The Manufacturing IT Leader's Guide to Delightfully Paranoid Security

Real incidents from DataTel CISO Ernest Murry's book, translated for the plant floor: the vendor tunnel nobody rotated, the device IT never knew existed, and the backup that would fail a real restore test.

This excerpt is drawn directly from real incidents in Ernest Murry's book Delightfully Paranoid, translated specifically for people who own manufacturing IT and OT security. Across five sections, it walks through the vendor remote-access tunnel nobody audits, the unmanaged device sitting on the network that IT never inventoried, why a single flat network turns a printer into a domain-controller pivot path, and why "we have backups" isn't the same as "we can restore the MES by end of shift." Each section ends with a specific, doable Monday-morning action.
