Resilience is one of the hottest topics of the moment, but for good reason. For most organizations, suffering a cyberattack is a matter of when, not if. Attackers are, lamentably, always one step ahead of defenders and, as such, responding to an attack and maintaining business operations have become arguably more important than protecting an organization in the first place. The NIST Cybersecurity Framework (CSF) is a crucial tool for organizations seeking to enhance their resilience, and its latest iteration has made it even more so. Let’s look at how.

What is the NIST CSF?

Before we discuss how it helps organizations enhance their cyber resilience, it is worth briefly explaining the NIST CSF and how it works. The NIST CSF is a widely adopted cybersecurity framework that was first published in 2014 to help organizations manage cybersecurity risks more effectively regardless of their size, sector, or maturity level. NIST released the most recent version of the framework, CSF 2.0, in early 2024.

The framework revolves around six core functions. Each function is critical in building a robust and resilient cybersecurity posture. They are:

• Govern:
  • The most recent addition to the NIST CSF, the govern function emphasizes the importance of governance activities and integrating cybersecurity into broader enterprise risk management strategies. Similarly, the function helps organizations ensure cybersecurity aligns with their mission, stakeholder expectations, regulatory requirements, and other business goals.
• Identify:
  • The identify function helps organizations better understand their environment and how it relates to cybersecurity risk. It provides guidance on identifying an organization’s environment, determining its associated risks, and managing them.
• Protect:
  • This function guides organizations in implementing safeguards to protect assets from cyber threats and ensure the continued delivery of critical services during a cybersecurity incident. It includes activities such as access control, data security, and training.
• Detect:
  • As the name suggests, the detect function helps organizations ensure they can detect cybersecurity threats. It suggests continuous monitoring and analysis to detect anomalies indicating a cybersecurity threat.
• Respond:
  • This function contains and mitigates the impact of a detected cybersecurity incident. It includes activities like incident analysis, communication, mitigation, and continuous improvement, which help organizations control, minimize damage, and prevent recurring threats.
• Recover:
  • Perhaps the most critical function for resilience – although we’ll get to this later – is the recovery function, which focuses on restoring normal operations after a cybersecurity incident. It involves activities like recovery planning, repairing affected systems, and communicating with stakeholders, ensuring the organization can swiftly return to business and learn from the incident to improve resilience.

What is Cyber Resilience?

Now that we understand the basics of the NIST CSF, we can move on to cyber resilience. Cyber resilience refers to an organization’s ability to protect itself from, detect, respond to, and recover from cyber attacks. In contrast to more traditional approaches to cybersecurity, which focus primarily on preventing cyber attacks, cyber resilience focuses more on ensuring an organization can continue operating in the event of a security incident. Cyber resilience is about maintaining business continuity and minimizing the impact of cyber threats.

How NIST CSF 2.0 Enhances Cyber Resilience

And now it’s time to put it all together. Here’s how the NIST CSF helps organizations enhance their cyber resilience.

Holistic Risk Management

The NIST CSF 2.0 – primarily through the govern function – helps organizations integrate a structured approach to cybersecurity with a broader risk management strategy. This integration enhances cyber resilience by ensuring that cybersecurity aligns with broader organizational risks – including financial and operational – and, ultimately, helps ensure that a business can continue delivering services, even after a cybersecurity incident.

Customization and Flexibility

Designed to be sector-neutral, the NIST CSF is flexible enough to meet any organization’s needs and circumstances. It allows users to develop cybersecurity strategies that align with, for example, risk tolerance, regulatory requirements, and business goals. This flexibility also ensures that the cybersecurity measures and their guides can augment as threats evolve.

Continuous Improvement

The NIST CSF encourages continuous improvement, suggesting that organizations should, for example, assess their cybersecurity posture regularly, identify gaps, and implement improvements. As cybercriminals constantly improve their tactics, such improvements are essential for protecting organizations and, hence, bolstering cyber resilience.

Enhanced Communication and Collaboration

The response function helps organizations improve communication between technical and non-technical stakeholders, including executives, managers, and security staff. It facilitates better decision-making, ensures all stakeholders understand their role in cybersecurity and what they must do if a security incident occurs, and provides a common language for discussing cybersecurity risks. Such communication and collaboration are crucial for resilience: getting an organization back up and running requires a swift, coordinated response.

Integration with Other Risk Management Programs

Perhaps the most attractive feature of the NIST CSF is that it is easily integrated with other risk management programs, meaning that organizations can quickly bolster their resilience by adopting supplementary frameworks or guidelines. Similarly, the NIST CSF is designed to support new and emerging technologies, such as artificial intelligence, in the risk management process, helping organizations stay resilient despite technological advancements.

Conclusion

The NIST CSF is an invaluable resource for organizations looking to bolster their cyber resilience, which – as threats grow increasingly frequent, sophisticated, and damaging – should be a priority for any business. While this article provides introductory information about the NIST CSF, successful implementation requires a deeper understanding of the framework.
