There is more than one Tripwire
Both are based on the same code, written by Gene Kim and Dr. Eugene Spafford at Purdue University in 1992, but Tripwire’s commercial products and Open Source Tripwire have followed different development roadmaps since they diverged in 1999.

The Open Source Tripwire project is found on Sourceforge.
