Collection of State Information in Live Digital Forensics All the information collected will be compressed and protected by a password. Memory forensics is the process of capturing the running memory of a device and then analyzing the captured output for evidence of malicious software. and move on to the next phase in the investigation. The volatile data of a victim computer usually contains significant information that helps us determine the "who," "how," and possibly "why" of the incident. This volatile data is not permanent this is temporary and this data can be lost if the power is lost i.e., when computer looses its connection. To avoid this problem of storing volatile data on a computer we need to charge continuously so that the data isnt lost. that systems, networks, and applications are sufficiently secure. (Grance, T., Kent, K., & preparationnot only establishing an incident response capability so that the organization is ready to respond to incidents, but also preventing incidents by ensuring. be at some point), the first and arguably most useful thing for a forensic investigator It will showcase the services used by each task.
