No, the functionality of an IDS is to tell you that somebody just pointed the exploit at you and (hopefully) failed to get in. Consider the unexplained theft of valuables from a bank vault. The surveillance camera may not show how they actually got it, but when you're looking for suspects, a good place to start would be those 3 guys who spent a half hour trying to do the lock on the door earlier that night..... > Useless.
