NIST Cybersecurity Framework
A risk-based approach to managing cybersecurity across any organization
// What is NIST CSF?
The NIST Cybersecurity Framework provides a flexible, risk-based approach to cybersecurity that organizations of any size or sector can adopt. Originally developed for critical infrastructure, CSF has become the de facto standard for security program development across industries.
Version 2.0, released in February 2024, adds Govern as a sixth core function, emphasizing cybersecurity governance and supply chain risk management. The framework doesn't prescribe specific controls but provides a common language for understanding, managing, and expressing cybersecurity risk.
NIST CSF's broad adoption makes it particularly valuable for organizations navigating multiple compliance requirements, as it maps to numerous other frameworks including ISO 27001, HIPAA, and PCI-DSS.
// Inside the Regulation
NIST CSF 2.0 organizes cybersecurity activities into six core Functions, each containing Categories and Subcategories defining specific outcomes. Organizations implement controls achieving these outcomes based on their risk profile and Implementation Tier.
Govern (GV)
New in version 2.0, this function establishes cybersecurity as an enterprise risk managed at the highest organizational levels.
Organizational Context
Understanding the organization's mission, stakeholder expectations, and dependencies informing cybersecurity risk decisions.
Risk Management Strategy
Establishing risk tolerance, priorities, and the organization's approach to managing cybersecurity risk.
Cybersecurity Supply Chain Risk Management
Processes for identifying, assessing, and managing supply chain risks across the organization.
Roles and Responsibilities
Establishing accountability for cybersecurity across the organization including workforce and third parties.
Identify (ID)
Develop organizational understanding to manage cybersecurity risk to systems, assets, data, and capabilities.
Asset Management
Identify and manage hardware, software, data, and systems enabling the organization to achieve business objectives.
Risk Assessment
Understand cybersecurity risks to operations, assets, and individuals through threat and vulnerability identification.
Improvement
Identify improvements to organizational cybersecurity through evaluation of current practices.
Protect (PR)
Develop and implement appropriate safeguards to ensure delivery of critical services.
Identity Management and Access Control
Limit access to assets and capabilities to authorized users, processes, and devices.
Awareness and Training
Educate personnel to perform their cybersecurity duties consistent with policies and procedures.
Data Security
Manage data consistent with risk strategy including confidentiality, integrity, and availability protections.
Platform Security
Protect hardware, software, and services through technical security mechanisms.
Technology Infrastructure Resilience
Manage security architectures to protect asset confidentiality, integrity, and availability.
Detect (DE)
Develop and implement appropriate activities to identify the occurrence of a cybersecurity event.
Continuous Monitoring
Monitor assets to identify cybersecurity events and verify protective measure effectiveness.
Adverse Event Analysis
Analyze anomalies and events to understand attack targets and methods.
Respond (RS)
Develop and implement appropriate activities to take action regarding a detected cybersecurity incident.
Incident Management
Processes ensuring response to detected cybersecurity incidents including triage, containment, and eradication.
Incident Analysis
Analysis conducted to understand the scope and impact of detected incidents.
Incident Response Reporting and Communication
Coordination and communication activities with internal and external stakeholders during incidents.
Incident Mitigation
Activities to prevent expansion of an incident and resolve it.
Recover (RC)
Develop and implement appropriate activities to maintain resilience and restore capabilities impaired by a cybersecurity incident.
Incident Recovery Plan Execution
Restore systems and assets affected by cybersecurity incidents to normal operation.
Incident Recovery Communication
Coordinate restoration activities with internal and external stakeholders.
Note: NIST CSF uses Implementation Tiers (1-4) to characterize organizational approaches to cybersecurity risk management, from Partial (Tier 1) to Adaptive (Tier 4). Organizations develop Framework Profiles describing their current state and target state, using the gap to prioritize improvements.
// Who Must Comply
- 1 Federal contractors and suppliers (often required)
- 2 Critical infrastructure operators (energy, healthcare, financial services, transportation)
- 3 Organizations seeking structured security program development
- 4 Companies pursuing cyber insurance (commonly referenced in applications)
- 5 Any organization wanting a recognized framework for security program maturity
// Key Requirements
Risk Assessment
Identify and assess cybersecurity risks to operations, assets, and individuals
Asset Management
Maintain inventories of hardware, software, data, and systems supporting business objectives
Protective Controls
Implement safeguards including access control, awareness training, and data security
Detection Capabilities
Deploy monitoring and detection mechanisms to identify cybersecurity events
Incident Response
Establish and test procedures for responding to and recovering from incidents
Continuous Improvement
Evaluate and improve security practices based on lessons learned and changing threats
// Enforcement & Penalties
NIST CSF itself is voluntary with no direct enforcement mechanism. However, federal contracts increasingly require CSF alignment, and failure to implement appropriate cybersecurity may trigger liability under other regulations or contractual obligations.
No direct regulatory fines (voluntary framework)
Examples:
- Loss of federal contract eligibility for non-aligned organizations
- Increased liability exposure if breach occurs without reasonable security practices
- Difficulty obtaining or maintaining cyber insurance coverage
- Customer requirements making CSF alignment a business necessity
// Cyber Insurance Impact
Cyber insurers frequently reference NIST CSF in applications and underwriting. Demonstrating alignment with CSF functions—particularly around risk assessment, detection, and incident response—can improve coverage terms. Insurers view CSF adoption as evidence of mature risk management practices, potentially reducing premiums and improving policy limits.
