“…Finally, some other works proposed different types of gateways for SB. In [69], a gateway relying mainly on XML exchanges over HTTPS is proposed to improve authentication. In this project a set of redundant authentication gateways are developed that manage the access of users to end points, which can be used to enforce a security policy.…”

Smart Buildings are networks of connected devices and software in charge of automatically managing and controlling several building functions such as HVAC, fire alarms, lighting, shading and more. These systems evolved from mostly electronic and mechanical elements to complex systems relying on IT and wireless technologies and networks. This exposes smart buildings to new risks and threats that need to be enumerated and addressed. Research efforts have been done in several areas related to security in smart buildings but a clear overview of the research field is missing. In this paper, we present the results of a systematic literature review that provides a thorough understanding of the state of the art in research on the security of smart buildings. We found that the field of smart buildings security is growing significantly in complexity due to the many protocols introduced recently and that the research community is already studying. We also found an important lack of empirical evaluations, though evaluations on testbeds and real systems seems to be growing. Finally, we found an almost complete lack of consideration of non-technical aspects, such as social, organisational, and human factors, which are crucial in this type of systems, where ownership and liability is not always clear.

We propose, in this paper, a general modelling technique of an autonomic multi-tier system implementing selfhealing and self-protection properties. The modelling is based on stochastic Petri nets (SPN). Our objective is to forecast the most appropriate configuration for a multi-tier system and ensure the effectiveness of the autonomic manager. We consider in our modelling an autonomic diagnostic and recovery, with fault tolerance solutions. The diagnostic is directed by the workload intensity, possible attacks and failure frequency. Finally, we illustrate the effectiveness of our modelling through a set of experimental analysis results.

Autonomic systems providing self-healing and selfprotection capabilities have been proposed to efficiently automate rectification of system faults and recovery from malicious attacks. In fact, it becomes more and more difficult, labor-intensive, expensive and error-prone to conduct such recoveries. Self-healing techniques and security mechanisms are resource intensive and may affect system performances and even its full operability. Therefore, balancing security and performance in these systems is needed and self-management strategies should guarantee a minimal level of functionality.In our work, we are interested to provide methodologies and tools to predict the behaviour and efficiency of autonomic strategies relating self-healing and self-protection, before applying some healing solutions. The idea is to forecast the most appropriate configuration and ensure the effectiveness of the autonomic manager after application of a solution. So, we propose, in this paper, a general modelling methodology of an autonomic system implementing self-healing and protection, based on stochastic Petri nets. We consider in our modelling an autonomic diagnostic and recovery of fault-tolerant multi-tier systems, directed by the workload intensity, possible attacks and failure frequencies.We illustrate the effectiveness of our approach through a set of experimental analysis results.
