Usage of Netflow in Security and Monitoring of Computer Networks
Management of a network is a challenging task without accurate traffic statistics. Through this paper the security benefits of implementing a Netflow based analysis system and then a novel open source application useful in Netflow analysis and management of flow records is proposed. Netflow data provides important information about network conversations and behavior. Netflow statistics are generated by Cisco and Juniper routers and switches, as well as server software Netflow probes. Netflow data provides enough information to serve the needs of several different applications such as billing, network planning and most importantly traffic engineering, which the authors specifically analyze to assess the state of the network.
