Digital forensics involves preserving, identifying, analyzing, documenting, and presenting digital evidence in a way that maintains its integrity for use in legal cases. The process includes collecting relevant evidence from computers, networks, firewalls, databases, and mobile devices, analyzing it to determine what was accessed or stolen, and summarizing the findings to help trace the distribution of any stolen information. Popular digital forensics software tools aid in areas like network, firewall, and mobile device analysis and help determine the accuracy of investigation results.
