mkdir -p "$RESULTS_DIR"

Process each target¶

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

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

done < "$TARGETS_FILE"

Generate summary report¶

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

Überprüfen Sie immer Prüfsummen beim Herunterladen von Binaries
Verwenden Sie starke Authentifizierungsmethoden (API-Tasten, Zertifikate)
Regelmäßig auf die neueste Version aktualisieren
Prinzip der Mindestberechtigung
Aktivieren Sie Auditprotokoll für Compliance
Verwenden Sie verschlüsselte Verbindungen, wenn möglich
Alle Eingänge und Konfigurationen validieren
Implementierung der richtigen Zugangskontrollen

Performance¶

Verwenden Sie geeignete Ressourcengrenzen für Ihre Umwelt

Optimieren Sie die Konfiguration für Ihren Anwendungsfall
Verwenden Sie parallele Verarbeitung, wenn nützlich
Durchführung richtiger Cache-Strategien
Regelmäßige Wartung und Reinigung
Profilleistung Engpässe
Verwenden Sie effiziente Algorithmen und Datenstrukturen

Operational¶

umfassende Dokumentation
Implementierung von richtigen Backup-Strategien
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
