Netwerkverkeersanalyse

Netwerkverkeersanalyse, or network traffic analysis, is the process of examining data packets that pass through a computer network. The goal is to understand network activity, identify potential security threats, and optimize network performance. By capturing and inspecting network traffic, administrators can gain insights into which applications are using the network, who is communicating with whom, and what types of data are being transferred.

This analysis typically involves specialized tools that can monitor traffic in real-time or analyze captured packet data. These tools can identify patterns, anomalies, and suspicious activities that might indicate a security breach, a misconfigured device, or a performance bottleneck. Common techniques include packet sniffing, protocol analysis, and flow analysis. Packet sniffing captures individual data packets, while protocol analysis decodes the information within those packets according to various network protocols like TCP/IP. Flow analysis aggregates traffic data into communication sessions, providing a higher-level view of network interactions.

The applications of network traffic analysis are broad. In cybersecurity, it is crucial for detecting malware, intrusions, denial-of-service attacks, and data exfiltration. For network administrators, it helps in troubleshooting connectivity issues, identifying bandwidth hogs, and ensuring efficient resource allocation. It can also be used for capacity planning and understanding user behavior on the network. Ultimately, network traffic analysis provides a vital window into the inner workings of a network, enabling informed decision-making for security and operational management.
