Five Functions of NIST-Supported Cybersecurity Framework

A well-structured framework is essential for establishing effective, consistent policies and strategies. This applies to many areas, including network security. Listed below is a look into the National Institute of Standards and Technology (NIST) cybersecurity framework, which outlines steps to help safeguard your business.

The NIST framework comprises five necessary functions: Identify, Protect, Detect, Respond, and Recover.

Identify Threats

You can’t defend against a threat you don’t understand. Begin by identifying the potential threats to your business assets and resources. This includes understanding the hardware, software, and supply chain that support your business, as well as adhering to regulatory guidelines to protect these resources. Knowing what to protect, and against whom, helps you assess risk and determine appropriate safeguards.

Protect Against Threats

Once you understand the risks, implement protective measures such as:

• Access controls to limit unauthorized access to data and systems.
• Data security to ensure confidentiality and controlled access to critical information.
• Routine maintenance to keep systems updated and secure, maximizing uptime.
• Staff training aligned with their access levels.

Additionally, consider a business continuity strategy—beyond NIST recommendations—to identify your minimum operational requirements.

Detect Threats

It’s not about whether an attack will happen, but when. Your cybersecurity solutions should be able to detect threats in real-time, alerting you to any suspicious activity. These alerts are imperative to ensuring your defenses are functioning effectively. If you aren’t detecting potential threats as they emerge, you could be left to deal with major vulnerabilities.

Respond to Threats

The goal is to detect and respond to threats quickly, reducing their impact on your operations. Have a clear, reliable incident response policy in place. Address the immediate threat, mitigate residual risks, and keep communication open with affected parties like customers, vendors, employees, and local authorities.

After addressing an incident, review the attack to learn how to improve your defenses for the future.

Recover from Threats

Even after neutralizing a threat, recovery is an essential step. Use your business continuity plan to restore interrupted services and implement a well-defined recovery strategy to get your company back on track. Focus on restoring critical systems, learning from the incident, and improving to prevent future issues. Keep all stakeholders, including customers, staff, and partners, informed of your recovery progress.

Protecting Your Business

While these five steps may seem extensive, they highlight the importance of cybersecurity to your business’ resilience. Don’t wait until an incident occurs—prepare now with solid strategies and systems.
