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.

Plaso is a Python-based rewrite of the Perl-based log2timeline initially created by Kristinn Gudjonsson and extended by the contribution of various others.

Plaso builds upon the SleuthKit, pytsk, libyal, dfvfs and various other projects.

This section contains several tools that can help in analyzing plaso's timeline output:

  • 4n6time, formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review. This tool appears to be abandoned.
  • Timesketch a collaborative forensic timeline analysis.
