Port réseau

Outcome: Complete the task with Port réseau (Network Port). User context: Un frontend utilise le port 4321 et appelle une API sur le 8000. Le proxy public expose uniquement le HTTPS sur le 443. Technical concept or control: Port réseau (Network Port). Why it fits: Définissez clairement les ports pour les services locaux, les conteneurs, les pare-feu, les contrôles de santé et les proxies inverses. Do not use it when: N'exposez pas les ports de base de données ou d'administration publiquement. Séparez les ports des conteneurs des ports publiés sur l'hôte. Engineering requirements: Define inputs, outputs, contracts, and rules that must always hold. Set authorization and input checks. Define failures, timeouts, retries, one-time effects, data moves, and compatibility limits. Operations: Add useful signals and logs that hide sensitive data. Set capacity limits and write an operator guide. Test recovery and rollback. Acceptance criteria: Contract and failure-path tests pass. Data and authorization rules still hold during retries and partial failures. Check performance limits, monitoring, recovery, and rollback. Evidence and limits (evidence boundary): La norme couvre uniquement le champ d'application énuméré. Elle ne choisit ni le style visuel, ni la décision de produit, ni l'exemple de Vibulary. Unknowns to confirm: Where the code runs, data stores, traffic shape, consistency needs, and the security boundary. Also confirm the compatibility period, service goals, and rollback limits.
