Explanation:
Appropriate people need to be notified; however, one must first validate the incident. Containing the effects of the incident would be completed after validating the incident. Developing response strategies for systematic attacks should have already been developed prior to the occurrence of an incident.

= The primary objective of performing a post-incident review is to identify the root cause of the incident, which is the underlying factor or condition that enabled or facilitated the occurrence of the incident. Identifying the root cause helps to understand the nature and origin of the incident, and to prevent or mitigate similar incidents in the future. A post-incident review also aims to evaluate the effectiveness and efficiency of the incident response process, identify lessons learned and best practices, and recommend improvements for the incident management policies, procedures, controls, and tools. However, these are secondary objectives that depend on the identification of the root cause as the first step.
Re-evaluating the impact of incidents is not the primary objective of performing a post-incident review, as it is already done during the incident response process. The impact of incidents is the extent and severity of the damage or harm caused by the incident to the organization's assets, operations, reputation, or stakeholders. Re-evaluating the impact of incidents may be part of the post-incident review, but it is not the main goal.
Identifying vulnerabilities is not the primary objective of performing a post-incident review, as it is also done during the incident response process. Vulnerabilities are weaknesses or flaws in the system or network that can be exploited by attackers to compromise the confidentiality, integrity, or availability of the information or resources. Identifying vulnerabilities may be part of the post-incident review, but it is not the main goal.
Identifying control improvements is not the primary objective of performing a post-incident review, as it is a result of the root cause analysis. Controls are measures or mechanisms that are implemented to protect the system or network from threats, reduce risks, or ensure compliance with policies and standards. Identifying control improvements is an important outcome of the post-incident review, but it is not the main goal. Reference = ISACA CISM: PRIMARY goal of a post-incident review should be to?
