Continuous Improvement of Incident Response Capabilities

A.

The activity that the incident team lead has executed is a "lessons learned review" (option A).

A lessons learned review is a process of evaluating an incident response action or event to identify the strengths and weaknesses of the response strategy and tactics that were employed, and to learn from these experiences. It is an essential component of incident response and is critical for improving the organization's incident response capabilities.

The purpose of a lessons learned review is to determine what worked well during the response, what could have been done better, and what should be done differently in the future to improve the response. It is a comprehensive process that involves evaluating every aspect of the incident response, from the initial detection and analysis of the incident to the final resolution and reporting.

During the review, the incident team lead and other members of the response team may discuss various topics such as the following:

• The effectiveness of the response plan, including any policies, procedures, or guidelines that were followed or revised
• The adequacy of the incident response team's training and preparation for the incident
• The efficiency of the incident response process, including communication, coordination, and documentation
• The accuracy and completeness of the incident analysis, including the identification of the source of the incident and the extent of the damage or impact
• The effectiveness of the containment, eradication, and recovery actions taken during the incident response
• The effectiveness of the reporting and communication of the incident response to stakeholders such as management, customers, and law enforcement
• Any legal, regulatory, or compliance issues that arose during the incident response.

After the review, the incident team lead and other stakeholders should develop an action plan to address the identified weaknesses and implement changes to improve incident response capabilities. The action plan may include revising the incident response plan, providing additional training to incident response team members, or making changes to the organization's security posture to prevent similar incidents from occurring in the future.

Therefore, a lessons learned review is critical for continuous improvement of an organization's incident response capabilities, and it is an essential activity for any incident response team to undertake after a data-leakage incident.
