Computer forensics and evidence management are the most important topic and very important aspect when we talk about computer crimes. Ethical hacking and intrusion management used to protect the system, but if the incident happened, then you need to investigate it. Here computer forensic comes. We have also created a free computer forensics training course for everyone to get the basic understanding of the process, methodology and tools used while conducting a digital investigation.
Anyway, in this story, you will find the basic introduction of the top 3 forensic tools.
The Sleuthkit & Autopsy
www.sleuthkit.org
The Sleuthkit is a free open source suite of forensic utilities that has a GUI called Autopsy. This tool suite has strong support for Linux file systems and can be used to examine the full details of inodes and other data structures. The Sleuthkit has a plugin framework that supports automated processing. The Autopsy GUI for The Sleuthkit is shown here with a Linux file system:
