Routing evidence refers to technical data that documents the path internet traffic takes as it moves between different networks. This information helps identify the sequence of routers, switches, and service providers involved in delivering data from a sender to a recipient. In cybersecurity and digital investigations, routing evidence is crucial for tracing the origin and route of network communications, detecting malicious activity, and attributing cyber incidents. By analyzing routing evidence, experts can better understand how data flows across the internet and identify potential vulnerabilities or unauthorized access points.
