Create results directory¶

mkdir -p "$RESULTS_DIR"

Process each target¶

while IFS= read -r target; do echo "Processing $target..."

snap \
    --config "$CONFIG_FILE" \
    --output json \
    --output-file "$RESULTS_DIR/$\\\\{target\\\\}.json" \
    run "$target"

done < "$TARGETS_FILE"

Generate summary report¶

snap report summary \ --input "$RESULTS_DIR/*.json" \ --output "$RESULTS_DIR/summary.html" ```_

Verwenden Sie die Versionssteuerung für Konfigurationen
Überwachung und Alarmierung von kritischen Metriken
Implementierung einer korrekten Fehlerbehandlung
Automatisierung für repetitive Aufgaben verwenden
Regelmäßige Sicherheitsaudits und Updates
Plan zur Katastrophenrückgewinnung

Entwicklung¶

Befolgen Sie Kodierungsstandards und Konventionen
Vollständige Tests schreiben
Verwenden Sie die kontinuierliche Integration / Bereitstellung
Durchführung der richtigen Protokollierung und Überwachung
Dokumente APIs und Schnittstellen
Verwenden Sie die Versionskontrolle effektiv
Prüfcode regelmäßig
Rückwärtskompatibilität sichern
