With a mission to secure the connected enterprise for its customers and its own operations, Rockwell took steps to reduce OT technical debt, address outdated technology, remediated high-risk assets and solidified security controls across its manufacturing ecosystems. Rockwell’s ultimate goal was to become a world-class leader in OT cybersecurity by meeting the very extensive 62443-3-3 set of industrial automation and control systems (IACS) security requirements, following the 62443-2-1 processes and controls. Rockwell’s next goal was to help customers achieve the same results for their own plant operations. Rockwell created a dedicated enterprise OT cybersecurity team focused on securing Rockwell’s manufacturing facilities. After an extensive site analysis, a structured cyber framework was outlined that could continually mature the company’s security posture by following industry standards including IEC 62443. The team achieved the certification goal using their own products, services and partner network and demonstrated to customers that they can help them on their own journey. The creation of Rockwell’s dedicated team and security framework has resulted in a manufacturing programme that instils a continuous improvement culture for maturing cyber security in OT environments resulting in manufacturing that’s resilient, scalable, maintainable, secure and certifiable.
