Understanding the CSF Core: The Heart of the Framework
The Core is the heart of the NIST CSF and contains cybersecurity activities and desired outcomes that are common across sectors and organizations. It consists of six high-level Functions: Govern, Identify, Protect, Detect, Respond, and Recover. Within each Function are Categories and Subcategories that provide specific cybersecurity outcomes.
The Six Functions
The six Functions represent a high-level, strategic view of the lifecycle of an organization’s management of cybersecurity risk. They provide a concise representation of the outcomes an organization should achieve through cybersecurity risk management:
- Govern – Develop and communicate the organization’s cybersecurity risk management policies and strategy. The Govern function is newly added in NIST CSF 2.0, and is crucial for establishing an organization’s approach to managing cybersecurity risk. It involves defining roles, responsibilities, and the process for integrating cybersecurity into the overall enterprise risk management. This strategic approach helps ensure that efforts across the Identify, Protect, Detect, Respond, and Recover functions are aligned with the organization’s goals, compliance requirements, and stakeholder expectations. Key activities within this function focus on developing a comprehensive cybersecurity strategy, establishing governance structures to support cybersecurity efforts, and monitoring the effectiveness of cybersecurity policies and practices.
- Identify – Develop an organizational understanding to manage cybersecurity risk to systems, people, assets, data, and capabilities. The activities in the Identify Function are foundational for effective use of the Framework. Understanding the business context, the resources that support critical functions, and the related cybersecurity risks enables an organization to focus and prioritize its efforts. Categories within this Function include Asset Management, Business Environment, Governance, Risk Assessment, and Risk Management Strategy.
- Protect – Develop and implement appropriate safeguards to ensure the delivery of critical services. The Protect Function supports the ability to limit or contain the impact of a potential cybersecurity event. Categories within this Function include Identity Management and Access Control, Awareness and Training, Data Security, Information Protection Processes and Procedures, Maintenance, and Protective Technology.
- Detect – Develop and implement appropriate activities to identify the occurrence of a cybersecurity event. The Detect Function enables the timely discovery of cybersecurity events. Categories within this Function include Anomalies and Events, Security Continuous Monitoring, and Detection Processes.
- Respond – Develop and implement appropriate activities to take action regarding a detected cybersecurity incident. The Respond Function supports the ability to contain the impact of a potential cybersecurity incident. Categories within this Function include Response Planning, Communications, Analysis, Mitigation, and Improvements.
- Recover – Develop and implement appropriate activities to maintain resilience plans and restore any capabilities or services that were impaired due to a cybersecurity incident. The Recover Function supports timely recovery to normal operations to reduce the impact of a cybersecurity incident. Categories within this Function include Recovery Planning, Improvements, and Communications.
Together, these six Functions provide a high-level, strategic view of cybersecurity risk management’s lifecycle. They guide organizations in managing threats and protecting critical assets through prevention, detection, and timely response.
Structuring the Framework: Profiles and Tiers
Organizational Profiles: Customizing Your Cybersecurity Strategy
Organizational profiles are a vital component of the NIST CSF 2.0 for tailoring the framework to your organization’s specific needs. Profiles allow organizations to customize the framework by prioritizing and selecting controls from the core that are most relevant to their risk management priorities, threats, and vulnerabilities.
Organizations can develop target profiles to strategically focus their cybersecurity efforts on a subset of activities representing their priorities. Current and desired target profiles can be compared to support cybersecurity risk management decisions and measure improvement over time. Organizational profiles are flexible and adaptable as circumstances change.
Tiers: Calculating Your Cybersecurity Maturity
The tiers component of NIST CSF 2.0 provides context on how an organization views cybersecurity risk and how cybersecurity practices are integrated into broader risk management. The tiers describe the degree of rigor, formality, and integration of cybersecurity into broader risk management based on business needs.
There are four tiers, ranging from Partial (Tier 1) to Adaptive (Tier 4). A higher tier indicates greater cybersecurity maturity and understanding of cybersecurity risk. However, a higher tier is not necessarily better. Organizations should determine the tier that appropriately supports their risk management needs. Tiers help assess progress in managing cybersecurity risk over time.
Implementing NIST CSF 2.0
The most important step in leveraging NIST CSF 2.0 is developing a robust implementation plan and strategy. Organizations should start by reviewing their current cybersecurity policies, controls, and maturity level to identify gaps that CSF 2.0 can help fill. Teams can use the Framework Core’s Functions, Categories, and Subcategories as a reference when mapping their existing cybersecurity initiatives and determining where improvements are needed.
Organizations should consider all relevant stakeholders and business processes when developing an implementation roadmap. Cross-functional collaboration is key – IT teams will need to work closely with legal, risk management, executive leadership, and others. The implementation plan should have defined milestones, success metrics, resource needs, and timelines.
Putting the plan into action requires buy-in at all levels of the organization. Training programs, especially for non-technical employees, build workforce cyber readiness. Once the framework is implemented, conducting audits or maturity assessments helps verify that cybersecurity controls are operating as intended. Ongoing maintenance and updates to the program are also critical as threats evolve.
Supplemental resources that provide guidance on implementing the CSF include NIST’s online CSF Implementation Guidance, the CSF Starter Implementation Guide, and for federal agencies – the Federal CSF Implementation Quick Start Guide. Utilizing these references helps ensure a smooth and effective Framework deployment.
