RAM data significance in Digital Forensics
Last semester, I made memory dump file for analyzing trace remaining after using Tor-browser. However, my boss said it is useless because that file was available to get only when the computer kept power on. After that I thought the RAM data are so volatile that forensic investigators really don’t care about when do investigation. However, today professor mentioned about RAM evidence in class, so I thought it can be important in some cases even if it has volatile properties. And then I found this paper explaining about the significance of volatile data.

The necessity for Expert System in various fields stems from the surplus of data we find ourselves with, in this era. Using Expert Systems on manually tiring, repeated work can save public and private organizations time and human resources. This is equally as true for digital investigations.

The weight placed on such evidence how ever good the job done is, can be thrown away if the defence can prove a broken chain of custody. Therefore, it is imperative for a digital forensic practitioner to pay attention to how chain of custody can impact on his job.
