Business Impact Governance: NIS2 Alignment – Public Overview (v1.0)

A compact technical addendum and open-access public overview outlining the conceptual alignment between Directive (EU) 2022/2555 (NIS2) requirements and the Business Impact Governance (BIG) framework. This document addresses the operational governance gap between technical monitoring data and accountable executive oversight under NIS2. It presents a structured alignment matrix connecting management accountability (Article 20), risk-management measures (Article 21), incident severity scoring, business continuity, and material supply-chain dependencies to an objective, governed decision baseline (P = B + S + T). Notice: This public edition introduces the conceptual problem space and architectural alignment principles only. Detailed technical scoring functions, CMDB/ITSM database schemas, automated audit evidence logic, and proprietary contractual artifacts are intentionally excluded from this edition.
