What threat-hunting step involves mitigating the immediate threat and taking corrective actions?

The response/resolution step in threat hunting is focused on addressing and mitigating the immediate threat that has been identified. This phase is crucial because it involves taking the necessary actions to contain and eliminate the threat, thereby reducing its potential impact on the organization. It encompasses not only remediation efforts to stop the threat but also corrective actions to prevent recurrence.

In addition to identifying and resolving the incident, this step may include informing relevant stakeholders, implementing changes to security policies or controls, and updating systems to ensure they are fortified against similar threats in the future. This proactive approach not only addresses the current issue but also enhances the overall security posture of the organization.

While hypothesis formulation helps in defining what to look for during the hunt, and collecting and processing data are foundational tasks that precede the identification of threats, the investigation phase centers around understanding the nature and scope of the threat. Response/resolution is distinct as it explicitly focuses on action taken after a threat has been detected.
