Manufacturers are increasingly targeted in cyber-attacks. Small manufacturers are particularly vulnerable due to limitations in staff and resources to operate facilities and manage cybersecurity. Security segmentation is a cost-effective and efficient security design approach for protecting cyber assets by grouping them based on both their communication and security requirements.
This paper outlines a six-step approach that manufacturers can follow to implement security segmentation and mitigate cyber vulnerabilities in their manufacturing environments. The security architecture resulting from the security segmentation design activities is a foundational preparation step for additional security strategies like Zero Trust.
