There are two main techniques used in Traffic Analysis:
| Flow Analysis | Packet Analysis |
| Collecting data/evidence from the networking devices. This type of analysis aims to provide statistical results through the data summary without applying in-depth packet-level investigation.Advantage: Easy to collect and analyse.Challenge: Doesn’t provide full packet details to get the root cause of a case. | Collecting all available network data. Applying in-depth packet-level investigation (often called Deep Packet Inspection (DPI) ) to detect and block anomalous and malicious packets.Advantage: Provides full packet details to get the root cause of a case.Challenge: Requires time and skillset to analyse. |
Benefits of the Traffic Analysis:
- Provides full network visibility.
- Helps comprehensive baselining for asset tracking.
- Helps to detect/respond to anomalies and threats.
