Which of the NIST Cybersecurity Framework functions calls for quick action on the part of an organization's cybersecurity team?

The Respond function of the NIST Cybersecurity Framework is designed to enable organizations to take immediate and effective actions when a cybersecurity incident occurs. This function highlights the importance of having a well-planned approach for responding to incidents, ensuring that the cybersecurity team can quickly address and mitigate the impact of an incident. It includes activities such as managing communications during and after the event, analyzing the response to ensure effective resolution, and implementing improvements to prevent similar incidents in the future.

The focus of the Respond function is on the immediacy and effectiveness of actions taken to handle incidents when they arise, which is critical for minimizing damage and protecting organizational assets. Thus, the emphasis on quick action makes this function essential for maintaining an organization's cybersecurity posture in the face of threats.
