Numerous IoT applications, like building automation or process control ofindustrial sites, exist today. These applications inherently have a strongconnection to the physical world. Hence, IT security threats cannot only causeproblems like data leaks but also safety issues which might harm people.Attacks on IT systems are not only performed by outside attackers but alsoinsiders like administrators. For this reason, we present ongoing work on aconfiguration management system (CMS) that provides control overadministrators, restrains their rights, and enforces separation of concerns. Wereach this goal by conducting a configuration management process that requiresmulti-party authorization for critical configurations to achieve Byzantinefault tolerance against attacks and faults by administrators. Only after aconfiguration has been authorized by multiple experts, it is applied to thetargeted devices. For the whole configuration management process, our CMSguarantees accountability and traceability. Lastly, our system istamper-resistant as we leverage Hyperledger Fabric, which provides adistributed execution environment for our CMS and a blockchain-baseddistributed ledger that we use to store the configurations. A beneficial sideeffect of this approach is that our CMS is also suitable to manageconfigurations for infrastructure shared across different organizations that donot need to trust each other.
