Graph-based IoT microservice security

The Internet of Things (IoT) can be considered as Service Oriented Architecture (SOA) of Microservices ($$S). The μSs inherently process data that affects the privacy, safety, and security of its users. IoT service security is a key challenge. Most state of the art providing IoT system security is policy based. We showcase a graph-based access control that runs as module on IoT nodes, or in the network. Our solution intercepts and firewalls inter-service communication. It automatically creates a model of legitimate communication relationships. The model is interactively updated via a simple-to-understand interface. Our solution adds inevitable IoT security to existing IoT systems.
