OT Security for Sawmills, Shops, and Ag Operations: The Part of Cyber That Breaks Production

A plain-language OT cybersecurity guide for northern Alberta SMBs (sawmills, agriculture, oilpatch shops and similar) that contrasts OT and IT risk, lists the most common OT attack vectors (engineer laptop bridging, weak vendor remote access, flat networks, legacy unpatched controllers), and prescribes achievable controls: firewall-based segmentation and VLANs, an asset inventory, a recorded jump host for vendor access, documented patching windows and vendor-access policies, cost estimates for baseline protections, and guidance on when to engage an OT specialist.
