What are the implications of Zero Trust for securing manufacturing and industrial control systems?

Zero trust has significant implications for protecting manufacturing environments and industrial control systems by adopting a strict access control model that requires all users, devices, and applications to be verified and authenticated before being granted access to the network. This approach minimizes the risk of unauthorized access and reduces the attack surface by assuming that threats could be both external and internal. It helps to protect critical infrastructure, sensitive data, and production systems from cyber threats, such as malware, ransomware, and unauthorized access attempts. Implementing zero trust principles in manufacturing environments and industrial control systems can enhance cybersecurity posture, improve visibility into network activity, and strengthen overall resilience against cyber attacks.
