With the growing number of IoT (Internet of Things) devices and their particular characteristics compared to traditional systems, incumbent security mechanisms need to be advanced for secure and resilient IoT operation in current ICT systems. One particular standard, which tries to improve IoT security in that regard, is the Manufacturer Usage Description (MUD) by IETF. In this paper, as our main focus is to highlight the security gains of using MUD, we first discuss the critical threats to IoT devices based on available research. In the second step, we analyze the MUD technology to delineate where MUD is beneficial (or not) to address these security issues.

Softwarized services in converged networks are evolving from monolithic applications to distributed architectures, often comprising numerous microservices. At the same time, with the massive proliferation of IoT devices, much more complexity and diversity are added to such critical infrastructures. In that regard, Root Cause Analysis (RCA) is an important part of a running distributed service ecosystem to keep the applications available and manageable by nding the root causes of errors and malfunctions. This paper provides a topology graph based anomaly detection and RCA solution for the microservice architecture in edge-to-cloud environments entailing microservices in combination with IoT.
