NIST's National Cybersecurity Center of Excellence (NCCoE) has released Security Segmentation in a Small Manufacturing Environment (NIST Cybersecurity Whitepaper 28).
What is this paper about?
As manufacturers are increasingly targeted in cyberattacks, any gaps in cybersecurity leave small manufacturers vulnerable to attacks. Small manufacturers tend to operate facilities with limited staff and resources, often causing cybersecurity to fall by the wayside as something that costs too much time and money. Additionally, bringing together various cybersecurity standards, frameworks, and guides to derive a coherent action plan is a challenge even for those experienced in cybersecurity.
Security segmentation is a cost effective and efficient security design approach for protecting cyber assets by grouping them based on their communication and security requirements. This paper outlines a practical six-step approach, incorporating the NIST Cybersecurity Framework (CSF) and NIST IR 8183 Cybersecurity Framework: Manufacturing Profile (“CSF Manufacturing Profile”), that manufacturers can follow to implement security segmentation and mitigate cyber vulnerabilities in their manufacturing environments.
