If I turn the paranoid mode up a notch or two here.. What is to stop someone from mounting another filesystem over the top of your tripwire database and crontab entries. Replace the mount and df commands to not show the new mount point. Now you continue to believe that you are a happy camper, all safe and secure. You really need to do a seperation of the checkee from the checkor. If someone has root access on the machine, the could basicly do anything that is needed to cover their tracks. Eiji Hirai writes:

The best thing to do is to run tripwire from a read-only device (like a floppy) from which you can check the integrity of any number of files, like crontab. ftp://coast.cs.purdue.edu/pub/COAST/Tripwire -- Eiji Hirai The NetMarket Company eiji () netmarket com
