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.
