Design and Implementation of A Digital Forensic System Based On Open Source

Abstract

As the popularity of the internet continues growing, not only change our life, but also change the way of crime. Number of crime by computer as tools, place or target, cases of such offenders increases these days, fact to the crime of computer case traditional investigators have been unable to complete the admissibility of evidence. To solve this problem, we must collect the evidence by digital forensics tools and analysis the digital data, or recover the damaged data. In this research, we integrate several famous open source digital forensics tools and we setup the whole system into a Live DVD/USB based on Xubuntu to become a portable forensic system. Additionally, To avoid the data loss due to the shutdown of machines, we use the Live-analysis to collect volatile information. We use the MD5 and SHA-1 code to identity the file before the final report and ensure the reliability of forensic evidence on court.
