NIST CSF 2.0: Govern Function

### Executive Summary — NIST CSF 2.0 and the Govern Function: This article explains the 2024 update to the NIST Cybersecurity Framework (CSF 2.0), which formally adds Govern as a sixth core function (alongside Identify, Protect, Detect, Respond, and Recover). It outlines the Govern subcategories — organizational context, risk management strategy, roles/responsibilities/authorities, policy, oversight, and cybersecurity supply chain risk management — and explains why elevating governance strengthens enterprise risk-driven cybersecurity, improves senior leadership engagement, and supports implementation through principles of risk transparency, communications, ownership, and decision-making.
