Security Segmentation in a Small Manufacturing Environment

What Security Segmentation in a Small Manufacturing Environment requires

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. This paper introduces security segmentation as a cost-effective and efficient approach to mitigate cyber vulnerabilities for small manufacturing environments. Security segmentation is the grouping of assets into security zones according to the cyber protection they need and placing appropriate safeguards around these security zones. It is an approach for protecting assets by grouping them based on both their communication and security requirements. The intended audience is managers of information technology and operational technology (IT/OT) systems at small manufacturing organizations, including roles like company owner, operations manager, and technical resources such as network and security architects. The core obligation is to follow a six-step approach: 1) identify a list of assets, 2) assess risk and create security zones, 3) determine the risk level for the security zones, 4) map communications between the security zones, 5) determine security controls for the security zones, and 6) create a logical security architecture diagram. The security architecture resulting from these activities serves as a foundational preparation step for additional security strategies like Zero Trust.
