"Like all good ideas, the underlying concept is simple, while the implementation is elegant. For an intruder to leave a Trojan that is not immediately apparent, he or she needs to modify existing files; for a malcontent employee to cause damage, he or she needs to change or destroy files. GFI LANguard S.I.M. runs as a service and monitors important system files. If anything happens to them, it immediately sends an alert to an administrator."
Well, there you have it... a rather handy system monitoring utility that doesn't cost you a nickel. You can completely customize the scanning to include or exclude any files you choose so you're keenly aware of when something changes unexpectedly. You can even add custom scan jobs to run at the times you specify so you can watch certain things more closely than others. For example, I might have the service checking the C:\Windows directory every 24 hours, while looking over the web server directory every hour. Quite a handy freebie!
