Lab — Logging Checklist for Your App
One checklist: must-log, alerts, privacy — app YOU own only.
Visual · logging_checklist_lab
Three columns: events, alerts, redaction. then log locally. Router admin STOP. No foreign SIEM. No secret dumps.
Opening
The lab is a logging/alerting checklist you could ship as a ticket — not a raid on someone else’s observability stack.
OWASP Top 10:2025 A09 is practiced as logging-lab.txt combining Lessons 1–3 for an app YOU own or a hypothetical-owned design. Must-log events, alert mapping, privacy redaction. ; Optionally curl DEMO to generate a request you log locally with fake-safe fields. Attack literacy stays; foreign SIEM access stays out. Next: quiz. Today: one locked artifact under cyberlium-lab.
1. Section A — must-log coverage
Tick authn success/fail, authz deny, admin changes, integrity fails. Note gaps.
2. Section B — alerts with owners
Map at least two events to alerts with threshold, owner, first actions. Fatigue policy.
3. Section C — privacy redaction
Never-log list and mask rules. Confirm no secrets in sample lines you paste (use fakes).
4. Evidence without exfiltration
If you show a log line, fabricate a realistic fake. Never paste production customer data. Optional curl of DEMO only if it is YOUR lab app — not the home router.
5. Wrong vs right
Same word “lab,” opposite ethics.
Wrong
Export real prod logs publicly. Page foreign on-call. Wipe school audit trails. Log passwords “as proof.” Hydra 192.168.0.1. nmap the LAN.
Right
Identify DEMO; router → STOP. logging-lab.txt A–C complete; fake samples only; chmod 600. Next: Quiz — Logging and Alerting.
6. Hands-on: DEMO curl + logging-lab.txt scaffold
Identify, optionally append a09-local-requests.log, fill every blank. Empty ethics fail.
Mission: logging-lab.txt (mode 600)
1) Optionally curl DEMO and append a fake-safe local log line.2) Complete A–C for owned or hypothetical-owned scope. Use only fake sample lines. 3) chmod 600 $HOME/cyberlium-lab/logging-lab.txt. No hydra. No nmap. No foreign SIEM.
Stuck? Ask Cyberlium AI Mentor
Ask how to invent a hypothetical-owned app checklist — not for access to a real SIEM. Try: "Hint only: minimum A/B/C fields; how to write a fake sample line; why 192.168.0.1 router login is OUT OF SCOPE; where the lab file lives?"
A09 lab is a shippable checklist on systems you own. Original Cyberlium — not official OWASP certification. Next — Quiz — Logging and Alerting.
Knowledge Check
APPLY: You lack prod access. Ethical lab?
Multiple choice
Knowledge Check
APPLY: True or False: Pasting a real customer password from logs into the lab file is good evidence.
True or False
Knowledge Check
APPLY: curl of http://192.168.0.1/ is router admin. Attach that host as the logging lab SIEM?
