Measuring Impact of Cybersecurity on the Performance of Industrial Control Systems

Abstract

The National Institute of Standards and Technology (NIST) is developing a cybersecurity testbed for industrial control systems (ICS). The goal of the testbed is to measure the performance of ICS when instrumented with cybersecurity countermeasures in accordance with practices prescribed by national and international standards and guidelines. Examples of such standards and guidelines include the ISA/IEC 62443 Industrial Automation and Control Systems (IACS) Security series of standards and NIST SP800-82, Guide to Industrial Control Systems (ICS) Security. Research outcomes from the testbed will highlight specific cases where security technologies impact control performance as well as provide guidance to industry on best practices for implementing cybersecurity standards and guidelines without negatively impacting ICS performance. Research outcomes from the testbed will highlight specific cases where security technologies impact control performance as well as provide guidance to industry on best practices for implementing cybersecurity standards and guidelines without negatively impacting ICS performance.
