Which of the following activities is part of the Respond (RS) function of the NIST Cybersecurity Framework?

The Respond (RS) function of the NIST Cybersecurity Framework is focused on taking action regarding a detected cybersecurity event. This function involves developing and implementing the appropriate activities to take after a cybersecurity incident has occurred. Key activities in this function include incident response planning, communications during and after the event, and analysis to determine the extent and impact of the incident.

The choice of a specific activity as part of the Respond function must align with these core objectives. While threat analysis is certainly an important component in understanding and preparing for potential threats, it primarily aligns with the Identify function, which focuses on understanding and managing cybersecurity risks.

In contrast, system patch management, data recovery strategies, and other related activities are aimed at restoring capabilities and services after an incident and preventing future incidents, which are integral to the Respond function. Successful incident recovery and response involve not just understanding what went wrong but also actively addressing the fallout and planning for effective recovery.

Therefore, the correct answer encompasses all activities related to the Respond function, where data recovery strategies and system patch management play critical roles in mitigating the impact of incidents and enhancing the organization's resilience against future threats.
