The plan acknowledges that NIST SP 800-207 was designed for IT networks, not 24/7 industrial systems, and focuses on three phases: mapping assets and identities at the IT/OT boundary (days 1-30), containing vendor remote access with quick wins like MFA and brokered connections (days 31-60), and building a maturity scorecard aligned with TSA, NERC CIP-013, and CISA requirements (days 61-90). The approach emphasizes framing zero trust as a functional principle rather than an abstract architecture, focusing on IT/OT convergence points like jump hosts and remote access paths, and tying actions to existing regulatory requirements. ## Full article daily.dev links to this article rather than hosting it.
