Nowadays DDoS attacks using IoT devices are frequent and extensive. Given that IoT network instances are distributed and deployed over conventional Internet gear, DDoS countermeasures in IoT need to be fully distributed and coordinated all over the components that form each IoT instance. This paper presents a designed and prototyped distributed host-based intrusion detection systems (HIDS) that aims to protect the components of IoT network backbones, comprising conventional switches and routers. In our design, a set of the proposed HIDS executes conventional security verifications, like default username and password, known attacks signatures, monitoring the usage of resources, processes, ports and open connections, while also interacting with a Controller of the HIDS set to allow the coordination of intrusion detection actions relative to DDoS attacks all over the IoT instance. The designed distributed HIDS is evaluated in a controlled environment that, although being a local and isolated network, realistically represents IoT network instances.
