Forensic computer science is the study of extracting information and data from computer networks and storage media and guaranteeing its accuracy. This is accomplished by identifying leads and evidence, evidence extraction and preservation, and fastidious documentation. Finally, it often involves expert testimony as to how specific data could have been created and how it was preserved.Forensic tools and methodologies can also be used to identify security weaknesses and to validate that security programs are working properly. Forensics benchmarking of systems prior to an incident also plays a critical role in incident response.
