firewall’s whitelist.
This prevents hackers from accessing sensitive data or attacking network servers.
While DNS Firewall is a valuable tool, it should not be used as a replacement for traditional security measures. DNS Firewall is not a full security solution and should be used in conjunction with other security measures, such as antivirus software and intrusion detection systems.
