Which of the following activities is associated with the response phase of incident management?

The response phase of incident management focuses on actions taken after a security incident has been detected. This phase involves executing predetermined processes to handle the incident, mitigate its impact, recover from it, and prevent future occurrences. Specifically, executing an incident response plan is central to this phase, as it outlines the necessary steps and measures that should be implemented when an incident occurs, including identification, containment, eradication, and recovery.

The other activities, such as conducting audits, implementing authentication measures, and planning for disaster recovery, are critical components of overall security and risk management but do not fall under the immediate actions taken during the incident response phase. Conducting audits might help identify vulnerabilities, implementing authentication measures enhances security posture, and planning for disaster recovery is essential for maintaining business continuity, but these actions are typically part of preparedness and preventive strategies rather than direct responses to active incidents.
