Understanding the NIST Cybersecurity Framework
The NIST Cybersecurity Framework (CSF) is a voluntary framework that provides cyber governance and risk management guidance to organizations to improve their ability to prevent, detect, and respond to cyber attacks. The framework is industry-agnostic, flexible, and scalable, enabling organizations of all sizes and industries to implement it effectively.
According to the NIST CSF 2.0, issued in February 2024, the framework is composed of three primary components: the CSF Core, the CSF Organizational Profiles, and the CSF Tiers.
CSF Core:
This is the heart of the NIST CSF, consisting of functions, categories, and sub-categories that outline specific cybersecurity activities and outcomes that can help organizations manage their cybersecurity risks. There are six core functions:
- Govern
- Identify
- Protect
- Detect
- Respond
Recover
These functions are further divided into categories and subcategories that provide a comprehensive roadmap for managing cybersecurity risk.
CSF Organizational Profile:
Organizational profiles describe an organization’s current and desired/target cybersecurity posture. This helps in identifying the gaps between the current and the target profiles and developing an action plan to address those gaps.
CSF Tiers:
These tiers help organizations understand the degree to which their cybersecurity risk governance and management practices exhibit the characteristics defined in the NIST CSF. They range from Tier 1 (Partial) to Tier 4 (Adaptive), reflecting an increasing degree of rigor and sophistication in managing cybersecurity risk.
What are NIST CSF Maturity Levels?
NIST CSF maturity levels are understood in the context of the framework tiers, namely Partial (Tier 1), Risk-Informed (Tier 2), Repeatable (Tier 3), and Adaptive (Tier 4), which provide a structured way to measure the effectiveness and sophistication of an organization's cybersecurity practices.
It is important to note here that while the tiers represent the progression from a lower maturity level to a higher maturity level, an organization can choose to be at a certain tier depending on its business requirements, risk tolerance, and resources.
Let’s look at the maturity levels in detail:
Partial: Level 1
At the Partial level, an organization lacks structured cybersecurity governance and risk management processes. Practices are often ad hoc and inconsistent, with a primarily reactive approach to cybersecurity. The ability to identify, evaluate, and mitigate risks, including those associated with suppliers, is limited, resulting in significant gaps and weaknesses in the cyber defense mechanism.
Risk-Informed: Level 2
The Risk-Informed level indicates that an organization has begun to adopt a more structured approach to cybersecurity governance and risk management. While cyber risk management practices are approved by the management, they are not established and implemented across the enterprise. Additionally, there is an awareness of risks and some proactive measures in place but the overall approach may still lack comprehensive integration across all departments.
Repeatable: Level 3
At the Repeatable level, an organization has standardized its cybersecurity governance and risk management processes and practices and implemented them across the enterprise. These processes are consistent and repeatable, meaning they can be reliably reproduced and executed. The organization regularly reviews and updates cybersecurity practices based on the changes in business/mission requirements, threats, and technological landscape.
Adaptive: Level 4
The Adaptive level represents the pinnacle of cybersecurity maturity. Organizations at this level have a proactive approach to cyber risk management, characterized by continuous improvement and dynamic adjustment of cybersecurity measures. They understand the relationship between cybersecurity risks and organizational objectives and take that into account when making decisions. The IT team regularly updates practices to address new risks and challenges, ensuring a resilient and robust cybersecurity framework.
Steps to Improve Your Organization’s NIST CSF Maturity
The NIST CSF maturity model serves as a tool for assessing and improving an organization’s cybersecurity practices. It provides a structured approach to evaluate current capabilities, identify gaps, and implement improvements.
Here are the key steps for organizations to improve their NIST CSF maturity:
Self-Assessment: Assessing Current State
The first step is conducting a comprehensive self-assessment to assess the current state. This process involves evaluating current cybersecurity practices against the NIST CSF functions, categories, and subcategories. It helps identify strengths, weaknesses, and gaps in existing practices, allowing you to prioritize areas that need improvement. The assessment helps in identifying the organization's current Implementation Tier.
Organizations can utilize available tools such as the NIST CSF online assessment tool, cybersecurity maturity models, and third-party audit services. These tools can help streamline the assessment process, providing detailed reports and insights into your current maturity level.
Goal Setting: Setting Target Profile
Once the self-assessment is complete, organizations then establish their Target Profile, which outlines the desired state of their cybersecurity practices. These goals should be aligned with an organization’s risk tolerance, resources, and strategic objectives.
For example, a goal might be to Partial to Risk-Informed maturity level within a year. Breaking down these goals into smaller, manageable tasks helps ensure steady progress and maintain momentum.
Implementation: People, Process, Technology
With the Current and Target Profiles in hand, organizations can create a roadmap for improvement. This roadmap prioritizes actions based on their impact and feasibility, ensuring that resources are allocated effectively to areas that will yield the greatest benefit in terms of risk reduction and cybersecurity enhancement. It involves implementing changes across three key areas: people, process, and technology:
- People: Invest in training and awareness programs to enhance the cybersecurity knowledge and skills of your employees. Encourage a culture of cybersecurity awareness, where everyone understands their role in protecting the organization’s assets. Regular training sessions, workshops, and simulations can help reinforce good practices and keep employees informed about the latest threats and mitigation strategies.
- Process: Develop and refine policies, procedures, and protocols to ensure they are robust, effective, and aligned with the NIST CSF. Establish clear roles and responsibilities for cybersecurity, ensuring that all processes are well-documented and regularly reviewed. Implementing incident response plans, risk management frameworks, and continuous monitoring protocols are essential steps in this area.
- Technology: Leverage advanced cyber risk management tools and software solutions to streamline the process of identifying, assessing, mitigating, and monitoring cyber risks and threats.
The NIST CSF maturity model is not a one-size-fits-all solution but a flexible tool that organizations can tailor to their unique needs and circumstances.
