Computer Forensic Analysis Modes
In the world of computer forensics, an examiner will be performing either a live analysis or a dead analysis on a computer system, depending on the situation. Below are their descriptions.
A live analysis occurs when the suspect system is being analyzed while it is running. In this case, Autopsy and The Sleuth Kit are run from a CD in an untrusted environment. This is frequently used during incident response while the incident is being confirmed. After it is confirmed, the system can be acquired and a dead analysis performed.
A dead analysis occurs when a dedicated analysis system is used to examine the data from a suspect system. In this case, Autopsy and The Sleuth Kit are run in a trusted environment, typically in a lab. Autopsy and TSK support raw, Expert Witness, and AFF file formats.
