Chapter 5 - Security for Industrial Automation

Abstract

This chapter discusses the security for industrial automation. One of the very largest problems facing the automation professional is that the control systems in plants and the SCADA systems that tie together decentralized facilities, such as power, oil, and gas pipelines and water distribution and wastewater collection systems, are designed to be open, robust, and easily operated and repaired, but not necessarily secure. An analysis of the security needs of industrial automation is briefly explained; industrial automation systems (or industrial control systems, abbreviated ICS) are an integral part of the industrial infrastructure supporting the nation’s livelihood and economy. There are numerous industrial recommendations that are provided in this chapter, such as developing a clear understanding of ICS cyber security; developing a clear understanding of the associated impacts on system reliability and safety on the part of industry, government, and private citizens; defining cyber threats in the broadest possible terms, including intentional, unintentional, natural, and other electronic threats, such as electromagnetic pulse (EMP) and electronic warfare against wireless devices; and developing security technologies and best practices for field devices based on actual and expected ICS cyber incidents.
