NIST Cybersecurity Framework (CSF 2.0)


In today’s digital age, cybersecurity has become a top priority for businesses of all sizes. With the increasing frequency and sophistication of cyber threats, organisations need effective frameworks to manage cybersecurity risks and protect their assets. One such framework gaining widespread adoption is the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) 2.0. In this article, we’ll provide a detailed overview of the CSF 2.0, its key requirements, and its impacts on businesses.

The NIST Cybersecurity Framework (CSF) is a set of voluntary guidelines, best practices, and standards designed to help organisations manage and improve their cybersecurity posture. Developed by NIST, a division of the U.S. Department of Commerce, the CSF provides a flexible and risk-based approach to cybersecurity, enabling organisations to assess, prioritise, and manage cybersecurity risks effectively.

The CSF 2.0 consists of five core functions: Identify, Protect, Detect, Respond, and Recover. Each function is further divided into categories and subcategories, providing a comprehensive framework for cybersecurity risk management. Here’s an overview of the key requirements and provisions of each function:

  • Identify: This function involves understanding the organisation’s cybersecurity risks, assets, and vulnerabilities. Key activities include asset management, risk assessment, and the development of cybersecurity policies and procedures.
  • Protect: The Protect function focuses on implementing safeguards to protect against cybersecurity threats. This includes activities such as access control, data encryption, security awareness training, and secure configuration management.
  • Detect: Detecting cybersecurity incidents in a timely manner is essential for minimising damage and disruption. The Detect function includes activities such as continuous monitoring, anomaly detection, and incident response planning.
  • Respond: In the event of a cybersecurity incident, organisations must be prepared to respond effectively. The Respond function involves activities such as incident response coordination, containment, mitigation, and communication.
  • Recover: After a cybersecurity incident, organisations need to recover and restore their operations as quickly as possible. The Recover function includes activities such as data backup and recovery, business continuity planning, and post-incident analysis.

The NIST CSF 2.0 was published on the 26th of February 2024 and applies internationally.

Does the CSF 2.0 affect my business?

The adoption of the NIST CSF 2.0 can have several significant impacts on businesses:

  • Improved Cybersecurity Posture: By following the guidelines and best practices outlined in the CSF, organisations can strengthen their cybersecurity posture and better protect their sensitive information and assets from cyber threats.
  • Regulatory Compliance: Many regulatory bodies and industry standards organisations, such as the Payment Card Industry Data Security Standard (PCI DSS) and the Health Insurance Portability and Accountability Act (HIPAA), reference the NIST CSF as a recommended framework for cybersecurity compliance. Therefore, adopting the CSF can help businesses meet regulatory requirements and demonstrate compliance.
  • Enhanced Risk Management: The CSF provides a structured approach to cybersecurity risk management, enabling organisations to identify, assess, and prioritise cybersecurity risks effectively. This can help businesses allocate resources more efficiently and focus on addressing the most critical cybersecurity threats.
  • Increased Customer Confidence: Implementing the CSF can enhance customer confidence by demonstrating a commitment to cybersecurity best practices and a proactive approach to protecting customer data and privacy.

By adopting the CSF 2.0, businesses can improve their cybersecurity posture, enhance regulatory compliance, and build customer trust. As cyber threats continue to evolve, the CSF remains a valuable tool for organisations seeking to stay ahead of the curve and safeguard their digital assets and operations.

Do I need the CSF 2.0 in my ISO Compliance Register?

The NIST CSF 2.0 is applicable to businesses of all sizes and across various industries. However, certain sectors, such as finance, healthcare, and critical infrastructure, may have specific regulatory requirements or compliance obligations that make the CSF 2.0 particularly relevant. Additionally, businesses that handle sensitive or personal information, such as financial institutions, healthcare providers, and government agencies, may benefit greatly from implementing the CSF to protect against cyber threats and data breaches.

If this includes your business or organisation we strongly recommend including the CSF 2.0 in your ISO Compliance Register.

Legislation related to the CSF 2.0

Legislation related to the CSF 2.0 include:

  • Data Protection Act 2018
  • Regulation (EU) 2016/679 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (GDPR)
  • The Cyber (Sanctions) (Overseas Territories) Order 2020
