Security of Cyber-Physical Monitoring and Warning Systems for Natural and Technological Threats

Abstract

This work describes the use of cyber-physical architectures for the construction of regional environmental monitoring and alert system for residents to the natural and technological threats. Regional systems are structures covering an area of several km2. The work focused on ensuring the security of collected and processed information as well as the continuity of system operation. The base tool to improve its parameters is the use typical solution for cyber-physical systems, including component of Internet of Things. Nationwide, environmental monitoring in most countries is still based on IT solutions from the early 1980s. In the case of slow-changing global threats covering large parts of country, this solution works well. However, for dynamically changing regional threats, using them for early preparation of accurate warnings is impossible. As a solution for such problem, we are using the data that comes from weather stations owned by the residents of the monitored area, that was designed using Internet of Things technology. This approach creates new, unprecedented threats to information security and system continuity. In addition to threats resulting from the use of the Internet of Things, there are new, resulting from the properties of algorithms for threats forecasting, which require, among others input dataflow continuity. In work the functional organization of environmental monitoring system and their architecture are presented. On their basis the methods and means of counteracting security and accessibility threats are evaluated. This work describes also the implementation of environmental monitoring system in a town adjacent to a larger agglomeration.
