Summary
- Define the interface, protocol, time window and incident question before collecting traffic.
- Restrict payload access, preserve capture integrity and delete material when the investigation closes.
Microsoft Network Monitor belongs to an earlier generation of packet analysis, but the operating lesson remains current. A trace may expose credentials, personal content and unrelated sessions while still missing traffic on another path. Operators should obtain authority, synchronise clocks, capture the smallest useful scope and record filters and hashes. The next useful evidence is a reproducible finding that links packets to a symptom and can be reviewed without opening the whole dataset. Observability is valuable when collection answers a defined question rather than becoming permanent surveillance.
