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].
  
== Format ==
+
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 basic format is a list, consisting of a (shell item) entry size value (field) and entry data.
+
== Supported Formats ==
 +
The information below is based of version 1.1.0
  
There are multiple types of entries to specify different parts of the "path":
+
=== Storage Media Image File Formats ===
* volume
+
Storage Medis Image File Format support is provided by [[dfvfs]].
* network share
+
* file and directory
+
* URI
+
  
Some shell item entries contain date and time values which can be used in [[Timeline Analysis]].
