Strengthening Cybersecurity in Manufacturing: The Path to a Defensible Architecture
Summary: Dragos published a whitepaper on cybersecurity challenges in manufacturing OT environments, citing poor network security controls, mixed high-tech and legacy connectivity, a lack of in-house expertise, limited visibility and monitoring, and the need to interconnect IT and OT systems. The paper applies the SANS Five ICS Cybersecurity Critical Controls - an ICS incident response plan, a defensible architecture, visibility and monitoring, secure remote access, and risk-based vulnerability management - and emphasizes network segmentation as central to a defensible architecture.
Key Takeaway: The source notes that indirect effects such as disrupted label printers or altered labels can halt manufacturing processes, and that flat network topologies and unmonitored remote connections leave OT exposed to adversaries.
