Final answer:
For filesystem-based timeline creation, Plaso (log2timeline) and The Sleuth Kit with Autopsy are two widely used tools that assist in forensic investigations by compiling comprehensive timelines from system files.
Step-by-step explanation:
Two tools commonly used for creating filesystem-based timelines include Plaso (log2timeline) and The Sleuth Kit (TSK) combined with Autopsy. Plaso is an advanced tool that extracts timestamps from various files found on a system and compiles them into a comprehensive timeline, which can be essential for forensic investigations. Similarly, The Sleuth Kit is a collection of command-line forensic tools that allow you to analyze disk images and recover data from them, while Autopsy serves as a graphical interface on top of TSK, providing a more user-friendly way to access the functions of TSK and aiding in the timeline creation process.
