Which of the following activities is included in the post-incident review phase?

Determining the root cause of the incident is a critical activity in the post-incident review phase. This step focuses on understanding why the incident occurred to prevent recurrence. Developing steps to mitigate risks is part of the lessons learned and improvement phase, which follows root cause analysis. Validating evidence accuracy is an ongoing task throughout the incident response process, particularly during analysis and containment, not exclusively post-incident. Reestablishing system configuration is part of the recovery phase, which occurs before the post-incident review.
