Question

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

Options

  • ADetermining the root cause of the incident
  • BDeveloping steps to mitigate the risks of the incident
  • CValidating the accuracy of the evidence collected during the investigation
  • DReestablishing the compromised system's configuration and settings

Explanation

Root cause analysis is the defining activity of the post-incident review phase - after the incident has been contained and resolved, the team conducts a structured "lessons learned" or after-action review to understand why and how the incident occurred, which is precisely what determining root cause accomplishes.

  • B is wrong because developing mitigation steps occurs during the containment and eradication phase, while the incident is still active.
  • C is wrong because validating evidence accuracy happens during the investigation/analysis phase, while the incident is being worked.
  • D is wrong because reestablishing compromised system configurations is recovery, which precedes the post-incident review.

Memory tip: Think of post-incident review as a retrospective - the dust has settled, systems are back online, and now the team asks "why did this happen and how do we prevent it?" Root cause = retrospective = post-incident.
