What is the NIST Cybersecurity Framework?​

The NIST CSF is a risk-based approach to managing cybersecurity that provides a common taxonomy and mechanism for organizations to:

  • Describe their current cybersecurity posture
  • Target their desired cybersecurity posture
  • Identify and prioritize opportunities for improvement
  • Assess progress toward their target state
  • Communicate cybersecurity risk internally and externally

Key Characteristics​

  • Voluntary and Flexible: Adaptable to any organization regardless of size or sector
  • Risk-Based: Focuses on business-driven cybersecurity outcomes
  • Technology Neutral: Not prescriptive about specific technologies or solutions
  • Living Framework: Designed to evolve with the threat landscape
  • Cost-Effective: Leverages existing standards and practices
  • Outcomes-Focused: Emphasizes desired cybersecurity outcomes rather than compliance checklists

Core Functions​

The NIST CSF 2.0 framework is structured around six core functions that provide a high-level view of the cybersecurity lifecycle:

1. Govern (GV) - NEW in CSF 2.0​

Establishes and monitors the organization's cybersecurity risk management strategy, expectations, and policy.

Categories:

  • Organizational Context (GV.OC)
  • Cybersecurity Strategy (GV.CS)
  • Cybersecurity Policy (GV.PO)
  • Cybersecurity Roles & Responsibilities (GV.RR)
  • Cybersecurity Risk Management (GV.RM)
  • Cybersecurity Supply Chain Risk Management (GV.SC)

2. Identify (ID)​

Develop an organizational understanding of cybersecurity risk to systems, people, assets, data, and capabilities.

Categories:

  • Asset Management (ID.AM)
  • Business Environment (ID.BE)
  • Governance (ID.GV)
  • Risk Assessment (ID.RA)
  • Risk Management Strategy (ID.RM)
  • Supply Chain Risk Management (ID.SC)

3. Protect (PR)​

Develop and implement appropriate safeguards to ensure delivery of critical services.

Categories:

  • Identity Management and Access Control (PR.AC)
  • Awareness and Training (PR.AT)
  • Data Security (PR.DS)
  • Information Protection Processes and Procedures (PR.IP)
  • Maintenance (PR.MA)
  • Protective Technology (PR.PT)

4. Detect (DE)​

Develop and implement appropriate activities to identify the occurrence of a cybersecurity event.

Categories:

  • Anomalies and Events (DE.AE)
  • Continuous Security Monitoring (DE.CM)
  • Detection Processes (DE.DP)

5. Respond (RS)​

Develop and implement appropriate activities to take action regarding a detected cybersecurity incident.

Categories:

  • Response Planning (RS.RP)
  • Communications (RS.CO)
  • Analysis (RS.AN)
  • Mitigation (RS.MI)
  • Improvements (RS.IM)

6. Recover (RC)​

Develop and implement appropriate activities to maintain plans for resilience and restore capabilities or services that were impaired due to a cybersecurity incident.

Categories:

  • Recovery Planning (RC.RP)
  • Improvements (RC.IM)
  • Communications (RC.CO)

Target Users and Applications​

Primary Target Organizations​

  • Critical Infrastructure: Energy, water, transportation, communications, healthcare
  • Federal Agencies: Government departments and agencies
  • State and Local Governments: Municipal and regional government entities
  • Private Sector: Companies of all sizes across all industries
  • Educational Institutions: Universities, colleges, and school districts
  • Healthcare Organizations: Hospitals, clinics, and healthcare systems
  • Financial Services: Banks, credit unions, and financial institutions
  • Small and Medium Businesses: Organizations with limited cybersecurity resources

Business Drivers for NIST CSF​

  • Risk Management: Systematic approach to cybersecurity risk identification and management
  • Regulatory Alignment: Foundation for meeting various regulatory requirements
  • Executive Communication: Common language for discussing cybersecurity with leadership
  • Vendor Risk Management: Framework for assessing third-party cybersecurity practices
  • Insurance Requirements: Some cyber insurance providers reference NIST CSF
  • Industry Standards: Many sector-specific guidelines built upon NIST CSF
  • Cost-Effective Security: Leverage existing investments and standards

Implementation Tiers​

The Framework defines four Implementation Tiers to help organizations understand their current approach to cybersecurity risk management:

Tier 1: Partial​

  • Risk Management Process: Ad hoc, reactive
  • Integrated Risk Management: Limited awareness
  • External Participation: Minimal information sharing

Tier 2: Risk Informed​

  • Risk Management Process: Risk-informed but not organization-wide
  • Integrated Risk Management: Some integration with enterprise risk management
  • External Participation: Aware of cybersecurity supply chain risks

Tier 3: Repeatable​

  • Risk Management Process: Organization-wide approach with regular updates
  • Integrated Risk Management: Integrated into organization-wide risk management
  • External Participation: Understands dependencies and partners

Tier 4: Adaptive​

  • Risk Management Process: Adaptive and improved through lessons learned
  • Integrated Risk Management: Real-time, integrated risk management
  • External Participation: Proactive information sharing and collaboration

Framework Profiles​

Profiles represent the alignment of the Framework Core with the business requirements, risk tolerance, and resources of a specific organization.

Current Profile​

  • Represents "as-is" state
  • Shows current cybersecurity posture
  • Identifies existing capabilities and gaps

Target Profile​

  • Represents desired "to-be" state
  • Aligned with business objectives and risk tolerance
  • Guides prioritization of cybersecurity investments

Gap Analysis​

  • Comparison between Current and Target Profiles
  • Identifies improvement opportunities
  • Supports roadmap development and resource allocation
