Digital Forensic Certification Practice Exam

Which of the following is used to identify potential root causes of an event in a system?

1. Payload Correlation

2. Graph-Based Approach

3. Rule-Based Approach

4. Fingerprint-Based Approach

The correct answer is: Graph-Based Approach

The graph-based approach is effective in identifying potential root causes of an event in a system due to its visual representation and ability to depict relationships among various components. This method typically involves creating a visual model of the system, where nodes represent different entities—such as processes, events, or devices—and edges denote the interactions or communications between them. By analyzing these connections, forensic investigators can trace the flow of events leading to a specific outcome or anomaly, helping to pinpoint the underlying causes. Graph-based approaches also facilitate complex analysis, such as finding patterns and correlations among multiple system events. This holistic view aids in understanding how different parts of a system interrelate, which is crucial in forensic investigations where identifying the root cause is essential for remediation and prevention of future incidents. The approach's ability to map out scenarios in a structured yet flexible manner makes it a powerful tool in digital forensics.
