Title: RE: TripWire

Jesus-

I will have to look into your second question, but the first is quite simple and actually gets to the heart of what Tripwire is about:

Hacking for Girlies needed to know nothing more than what any system administrator knows about Tripwire.. you must protect your database.  With the "free" open-source version this means keeping it and your policy file on read-only or removable media.  The whole concept of Tripwire is that you take a "snapshot" database, protect that database, and then check against it for changes.  Very simple, very effective.  If you were to leave the database on the system, and someone went root, they would have all the rights necessary to alter the database to match their changes (it's just a text file!).  This is what Route66 did.  No exploit, just user error.  You can imagine all of us here yelling at that article when they made that claim.

They presumably did this because they wanted to run Tripwire as a cron job and had too big of database to fit onto a floppy or other readily available read-only media.  There are a number of ways to accomplish this, though without being overly commercial in this forum I will say that this is one major part of why there is a market for the commercial version of Tripwire: signed and obfuscated database and policy file among other enhancements.

I wouldn't consider any security installation safe without a Tripwire layer.. but hey, I work here! ;-)
