What is an artifact in the context of digital forensics?

In the context of digital forensics, an artifact refers to any data or residual traces left on a digital device that can provide insights into user activity. Artifacts can include files, log entries, metadata, registry entries, and other digital remnants that result from a user's interactions with a system. These artifacts are critical for forensic investigations as they can help build a timeline of events, reveal user behavior, and support or dispute claims related to digital activities.

The role of artifacts in digital forensics is paramount because they serve as evidence in instances of cybercrime, data breaches, and various information security incidents. Investigators analyze these artifacts to piece together the actions of users and the events that transpired during a particular incident, thereby assisting in reconstructing what happened.

Other options do not accurately capture the definition of artifacts in digital forensics. Data lost during system failure is more about loss and recovery, not the traces left behind. Scientific data from experiments and historical documents about technology are not directly related to the realm of digital forensics, which focuses specifically on evidence derived from digital devices and data.
