Due to the nature of cyber-physical systems (CPSs), incidents can quickly lead to physical harm to people, destruction of property or environmental disasters. Gartner analysts predict that incidents will rapidly increase in the coming years due to a lack of security focus and spending currently aligning to these assets. Gartner defines CPSs as systems that are engineered to orchestrate sensing, computation, control, networking and analytics to interact with the physical world (including humans).
“Regulators and governments will react promptly to an increase in serious incidents resulting from failure to secure CPSs, drastically increasing rules and regulations governing them,” said Katell Thielemann, research vice president at Gartner. “In the U.S., the FBI, NSA and Cybersecurity and Infrastructure Security Agency (CISA) have already increased the frequency and details provided around threats to critical infrastructure-related systems, most of which are owned by private industry. Soon, CEOs won’t be able to plead ignorance or retreat behind insurance policies.”
Cost will be significant for organizations
Gartner predicts that the financial impact of CPS attacks resulting in fatal casualties will reach over $50 billion by 2023. Even without taking the actual value of a human life into the equation, the costs for organizations in terms of compensation, litigation, insurance, regulatory fines and reputation loss will be significant.
With operational technology, smart buildings, smart cities, connected cars and autonomous vehicles evolving, incidents in the digital world will have a much greater effect in the physical world as risks, threats and vulnerabilities now exist in a bidirectional, cyber-physical spectrum. However, many enterprises are not aware of CPSs already deployed in their organization, either due to legacy systems connected to enterprise networks by teams outside of IT, or because of new business-driven automation and modernization efforts.
