This session will describe the basics and purpose of the Manufacturer Usage Description (MUD) protocol, a proposed modification to the DHCP standard and currently under review by IETF. Many IP-enabled devices, such as IoT devices, cannot or will not provide their own protection. So rather than expect that manufacturers will keep up with all of their devices and provide solid security, MUD spreads the security load. The result is that the manufacturers provide their expertise on what’s appropriate behavior for their devices and network security vendors can ingest that info to create network policy, primarily to prevent lateral movement within the network.
