#ZeroTrust for #ICS is not the same as zero trust for IT: in ICS we talk about #ZeroTrustArchitecture because we need to make sure we address: 1-Organizational trust, 2-Computer trust-related Controls and 3-Physical trust (both Network & devices access).
It is #ZeroTrustArchitecture or #ZeroTrustModel or #ZeroTrustFramework for #OT / #ICS.
