The updated NIST CSF 2.0 is an industry-agnostic framework that helps organisations of any size manage and reduce their cybersecurity risk. It is built around six core functions (Govern, Identify, Protect, Detect, Respond and Recover) and uses Profiles and Tiers to tailor it to your needs. Benefits include a stronger security posture, fewer attacks, easier compliance, clearer communication and cost savings.
Staying ahead of threats is a challenge for organisations of all sizes. Reported global security incidents rose 69.8% between February and March 2024, so a structured approach to cybersecurity is essential. The National Institute of Standards and Technology (NIST) created the Cybersecurity Framework (CSF) to give companies an industry-agnostic way to manage and reduce cybersecurity risk. It was updated in 2024 to NIST CSF 2.0, a more streamlined and flexible version that builds on its predecessor. This guide simplifies it for small and large businesses alike.
The Core: Six Continuous Functions
At the heart of CSF 2.0 is the Core, made up of six concurrent and continuous Functions. Together they give a high-level strategic view of cybersecurity risk and how your organisation manages it, which supports a dynamic approach to threats.
- Govern: Set and oversee your cybersecurity strategy, policies, roles and responsibilities. This function sits across the other five and shapes how your organisation manages risk.
- Identify: Understand your assets, cyber risks and vulnerabilities. You need to know what you are protecting before you can install safeguards.
- Protect: Implement safeguards to deter, detect and mitigate risks, such as firewalls, intrusion detection systems and data encryption.
- Detect: Catch incidents early to minimise damage, with mechanisms to identify and report suspicious activity.
- Respond: Know the steps to take during an incident, including containment, eradication, recovery and lessons learned.
- Recover: Restore normal operations after an incident through data restoration, system recovery and business continuity planning.
Profiles and Tiers
Profiles and Tiers help you tailor the framework to your needs, risk tolerance and resources. A Profile aligns the Functions, Categories and Subcategories with your business requirements. Tiers show how your organisation views cybersecurity risk and the processes it has in place to manage it, ranging from Partial (Tier 1) to Adaptive (Tier 4).
Benefits of NIST CSF 2.0
- Improved cybersecurity posture: The guidance helps you build a more comprehensive and effective program.
- Reduced risk of cyberattacks: Identifying and mitigating risks lowers the likelihood of an attack.
- Enhanced compliance: The framework aligns with many industry standards and regulations.
- Improved communication: It provides a common language for discussing cyber risk across your organisation.
- Cost savings: Preventing attacks and reducing the impact of incidents saves money.
Getting Started
- Familiarise yourself with the framework: Read the NIST CSF 2.0 publication and learn the Core Functions and categories.
- Assess your current posture: Identify any gaps or weaknesses.
- Develop a cybersecurity plan: Outline how you will put the framework into practice in your organisation.
- Seek professional help: A managed IT services partner can offer guidance and support.
Follow these steps and you can begin deploying NIST CSF 2.0 while improving your cybersecurity posture.
