02 — Observing exposed services
Cowrie Honeypot
“How quickly will someone find an exposed machine?”
The idea
I wanted a better understanding of the background noise that reaches an exposed service, rather than only reading about it.
The build
I deployed Cowrie on a VPS and used it as a safe way to observe interactions with a simulated SSH service and collect logs for investigation.
Problems & investigation
- Reviewing patterns in connection and command activity
- Separating automated behaviour from more general probing
- Learning how exposed services are discovered
What I learned
- Internet-facing services attract attention quickly
- Logs become more useful when reviewed with a clear question
- Defensive security starts with understanding what is visible
What's next
Continue investigating the collected activity and improve how the observations are organised for review.
