Practical Industrial Control System (ICS) Cybersecurity: IT and OT Have Converged – Discover and Defend Your Assets
This article will explore the issues that arise with the blending of IT and OT into combined cyber-physical systems where risks must be identified and managed. Specifically, it will help you address these questions:
– Why are digital asset inventories critical for IT/OT security risk management?
– How does knowledge about risks and vulnerabilities to IT/OT systems lead to better risk management?
– Can applying even a few of Center for Internet Security (CIS) Controls make a marked difference in the security posture of today’s control systems?
Equipped with answers to these questions, industrial and information system administrators can make more informed decisions about how to build stronger cybersecurity programs to protect IT/OT systems.
