Which NIST Cybersecurity Framework function emphasizes the protection of IT infrastructure?

The Protect (PR) function of the NIST Cybersecurity Framework is focused specifically on safeguarding critical infrastructure and information systems. This function emphasizes the implementation of appropriate safeguards to ensure the delivery of critical infrastructure services. It includes measures for access control, awareness and training, data security, maintenance, protective technology, and other relevant protections, all directed at preventing and mitigating cybersecurity risks.

This function aims to mitigate the effects of potential cybersecurity-related events, ensuring that organizations can prevent or minimize the impact of a threat. By focusing on protective measures, organizations can create an environment that is resilient to attacks and capable of maintaining operations despite incidents, thereby securing their IT infrastructure from various threats.

The other functions listed serve different purposes. The Respond (RS) function deals with developing and implementing appropriate activities to take action regarding a detected cybersecurity incident. The Recover (RC) function focuses on resilience and timely restoration of services after a cybersecurity event. The Identify (ID) function involves understanding the organizational environment and managing cybersecurity risks to systems, assets, data, and capabilities. While all these functions are crucial to a comprehensive cybersecurity strategy, only the Protect function specifically emphasizes the active protection of IT infrastructure.
