Why it matters

Each VOE question references these same notes. Reading them here gives students a zero-pressure chance to learn before they play.

Lectures stick to defensive workflows: log review, access control, forensic hygiene.

Coach's checklist

  • Know your visibility commands (logs, sockets, processes).
  • Recall exact firewall syntax (ports, protocols, line numbers).
  • Practice safe triage habits (hashing, archives, journalctl).
