The only solution is packet capture and analysis to solve this issue. With the details provided by a packet-based solution, any specific transaction can be verified, like acknowledgements of credit card transactions, showing exactly where the transaction originated and removing any question as to the originator and their completion of the transaction.
NetFlow can provide a great deal of network visibility, along with some very detailed reporting, but there are times when only packet-based analysis will do. With packetbased network analysis, you get the most complete view of how your network and applications are performing. It provides both the overall level of network monitoring and recording that you get from flow-based solutions, while providing all the detail you need when you really have to dig in to solve a problem. So why deploy two systems when one will do just fine, 100 percent of the time?
