The acquisition of persistent memory has formed the basis of the main evidence involved in civil and criminal cases since the inception of digital forensics, however, more often, due to the size of storage capacity available, volatile memory can also contain significant evidence and assist in providing evidence of the most recent activity conducted by the user. ShellBags is a popular Windows forensics artifact used to identify the existence of directories on local, network, and removable storage devices. An examiner needs to get to the cache and register immediately and extract that evidence before it is lost.

Booz Allen introduces MOTIF, the largest public dataset of malware with ground truth family labels. Volatile data could provide evidence of system or Internet activity which may assist in providing evidence of illegal activity or, for example, whether files or an external device was being accessed on that date, which may help to provide evidence in cases involving data theft. This certification from the International Association of Computer Investigative Specialists (IACIS) is available to people in the digital forensics field who display a sophisticated understanding of principles like data recovery, computer skills, examination preparation and file technology. Common forensic activities include the capture, recording and analysis of events that occurred on a network in order to establish the source of cyberattacks. In addition, suspicious application activities like a browser using ports other than port 80, 443 or 8080 for communication are also found on the log files. Network forensics focuses on dynamic information and computer/disk forensics works with data at rest. Due to the dynamic nature of network data, prior arrangements are required to record and store network traffic.
