Industry 4.0 is built on connectivity through the connected devices installed in the manufacturing environment, regardless of whether they are operated wireless or wired. To assure continuous, safe and sustainable operations, the devices and their connections must operate safely and securely, which means they need to be resilient against potential errors and attacks. For this to happen, multiple stakeholders must contribute in different ways according to their role as a product manufacturer, system integrator, operator and plant owner.
This webinar will explain the risks that exist when cybersecurity is not addressed properly and how cybersecurity can become an asset with a high return on investment. Cyber-physical systems (CPS), as applied in Industry 4.0, change the world – and cybersecurity is key to preventing outages, lawsuits and destroying brand reputation.
Organizations should utilize good hygiene techniques such as network segmentation and intermediary systems that serve as “middlemen” to gather, protect, and provide information. Additionally, technologies such as trusted platform modules or hardware security modules should be incorporated into future devices to provide robust cryptologic support, hardware authentication, and attestation (that is, detect when unauthorized changes are made to the device). By combining this approach with robust access controls, mission-critical operations technology is secured at the application points and endpoints to protect its data and processes.
Where data must be available in part, or the data sensitivity is high, other industries such as financial services provide examples of protecting information. While on its path to interconnectedness, the financial services industry realized that it is no longer typically adequate to focus solely on security to address data privacy and confidentiality risks, and that these techniques should be married with other techniques, such as data governance. Indeed, organizations should perform risk assessments across their environment, including enterprise, DSN, industrial control systems, and connected products, and use those assessments to determine or update their cyber risk strategies. Taken together, all of these approaches can help to identify where higher levels of prevention are warranted as connectivity increases.
