Are you worried about managing your organization’s cybersecurity risks? The National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) can be a valuable tool to help assess and mitigate those risks.
In this article, we’ll provide a comprehensive overview of the NIST Cybersecurity Framework, including its functions, categories, methodology, and practical applications. By the end of this article, you’ll have a good understanding of how to use the CSF to manage your organization’s cybersecurity risks, improve your security posture, and align with industry best practices.
What is the NIST Cybersecurity Framework?
The NIST Cybersecurity Framework is a voluntary risk-based approach to managing cybersecurity risks. Developed in 2014 by the National Institute of Standards and Technology (NIST), the framework is widely used by organizations to identify, assess, and manage cybersecurity risks in their operations and supply chains. The NIST Cybersecurity Framework consists of three main components:
- Framework Core, which is a set of cybersecurity activities and outcomes that serve as a common language for organizations to manage cybersecurity risks
- Framework Implementation Tiers, which help organizations prioritize and achieve their cybersecurity goals in a way that is consistent with their risk management needs
- Framework Profiles, which help organizations develop a snapshot of their current cybersecurity activities and outcomes and serve as a reference point for improvements
The framework’s five core functions are Identify, Protect, Detect, Respond, and Recover, which are further subdivided into categories and subcategories to help organizations prioritize and manage their cybersecurity activities.
For small businesses or organizations without dedicated cybersecurity teams, the NIST Cybersecurity Framework can be especially helpful to establish a baseline and improve the overall cybersecurity posture. With the voluntary framework’s help, organizations can improve the ability to manage risk related to their equipment, systems, and data.
Framework Core
The Framework Core is the heart of the NIST CSF and consists of five functions – Identify, Protect, Detect, Respond, and Recover – that serve as a common language for categorizing cybersecurity activities and outcomes across different sectors and organizations.
- Identify – involves developing an understanding of the organization’s cybersecurity posture, assessing potential risks, and developing a risk management plan.
- Protect – involves implementing policies, procedures, and safeguards to reduce cybersecurity risks to the organization’s systems and their data.
- Detect – involves the development and implementation of strategies for identifying cyber events and anomalous network activities.
- Respond – involves planning and executing measures to respond to identified cybersecurity incidents.
- Recover – involves planning and implementing processes to restore systems, data, and assets following a cybersecurity incident.
Each function has several categories, which are further subdivided into subcategories. The subcategories provide details on the activities and outcomes necessary to implement the category fully.
By using the framework core, organizations can prioritize cybersecurity activities and investments based on their potential impact on the organization’s cybersecurity posture.
Framework Implementation Tiers and Profiles
The Framework Implementation Tiers help organizations apply the NIST CSF in a way that is consistent with their risk management needs and cybersecurity goals.
- Tier 1 – Partial: Organizations at this level have an inconsistent approach to manage cybersecurity risks or have not yet established an approach to cybersecurity risk management.
- Tier 2 – Risk-Informed: Organizations at this level have established an approach to managing cybersecurity risk management that is aligned with their risk management practices.
- Tier 3 – Repeatable: Organizations at this level have the necessary policies, procedures, and practices in place to manage cybersecurity risk management effectively.
- Tier 4 – Adaptive: Organizations at this level are agile and adaptive in managing their cybersecurity risks and can take the necessary measures quickly to respond to new and emerging cybersecurity threats.
The Framework Profiles, on the other hand, help organizations to develop a profile that describes their current cybersecurity activities and outcomes, which can then be compared to a target or baseline profile to close gaps and improve their cybersecurity posture.
- Current Profile: This is a snapshot of the organization’s previous activities, including policies, procedures and resources, and the overall cybersecurity risk management approach.
- Target Profile: This is the organization’s desired cybersecurity posture after addressing identified gaps compared to their Current Profile. The difference between the two Profiles describes gaps that the organization seeks to address.
Small businesses and large organizations can use implemented Tiers and Profiles to prioritize their cybersecurity investments and keep up with the latest cybersecurity risks and threats.
Conclusion
The NIST Cybersecurity Framework is a valuable tool for organizations, especially those in critical infrastructure services, to manage cybersecurity risk. It provides a common language, prioritization framework, and methodology to organize, assess, and manage cybersecurity risks and outcomes.
By using the CSF, organizations can improve their cybersecurity posture, strengthen their risk management capabilities, and align with industry standards and best practices. The framework’s voluntary and adaptable nature allows organizations of all sizes and needs to apply its principles and methodologies to their unique programmatic needs and compliance with contractual requirements.
NIST provides online learning opportunities, virtual workshops, and public comment opportunities to hear from stakeholders, solicit feedback, and improve the CSF over time. By prioritizing the five core functions and using the framework’s taxonomy to build their cybersecurity policy, organizations can strengthen their response plan, board-level reporting, and criticality analysis.
In conclusion, the NIST Cybersecurity Framework serves as a roadmap to help organizations manage their cybersecurity risk and prioritize their cybersecurity investments. By using a risk-based approach, organizations can identify and mitigate cybersecurity risks in their operations and supply chains, strengthen their cybersecurity posture, and align with industry standards and best practices.
