To a great extent traffic travels on the network every minute a day. As the traffic increases much of signatures get defined. Some traffic falls into category of 'Obvious' and another into 'Obscure'. Obvious is what network expects and healthily transmits but obscure will be causing harm to network. When it comes to distinguishing between obvious and obscure traffic, a lot of packets has to pass through an intrusion prevention system and on the basis of that whatever packets moves towards right destination carrying destined information and the packets causing harm to the network can be distinguished. So wise false positives and false negatives happens to every IPSs.
