'''UNIX''' is a general-purpose multi-user operating system developed mostly by Ken Thompson and Dennis Ritchie during 1969 at Bell Labs. About one year later during the early 1970s UNIX was unveiled to the general public. The original design as it is today was to create a stable, secure, and powerful operating system that is portable to many different hardware platforms. Today UNIX has evolved into three main categories which all flavors of UNIX derive from: BSD (Berkley Software Development), System V Release 7, and hybrid. Some of the most poplar flavors of UNIX are: [http://www.ibm.com/servers/aix/overview IBM’s AIX], [http://www.sun.com Sun Microsystems Solaris], [http://www.sgi.com SGI’s IRIX], [http://http://www.linux.org Linux], [http://www.OpenBSD.org OpenBSD], and [http://www.FreeBSD.org FreeBSD].

Revision as of 21:31, 20 April 2006

Although not strictly for forensic purposes, visualization tools such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.

Open Source Visualization Toolkits

The Visualization Toolkit
C++ multi-platform with interfaces available for Tcl/Tk, Java and Python. Professional support provided by Kitware.
Graphviz
Originally developed by the AT&T Information Visualization Gorup, designed for drawing connected graphs of nodes and edges. Neato is a similar system but does layout based on a spring model. Can produce output as PostScript, PNG, GIF, or as an annotated graph file with the locations of all of the objects---ideal for drawing in a GUI. Runs from the command line on Unix, Windows and Mac, although there is also a MacOS GUI version.
OpenDX
Based on IBM's Visualization Data Explorer, runs on Unix/X11/Motif.
VisAD
A Java component library for interactive and collaborative visualization.
