Which of the following best describes a category of the Recover (RC) function of the NIST Cybersecurity Framework?

The category of communication with all stakeholders is essential in the Recover function of the NIST Cybersecurity Framework because effective communication is critical to ensuring that all relevant parties are informed during and after a cybersecurity incident. This involves sharing information about the incident, recovery efforts, and lessons learned, which is vital for restoring operations and maintaining trust.

This communication includes keeping internal stakeholders, such as management and employees, informed about the situation and necessary actions. It also involves external communications with customers, vendors, and regulatory bodies, ensuring transparency and compliance with legal obligations. By maintaining open lines of communication, organizations can facilitate a quicker recovery process, improve organizational resilience, and enhance future incident responses.

The other choices, while important to overall cybersecurity practices, do not directly encapsulate a core aspect of the Recover function as outlined by the NIST Cybersecurity Framework. Regular software updates, for instance, are typically part of the Protect function aimed at preventing incidents rather than recovering from them. Offensive security measures focus on proactively identifying vulnerabilities, and the isolation of affected systems is generally a response strategy during the Respond phase of an incident rather than a recovery-focused activity.
