Network traffic analysis can give rapid feedback, but at its fastest, it is only “ nearly live.” Security applications can’t detect threats until they have streams of data to work on. The information available at the Network Layer is insufficient to spot overall traffic patterns and it misses malicious traffic that is intentionally spread across numerous packets or combines actions from different sources. So, NTAs can be said to operate at the Application Layer and not the Network Layer.Īnalyzing at the Application Layer gives the NTA tool a better overview of network activity. Packet headers are the main source of information for analysis, but traffic analyzers wait until a series of packets have been captured and stored. They can also consolidate that source material to discover unusual user behavior.Īlthough the network offers live source data, network traffic analysis tools rarely operate in real-time. At the other end of the scale, you will find complex systems that sample traffic from several points of the network simultaneously. That information then needs to be processed to gain meaningful insights into traffic patterns.
What to look for in a network traffic analysis toolĪt the simpler end of the market, you will find packet sniffers that copy passing traffic into files.

The diversity of traffic analysis purposes can be seen in the list of the best network traffic analysis tools: More recently, network traffic analysis has expanded to include deep packet inspection used by firewalls and traffic anomaly analysis used by intrusion detection systems. Historically, this strategy was intended to investigate the sources of all traffic and volumes of throughput for the sake of capacity analysis.
Network traffic analysis involves examining packets passing along a network.
