To capture, transmit and analyze NetFlow data the following NetFlow enabled components must be in place: This flow data must be captured from the network traffic, converted to a standard NetFlow record format, exported to a collector for aggregation, and then analyzed by the proper application to provide information useful in the analysis, planning and management of the network. This way, it actually covers the most critical threats that network face nowadays, such as advanced persistent threats, inside threats, and even employee abuse, unauthorized access and data leak cases.NetFlow as a protocol provides a means of collecting flow data from a network device and forwarding that data to a collector. And, you also have a historic data archive for later investigation whenever deemed necessary.
Further analysis of SIEM events can be explored thanks to NetFlow data. Unlike signature-based anti-viruses, facing known threats, this concept of not-preventing but quick-reacting is necessary for rising zero-day attacks. It compliments firewalls, centered on end points of the network, by providing inside view of the network. In general, NetFlow Analyzer software is an essential part of any security infrastructure for detecting anomalies in the network and troubleshooting threat incidents. NetFlow version 9 is the latest version, created to support advanced technologies such as MPLS, IPv6, Multicast, VLANs, etc. Version 5 is commonly used on most Cisco NetFlow enabled devices. There are numerous NetFlow protocol versions, most important of which are versions 5 and 9. NetFlow Analyzer performs all of these functions. It can then be reviewed in a more user-friendly form. This data is exported to a server, where it is collected, processed, aggregated and archived. NetFlow is a network protocol, developed by Cisco Systems, used for exporting collected IP flow traffic.
