What is the method used to intercept and log network traffic called?

The method used to intercept and log network traffic is commonly referred to as packet capture. This process involves capturing data packets as they traverse a network, allowing an administrator or security professional to analyze the information contained within those packets. Packet capture tools can be employed to examine traffic for a variety of purposes, such as troubleshooting network issues, monitoring performance, and identifying potential security threats.

Packet capture tools are instrumental in providing insights into the types of data being transmitted, including source and destination addresses, protocols in use, and any payload data. The captured packets can then be examined in-depth, using software that can decode and analyze the data for further insights.

While other methods like network sniffing can refer to similar processes, they are often considered more focused on the act of monitoring traffic, including capturing, rather than the detailed logging aspect that packet capture emphasizes. So, while "network sniffing" and "traffic monitoring" are relevant, they may not encompass the full breadth of what packet capture entails in data analysis.
