One of the fastest developing information technologies, the Internet of Things (IoT) facilitates integration of diverse devices and objects. The IoT technology is based on the strengths of the Internet, particularly on the ability to establish networks of cooperating devices used on a mass scale. More and more numerous devices are connected to the Internet which also serves to monitor their condition and work. This shows the future potential utilization of the Internet for various aspects of the management of economic processes and for complex systems of assuring the security and continuity of functioning of individual subjects and of the entire state. Farther development of this technology may, in the future, become the basis of the development of other technologies and of the implementation of diverse network models in economic and organizational processes in order to improve their effectiveness. This effectiveness can be directly related to the collection of very large amounts of data and to the multifaceted data exploration online (Big Data systems). Increasingly essential are therefore the issues of data explosion, of data processing security and of the security of the whole technology.
