Cybersecurity is an essential part of our interconnected world. It safeguards sensitive information, protects critical infrastructure and keeps cyber threats at bay.
Since 2014, these efforts have been guided by a robust framework created by the National Institutes of Standards and Technology at the U.S. Department of Commerce. Known as the NIST Cybersecurity Framework (CSF), this approach has helped businesses and organizations better understand, manage and reduce cybersecurity risk by protecting networks and data.
NIST recently released its Cybersecurity Framework (CSF) Version 2.0 draft. In this post, we’ll take a comprehensive look at NIST and the updates provided through the draft of CSF Version 2.0.
Understanding the NIST Cybersecurity Framework
NIST has played a central role in shaping cybersecurity through its guidance and standards. NIST’s involvement in this domain began decades ago, but it gained significant prominence with the issuance of the Federal Information Security Management Act (FISMA) in 2002, which required NIST to develop standards and guidelines for securing federal information systems. A 2013 Executive Order built on this work by tasking NIST with the formal development of an actual framework for voluntary use by private businesses and organizations outside of its existing Federal integration. This became the NIST CSF, which provides successful approaches for reducing cybersecurity risk.
The NIST CSF is structured around several key components, including the identified core functions of Identify, Protect, Detect, Respond and Recover.
These core functions serve as a foundation for a comprehensive security strategy. Within each function, a cumulative 23 categories delve into specific areas that provide actionable guidance for businesses and organizations. NIST also incorporates 108 subcategories that offer granular details and practical recommendations to help organizations effectively implement cybersecurity efforts. This hierarchical approach allows organizations to tailor their cybersecurity risk management efforts to their unique needs and risk profiles.
The NIST CSF includes two additional elements beyond the Framework Core: Implementation Tiers and the Framework Profiles.
- Implementation Tiers help organizations assess their current cybersecurity practices and determine the desired state, which can range from “Partial” (Tier 1) to “Adaptive” (Tier 4).
- The Framework Profiles allow organizations to create a roadmap for their cybersecurity efforts, set targets and establish priorities. These three elements offer a flexible and scalable approach to cybersecurity risk management.
The existing NIST CSF is vital in enhancing an organization’s cybersecurity posture in several ways. First and foremost, it offers a structured approach to managing cybersecurity risks. It provides a common language and methodology that facilitates stakeholder communication and collaboration. This results in a more holistic and integrated approach to cybersecurity internally and in cases where businesses must engage with outside stakeholders. Organizations can better protect their assets by identifying and addressing security gaps and vulnerabilities, including sensitive data, critical systems and/or intellectual property.
The Framework promotes a proactive stance by emphasizing detection and response capabilities, allowing organizations to mitigate threats and recover from incidents swiftly.
Ultimately, the NIST CSF empowers organizations to effectively assess their existing posture and plan a focused strategy toward improvement or sustainment depending on the overall risk appetite and compliance requirements.
What’s New in NIST 2.0?
Significant additions are included in the draft of the NIST CSF 2.0. These changes have been introduced to enhance the CSF’s relevance and applicability to various organizations. 
The most notable is the addition of a sixth pillar – Govern – to the existing five Core Functions.

This addition acknowledges the growing importance of governance in cybersecurity, emphasizing that it underpins all aspects of a robust cybersecurity program.
The Framework itself has also expanded its guidance, particularly concerning the implementation and customization of the framework to specific situations. It now offers more precise instructions for creating profiles, enabling organizations to better adapt the framework to their specific organizational needs.
The new version also emphasizes risk acceptance, risk prioritization and the selection of safeguards that align with the level of risk. This provides organizations with a more nuanced approach to cybersecurity risk management.
The NIST CSF 2.0 also reinforces the concept of continuous improvement by introducing the Improvement category in the Identity Function.
This encourages continuous organizational enhancement of existing cybersecurity practices and adaptation to evolving threats.
A revision to the implementation tiers focuses on governance, risk management and third-party considerations; it underlines the framework’s adaptability in serving organizations of all sizes and industries. Working with legal professionals who understand how to attain legitimate data and bring business sector knowledge can help organizations meet continuous improvement requirements.
NIST 2.0 Legal Compliance Considerations
Adherence to the NIST CSF can significantly mitigate legal risks and compliance issues for organizations and businesses.
The framework’s comprehensive guidelines and best practices for cybersecurity risk management provide a structured approach to identifying, protecting, detecting, responding to and recovering from cybersecurity incidents.
By implementing these practices, organizations can improve preparedness in the event of data breaches, protect against unauthorized access and other security incidents, and reduce business downtime and legal consequences of noncompliance, such as data or personal privacy violations.
The framework’s emphasis on risk assessment and continuous improvement allows organizations to proactively identify and address vulnerabilities before they escalate into legal issues or compliance violations. This can help demonstrate due diligence efforts and a commitment to integrating organizational cybersecurity best practices, which can be critical in defending a business or organization from a legal or compliance challenge.
Benefits of Implementing NIST Cybersecurity Framework Version 2.0
Implementing the NIST CSF 2.0 in a business or organization offers comprehensive advantages:
- It will significantly enhance an organization’s cybersecurity posture by providing a structured approach to identifying and mitigating risks. Adapting the NIST core functions helps organizations fortify their cyber defenses, detect threats more effectively, respond to incidents promptly and increase resilience when a cyberattack occurs.
- The framework will aid in improved risk management and decision-making. Through risk assessment and prioritization guidance, organizations can make more informed choices regarding resource allocation and security investments. This will bolster overall risk management and empower informed cybersecurity strategies.
- Adherence to the framework will provide a strong posture for demonstrating compliance and due diligence. By aligning with recognized security standards, organizations can present their commitment to cybersecurity best practices, which is invaluable in regulatory environments and building trust with stakeholders and customers.
Tips for a Successful NIST Cybersecurity Framework Implementation
Successfully implementing the NIST CSF requires a well-structured approach.
- It starts with a thorough assessment of your organization’s unique needs and capabilities. This will provide a clear understanding of the existing cybersecurity posture and what vulnerabilities currently exist.
- The next step is to create a tailored implementation plan that integrates these findings within the NIST CSF functions. This plan should be specific to the organization’s size, industry and risk profile while identifying the most critical assets and potential threats. It should also create an approach that allows for ongoing compliance and continuous improvement.
- Such plans must be dynamic, with the ability to respond to evolving threats and regulatory changes. This requires regular review and updates. Collectively, these efforts will help foster a culture of vigilance.
The existing NIST CSF provides a strong framework for establishing a robust and adaptable cybersecurity program. The enhancements released as part of the CSF 2.0 draft strengthen critical areas and expand the framework to enhance organizational cybersecurity efforts further.
