Access to operational systems, from networks to controllers, is typically granted based on implied trust. But threat actors can leverage excess trust to breach networks, often using stolen credentials.
Zero Trust improves cybersecurity by assuming no implicit trust and by strengthening perimeters around business critical assets. Zero Trust is considered the leading strategy to help protect critical assets from evolving threats today - and Rockwell Automation can help you navigate it.
Productivity management systems, like enterprise asset management and ERP applications, all require data from the plant floor. This data continues to increase operational efficiency. Yet threat actors can leverage the same connectivity to breach networks.
Deploying a secure boundary, called an Industrial Demilitarized Zone (IDMZ), to separate business systems from production operations is a best practice for helping protect ICS. This boundary helps prevent breaches in IT from accessing OT networks and controllers.
Along with IDMZ, Zero Trust micro segmentation can then further guard business critical assets, using firewalls, highly granular access and identity policies and other steps.
A connected enterprise requires a comprehensive approach to network segmentation, including IDMZ, and an expert partner who understands how to apply strategies such as Zero Trust in industrial environments. Rockwell Automation has the industrial expertise to keep your critical assets safe and secure, without jeopardizing uptime or productivity.
The US Executive Order on improving the nation’s cybersecurity from May 2021, explicitly calls for Critical Infrastructure sectors to adopt more effective cybersecurity measures, including Zero Trust solutions.
Many Critical Infrastructure organizations operate on legacy systems without modern cybersecurity controls in place, such as network segmentation, Multi-factor Authentication, frequent asset inventories, or effective OT patching. With evolving threats to core services like energy, food, and water increasing, the added protection of a Zero Trust approach can help protect public safety and wellbeing by removing excess trust and by adding key safeguards around networks, assets and data.
Start today with a professional risk and Vulnerability Assessment and learn where your most critical gaps are. Rockwell Automation will then help you design a cybersecurity program to better secure your operations – and the services we all rely on.
Zero Trust is built around a core five-step process that enables the “never trust, always verify” goal to be realized. These five steps are:
When Protect Surfaces and their digital assets are each treated as the entire production process in a Zero Trust approach, it can support the achievement of the ISA/IEC 62443 security standard.
Rockwell Automation experts supply crucial OT cybersecurity expertise around modern industrial security practices like Zero Trust, and around industry-accepted standards like ISA/IEC 62443.
