Structuring cyber risk management with the NIST CSF 2.0
The NIST Cybersecurity Framework (CSF), version 2.0, is a voluntary, globally recognized framework for organizing cyber risk management. Unlike ISO 27001 or PCI DSS, it is not certifiable in the strict sense: it is a common language for structuring, prioritizing and communicating an organization’s security posture, including to non-technical management.
Six functions, including one new in version 2.0
Version 2.0 added the Govern function to the five historical functions (Identify, Protect, Detect, Respond, Recover) - an explicit recognition that governance (strategy, roles, responsibilities, supplier risk management) determines the effectiveness of everything else. Without clear governance, the technical measures of the other functions lack overall consistency and management sponsorship.
A prioritization framework, not a checklist
The NIST CSF does not say *how* to implement a specific measure - it helps identify *where* the most critical gaps are, using maturity levels (Tiers) and target profiles defined by the organization itself according to its risk context. It is a useful starting point for prioritizing an action plan before, or alongside, a more prescriptive framework such as ISO 27001.
