IETF introduces manufacturer usage descriptions to help secure IoT devices

Share on FacebookTweet

The Internet Engineering Task Force (IETF) has introduced manufacturer usage descriptions (MUD) which provides the basic framework to allow manufacturers to provide policy that can be used to generate IP-based access lists. This feature will detect and possibly prevent Internet of things (IoT) devices to unrestrictedly access the network, but only allow them to connect to the dedicated services. MUD is realised as RFC 8520.
