Security in building automation systems - a first analysis

The purpose of building automation systems is to support all house functions, such as controlling lighting, air conditioning, heating, shading, access, and hence, increase comfort, save energy and provide easier administration. Those systems are highly complex and ubiquitous as they have interfaces to many other networks and systems in a building. This increases the risk that attackers use security gaps to affect the entire infrastructure. In this paper we report about a security analysis of building automation systems.
