Abstract:


This paper presents the main concepts of computer forensics and describes the techniques and tools used in digital forensics. The application of the concepts, tools, and techniques was performed by an experimental case study (e.g., File sharing with pedophile content.). The proposed case study was carried out in a Linux system and includes the following steps: computer tapping, analysis of storage devices, chain of custody, steganalysis, using the NuDetective tool, and the preparation of the forensic report. Thus, it is intended to show a full criminal investigation so that end users can, with some easy, reproduce the steps described in this work.
