Know Your Tools: use Picviz to find attacks

We are very excited to announce the publication of our first paper in the new Know Your Tools paper series: “KYT: use Picviz to find attacks” authored by Sebastien Tricaud from the French Chapter and Victor Amaducci from the University of Campinas.

The paper can be downloaded at Know Your Tools: use Picviz to find attacks.

Paper Abstract
Picviz is a parallel coordinates plotter which enables easy scripting from various input (tcpdump, syslog, iptables logs, apache logs, etc..) to visualize data and discover interesting aspects of that data quickly. Picviz uncovers previously hidden data that is difficult to identify with traditional analysis methods.

In the first paper of our new Know Your Tools series, Sebastien Tricaud from the French Honeynet Project Chapter and Victor Amaducci from the University of Campinas, focus on Picviz. After a brief overview on parallel coordinates, Picviz architecture, and installation procedure, three real-world examples are presented that illustrate how to identify attacks from large amounts of data: Picviz is used to analyze SSH logs, Apache access logs and network traffic. With these examples, it is demonstrated how Picviz can find attacks that previously have been hidden.

Recent additions to Picviz GUI have been made by Victor Amaducci under the mentorship of Sebastien Tricaud as part of the Google Summer of Code program 2009. The most recent version of Picviz is freely available for download from its project site at http://www.wallinfire.net/picviz and support can be sought from the Picviz mailing list at http://www.wallinfire.net/cgi-bin/mailman/listinfo/picviz..

Picviz 0.5 out

The new release 0.5 of Picviz is out. This version comes with real-time mode enabled (and adds the libevent dependency) among other things, such as new properties and variables.

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.
