MUD-CCF – IoT Behaviour-Based Security Certification

Manufacturer Usage Description (MUD), defined by the Internet Engineering Task Force, allows IoT devices to declare their intended network behaviour.

Scalability and Automation

MUD-CCF is particularly vital for the scalability of secure IoT deployments. In enterprise or industrial environments with thousands of devices, manually configuring firewall rules for every asset is impossible.

MUD-CCF allows for "zero-touch" onboarding where a device connects, declares its profile, is verified, and is immediately secured by the network. This automation reduces human error and ensures that security policies are applied consistently across massive fleets of diverse IoT products.

MUD-CCF Certification

The MUD Conformance Certification Framework (MUD-CCF) validates that:

The device behaviour matches its declared MUD profile.
No hidden communications or unsafe traffic exist.

This provides a trust mark for secure-by-design IoT products and enables automated network protection with minimal operational overhead.
