NIST Cybersecurity Framework

The NIST Cybersecurity Framework is a guideline from the National Institute of Standards and Technology for systematically managing cybersecurity risk. Version 2.0 (released February 2024) introduces the new Govern core function and broadens the scope beyond critical infrastructure to all organization types. The framework now consists of six core functions: Govern, Identify, Protect, Detect, Respond, and Recover. It also defines four implementation tiers and organizational profiles for individual customization.

NIST CSF takes a risk-based approach that is more flexible than the control-based structure of ISO 27001. It can be used across industries, is freely available, and provides a clear structure for prioritizing measures. It also integrates seamlessly with ISO 27001, BSI IT-Grundschutz, and regulatory requirements such as DORA and NIS2. ADVISORI frequently recommends an integrated approach where NIST CSF serves as the strategic framework and ISO 27001 provides operational controls.

Implementation follows five phases: First, we conduct an assessment of the current cybersecurity posture and create a current-state profile. Second, we jointly define the target profile and prioritize gaps using a risk-based gap analysis. Then we implement measures across all six core functions. Finally, we establish continuous monitoring and regular reviews for ongoing maturity improvement.

The six core functions are: Govern (managing cybersecurity strategy and policies), Identify (recognizing and assessing risks), Protect (implementing safeguards), Detect (identifying security events), Respond (reacting to detected incidents), and Recover (restoring affected services). Govern is new in version 2.0 and ensures that cybersecurity is anchored as an enterprise-wide governance topic.

With CSF 2.0, the NIST Framework addresses organizations of all sizes and industries – not just critical infrastructure operators. It is particularly relevant for financial services firms (complementing DORA), critical infrastructure operators (complementing NIS2), international enterprises, and organizations that want to efficiently consolidate multiple compliance requirements under one roof.

NIST CSF serves as an overarching framework that maps to existing regulatory requirements. ADVISORI creates cross-framework mappings that identify overlaps between NIST CSF, ISO 27001, DORA, and NIS2. This avoids duplicated audit efforts and creates a unified governance structure. The six core functions cover the essential requirements of all mentioned frameworks.

Costs depend on organization size, IT landscape complexity, and the target maturity level. An initial gap analysis typically takes two to four weeks. Full implementation spans three to twelve months depending on the starting point. ADVISORI offers a complimentary 30-minute initial consultation to estimate the individual effort and create a realistic roadmap.
