Échouer sainement
Assainir et valider les entrées de configuration, et répondre aux entrées invraisemblables en continuant à fonctionner dans l'état précédent et enalertant sur la réception d'une mauvaise entrée. Les données erronées tombent souvent dans l'une de ces catégories :
- Données incorrectes
-
Valide à la fois la syntaxe et, si possible, la sémantique. Surveille les données vides et les données partielles ou tronquées (par exemple, alerte si la configuration est N% plus petite que la version précédente).
- Données retardées
-
Cela peut invalider les données actuelles en raison des dépassements de délai. Alerte bien avant l'expiration prévue des données.
Échouer d'une manière qui préserve la fonction, peut-être au prix d'être trop permissif ou trop simpliste. Nous avons constaté qu'il est généralement plus sûr pour les systèmes de continuer à fonctionner avec leur configuration précédente et d'attendre l'approbation d'un humain avant d'utiliser les nouvelles données, peut-être invalides.
