DNS functions as the Internet’s control plane, offering unparalleled insights into applications, devices, and the flow of data in and out of a network. A significant majority, approximately 80%, of malware employs DNS for communication with Command & Control, facilitating activities like DNS data exfiltration/infiltration and phishing attacks via deceptive domains. Response Policy Zones (RPZ) or DNS Firewall is a feature that empowers the implementation of security policies on DNS. It’s noteworthy that most commercial DNS Firewall providers do not permit users to generate their own data feeds.

A DNS server, similar to ioc2rpz, automatically generates, maintains, and disseminates DNS Firewall data feeds from various sources, including local files, databases, and remote locations like HTTP, FTP, and RPZ. This capability streamlines integration with Threat Intelligence providers and Threat Intelligence Platforms. The resulting data feeds can be distributed to a wide array of open-source and commercial DNS servers that support DNS Firewall/RPZ (Response Policy Zones), such as ISC BIND, PowerDNS, Infoblox, BlueCat, Efficient IP, and more. By utilizing a solution like this, you gain the ability to create custom data feeds, implement actions, and proactively prevent undesired communications from occurring.
