What is Picviz?
When considering log files for security, usual applications available today
either look for patterns using signature databases or use a behavioral
approach. In both cases, information can be missed. The problem becomes
bigger with systems receiving a massive amount of logs.
Parallel coordinates is an answer to display an infinity of events in multiple
dimensions. As security data are multivariate, parallel coordinates provides
a neat way to display and ease abnormal behaviors detection. Picviz implements
the use of parallel coordinates on acquired data, such as logs, to create a
parallel coordinates image.
Using this image, the analyst can use Picviz to improve the output image,
filter information and visually detect things.
