Key ideas in Digital Forensics: Following the Electronic Trail
- Opening files or folders updates 'Last Accessed' timestamps in the metadata
- RAM is volatile and is wiped the moment the computer loses power
- Any interaction with the OS can trigger background write operations
- Hard drives store data semi-permanently on physical platters or flash chips
- Forensic integrity requires that the original evidence remains bit-for-bit identical
- The Order of Volatility dictates that the most 'fragile' data is saved first
- The impact of interacting with a live system on metadata
- Prioritizing evidence collection based on how fast it disappears
- A write-blocker physically prevents the workstation from sending 'write' signals to the drive
- Operating systems often automatically write hidden files or index data when a drive is plugged in
- Using a write-blocker ensures the forensic copy is a perfect, untainted duplicate
- The arrangement of cables can show which devices were connected during the crime
- Identifying essential physical evidence at the scene
- Pulling the power cord is a last-resort move to stop active data destruction
- The function and necessity of a write-blocker
- Standard shutdown procedures allow the OS to finish 'cleaning up' or deleting files
