Troubleshooting As A Discipline
When a technique fails, name the failure precisely.
Classify the failure
- Technique failed vs tool failed vs transport failed.
- Authentication failed vs authorization denied.
- Configuration wrong vs assumption wrong.
- Environment mismatch (arch, version, patch).
- Detection / security control blocked it.
Drills
- Break your own lab intentionally (DNS, time skew, firewall, cert trust) and diagnose from symptoms.
- Reproduce the failure in a smaller experiment before searching.
- Rule: read the actual error text out loud before Googling it.
