The technique that examines the causes for attacks using security forensics techniques and post-mortem analysis is best described as a retrospective approach. This method involves analyzing past security incidents to understand how and why breaches occurred, which helps in identifying vulnerabilities and patterns that can be addressed in the future. By using security forensics, analysts can gather data from a compromised system, thoroughly investigate the incident, and learn critical lessons.

This approach is particularly effective because it not only helps in refining defense measures but also contributes to the overall security strategy by leveraging historical incident data. Such insights can lead to improvements in security policies, incident response, and employee training, ultimately enhancing the organization's ability to prevent similar incidents from happening again.

Other approaches, such as the preventive and proactive approaches, focus on anticipating threats and taking measures to avoid them before they can cause harm. The reactive approach, while it deals with responding to incidents after they occur, does not necessarily involve the in-depth analysis characteristic of a retrospective approach. Therefore, the retrospective method is key for understanding past events in order to bolster future defenses.
