IoT Server Availability Considering DDoS-attacks: Analysis of Prevention Methods and Markov Model

The server is an important for storing data, collected during the diagnostics of Smart Business Center (SBC) as a subsystem of Industrial Internet of Things including sensors, network equipment, components for start and storage of monitoring programs and technical diagnostics. The server is exposed most often to various kind of attacks, in particular, aimed at processor, interface system, random access memory. The goal of the paper is analyzing the methods of the SBC server protection from malicious actions, as well as the development and investigation of the Markov model of the server's functioning in the SBC network, taking into account the impact of DDoS-attacks.
