Industrial Control Systems (ICS) have experienced an exponential increase in cyberattacksover the last decade. The industry has responded to cybersecurity threats by creatingstandards to assist end users and equipment vendors through the process of securing industrial control systems.
There are a number of key standards available in the market today. IEC 62443 has been developed by both the ISA99 and IEC committees to improve the safety, availability, integrity, and confidentiality of components or systems used in industrial automation and control. The IEC 62443 series of standards can be utilized across industrial control segments and has been approved by many countries. IEC 62443 is evolving to become a key standard in the industry, and Schneider Electric is building its cybersecurity strategy around the standard.
This document is designed to introduce concepts to an individual with limited exposure to cybersecurity in industrial control systems, providing implementation guidance using practical examples.
