Which function involves preparing for a future incident in cybersecurity?

The function that involves preparing for a future incident in cybersecurity is the "Recover" function. This aspect encompasses strategies and plans developed to ensure that an organization can return to its normal operations effectively after an incident occurs. Recovery planning is a proactive measure that involves identifying potential incidents, creating response strategies, and establishing protocols to restore systems and data after a breach or attack.

By focusing on recovery, organizations prepare themselves for the inevitable possibility of a cyber incident. This involves establishing backup systems, optimizing disaster recovery plans, and ensuring that critical data can be restored quickly. Additionally, recovery planning is often tied to lessons learned from past incidents to improve future responsiveness.

While the other options—such as identifying vulnerabilities, implementing protections, and detecting threats—are also vital components of a comprehensive cybersecurity strategy, they do not specifically focus on the preparation for future incidents in the same way that recovery does. Each of these functions plays a role in managing cybersecurity, but recovery is unique in its emphasis on future preparedness after an incident has occurred.
