It will then describe how to construct a timeline by correlating various cloud logs (e.g., CloudTrail, VPC Flow Logs, GuardDuty) and system events, normalizing timestamps. Finally, it must articulate a robust chain of custody process, including documentation, hashing, and secure storage, to maintain evidentiary integrity for legal and HR purposes.

14. Q14

    What evidence would you preserve first and how would you avoid contaminating it? In your answer, cover scope boundaries, time-zone normalization, and hash validation

    AdvancedForensicsIBM-specific

    Context: IBM is asked to investigate a file share after a new local administrator created on several endpoints is reported in a hybrid cloud platform team. The client requires evidence suitable for legal review.

    How to answer: The highest priority evidence to preserve first is volatile memory (RAM) and network state, as these are lost on shutdown. To avoid contamination, a forensically sound acquisition tool should be used, booting from a trusted live environment or using a hardware write-blocker for disk images. Scope boundaries must be clearly defined, focusing on the affected system(s) and relevant timeframes, while all timestamps should be normalized to UTC to prevent misinterpretation. Finally, cryptographic hashes (e.g., SHA256) of acquired images and tools must be calculated and verified to ensure data integrity and authenticity throughout the process.

15. Q15

    What evidence would you preserve first and how would you avoid contaminating it? In your answer, cover artifact reliability, collection order, and timeline construction

    Lead/ConsultantForensicsIBM-specific

    Context: IBM is asked to investigate an ERP server after LSASS memory access from an unsigned binary is reported in a managed detection and response engagement. The client wants minimal business disruption.

    How to answer: The primary evidence to preserve first is volatile data, as it is most susceptible to loss. This includes CPU registers, cache, routing tables, process tables, network connections, and memory (RAM). To avoid contamination, a forensically sound collection methodology must be used, such as live acquisition tools that write to an external, write-protected drive, minimizing writes to the compromised system. Artifact reliability is ensured by using trusted tools and hashing collected data, while collection order prioritizes volatility to maintain data integrity for accurate timeline construction.
