The paper considers the tasks and solutions for availability assessing and securing the Internet of Things (IoT), in particular, the Smart Business Cen- ter (SBC) with wired communication networks. The goal of this paper is to de- velop and research of SBC availability models, taking into account the changes in power consumption modes in operating systems, denial-of-services (DDoS) attacks, patching for firewalls depending on the presence of software vulnera- bilities, considering reliability of system components such as a server and a router. Comparison of several models of the IoT system availability has been made and recommendations have been formulated regarding the policy of patching.
