'''The Sleuth Kit''' ('''TSK''') is a collection of [[UNIX]]-based command line tools that allow you to investigate a computer. The current focus of the tools is the file and volume systems and TSK supports many [[file system | file systems]] (see below).
+
Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating [http://blog.kiddaland.net/2013/02/targeted-timelines-part-i.html targeted timelines].
  
[[Autopsy]] is a frontend for TSK which allows browser-based access to the TSK tools.
+
The Plaso project site also provides [[4n6time]], formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by [[David Nides]].

The Sleuth Kit is arranged in layers. There is a ''data layer'' which is concerned with how information is stored on a disk and a ''metadata layer'' which is considered with information such as [[inode]]s and [[directory|directories]]. The commands that deal with the data layer are prefixed with the letter ''d'', which the commands that deal with the metadata layer are prefixed with the letter ''i''.

Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating targeted timelines.

The Plaso project site also provides 4n6time, formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by David Nides.
