Network Protection Using NetFlow Data
Czudek, Marek ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
This thesis deals with the possibility of greater security of network based on NetFlow protocol. Specifically, the detecting network scans based on predefined rules to found this anomaly in the NetFlow data. Next part is the possibility of retrospective data analysis, thereby achieving more  accurate detection of attacks on the network. In this work designed application uses predetermined rules to detect the scans and then looks the flows towards the ports witch are protected by the application and than compares with detected scans. In this way, more accurate detection of attacks is achieved.
