“Tripwire is an Intrusion Detection System. This can be used to
alert users whenever their system is compromised. Tripwire detects
and reports changes in system files. It will alert you through
email whenever a change is detected. If the change is due to normal
system activity, you can instruct Tripwire not to report the change
to that file in future. If the change is not due to normal system
activity, then it is a clear indication that something is wrong and
you need to act immediately and fix the issue. Thus tripwire comes
very handy to maintain the integrity of the system.“There is lot of information on the web about Tripwire. Some

Fedora Box. Advanced users can refer to the web for relevant
information or they can contact appropriate mailing lists…”
