The NIST Cybersecurity Framework 2.0 represents a significant evolution in cybersecurity guidance. This article explores the key changes and provides practical implementation advice.
What's New in Version 2.0?
Enhanced Governance Function
The framework now includes a dedicated Govern function, emphasising the importance of cybersecurity governance at the organisational level.
Supply Chain Risk Management
Expanded guidance on managing cybersecurity risks in supply chains, reflecting the growing threat landscape.
Improved Flexibility
Enhanced flexibility to support organisations of all sizes and sectors.
The Six Core Functions
- Govern: Establish and monitor cybersecurity risk management
- Identify: Understand cybersecurity risks to systems and assets
- Protect: Implement safeguards for critical infrastructure
- Detect: Identify the occurrence of cybersecurity events
- Respond: Take action regarding detected events
- Recover: Restore capabilities impaired by events
Implementation Roadmap
Phase 1: Assessment
Evaluate your current cybersecurity posture against the framework.
Phase 2: Profile Development
Create target profiles that align with your organisation's risk tolerance and business objectives.
Phase 3: Gap Analysis
