Smart Home Systems (SHSs) represent one of the most prevailing Internet of Things (IoT) applications. While IoT-based SHSs can be user-driven or automatically operated, their unauthorized or unexpected operation brings new security and safety concerns that did not exist in legacy homes. This paper provides a review of the state-of-the-art approaches for securing the operation of SHSs. We first present security threats that may lead to unauthorized/unexpected operation of an SHS for both types of operation. Then, we review existing security approaches for each type of operation. Finally, we draw some conclusions and raise open research issues based on this review.
