New attack vectors for building automation and IoT

In the past the security of building automation solely depended on the security of the devices inside or tightly connected to the building. In the last years more devices evolved using some kind of cloud service as a back-end or providers supplying some kind of device to the user. Also, the number of building automation systems connected to the Internet for management, control, and data storage increases every year. These developments cause the appearance of new threats on building automation. As Internet of Thing (IoT) and building automation intertwine more and more these threats are also valid for IoT installations. The paper presents new attack vectors and new threats using the threat model of Meyer et al.[1].
