[3], Various types of techniques are used to recover evidence, usually involving some form of keyword searching within the acquired image file, either to identify matches to relevant phrases or to filter out known file types. [3] Many forensic tools use hash signatures to identify notable files or to exclude known (benign) files; acquired data is hashed and compared to pre-compiled lists such as the Reference Data Set (RDS) from the National Software Reference Library[5], On most media types, including standard magnetic hard disks, once data has been securely deleted it can never be recovered.[9][10]. Forensics is closely related to incident response, … The duplication process is referred to as Imaging or Acquisition. Given the problems associated with imaging large drives, multiple networked computers, file servers that cannot be shut down and cloud resources new techniques have been developed that combine digital forensic acquisition and ediscovery processes.
