The adoption of Internet of Things (IoT) devices has resulted in billions of devices being connected to networks and the internet. With the increasing number of IoT devices comes an increasing number of cybersecurity concerns. In light of this, the National Institute of Standards and Technology (NIST) has developed a framework to help organizations address cybersecurity risks, including those associated with IoT devices.
The NIST Cybersecurity Framework is a set of best practices, standards, and guidelines that help organizations manage and reduce cybersecurity risks. The framework consists of five functions: identify, protect, detect, respond, and recover.
The first function, identify, helps organizations understand their cybersecurity risks associated with IoT devices and other systems. This function includes developing an inventory of devices, assessing the risks associated with each device, and creating a plan to manage those risks. This is important because it enables organizations to understand the scope of their IoT networks and the security risks involved.
The protect function focuses on safeguards that prevent or limit the impact of a potential cybersecurity event. This includes implementing security controls, such as firewalls and access controls, that limit access to sensitive data or devices. For IoT devices, this can include implementing strong authentication protocols, such as two-factor authentication, to prevent unauthorized access.
The detect function includes monitoring the network and devices for security events and anomalies. This function involves using technologies that can detect threats, such as intrusion detection systems and security information and event management systems. For IoT devices, this can include implementing device monitoring solutions that can detect when a device is behaving abnormally or is compromised.
The respond function involves taking action in response to a cybersecurity incident. This includes developing an incident response plan that outlines the steps to be taken when a security event occurs, such as isolating an affected device or data, and communicating the incident to relevant stakeholders.
The final function, recover, focuses on restoring normal operations after a cybersecurity event or incident. This includes restoring data and systems to their previous state and identifying areas for improvement to prevent similar incidents from occurring in the future.
The NIST Cybersecurity Framework is a valuable tool for organizations looking to secure their IoT networks. By following the framework’s best practices and guidelines, organizations can better identify, protect, detect, respond to, and recover from cybersecurity risks associated with IoT devices. By doing so, they can reduce the likelihood of a security event occurring and minimize its impact if it does happen.
