During an incident response to a data breach in a company's AWS environment, a forensic investigator is tasked to analyze and extract data from different storage types for further examination. What would be the most appropriate and effective course of action given that Amazon S3, EBS, and EFS were used?
During an incident response to a data breach in a company's AWS environment, it is critical to preserve the integrity of the data while extracting it for analysis. Snapshotting EBS volumes ensures that a complete and unaltered copy of the data at a specific point in time is preserved, which is essential for forensic analysis. Similarly, creating snapshots of S3 buckets helps in retaining a point-in-time copy of the data. Mounting the EFS to a Linux instance allows for comprehensive analysis, as EFS can be attached to multiple instances and provides a simple and scalable way to access the data. Therefore, creating snapshots of EBS volumes and S3 buckets while mounting EFS to a Linux instance is the most appropriate and effective course of action.
D. Snapshot the affected EBS volumes and S3 buckets, and mount EFS to a Linux instance for analysis aligns with the practices recommended in the CHFI v10 textbook. The textbook emphasizes the importance of creating snapshots of EBS volumes for forensic analysis to preserve the state of the data. It also suggests that Amazon EFS can be mounted to a Linux instance for detailed examination. For S3 buckets, the textbook would support securing and extracting data appropriately, but the snapshotting and mounting approach ensures comprehensive coverage and maintains the integrity of the evidence.
Amazon EC2 instances use EBS volumes that act like virtual hard drives In the event of a security incident, investigators must take an offline snapshot of the EBS volume from the affected EC2 instance to acquire forensic evidence
