How to combat cybersecurity threats to process safety
April 1, 2019
Effective change management for control systems is key to avoiding vulnerabilities
Investigations into several major plant accidents by theĀ U.S. Chemical Safety BoardĀ and theĀ U.K. Health and Safety ExecutiveĀ have identified improper modifications to industrial control system (ICS) alarms, control loops and safety instrumented systems (SISs) as either a major contributing factor or a root cause of an incident.
Meanwhile, the fast-growing threat of cyberattacks by nation states or criminals seeking ransoms has created an urgent need to lock down and protect the ICS configuration. Furthermore, unmanaged change initiated by internal actors can lead to the same catastrophic consequences that an external bad actor can impart on a production facility.
Eddie Habibi, PAS Global, explains howĀ defining and implementing a basic cybersecurity strategy that includes change management of the ICS configuration will help protect against cyber vulnerabilities on our sister website, ChemicalProcessing.com.
