Mit der Firewall von Plesk lassen sich Server vor Angriffen schützen, indem der Zugriff auf die Dienste von Plesk (wie Webhosting, E-Mail-Hosting und FTP) kontrolliert wird. Sie können die Firewall-Konfiguration mithilfe von Regeln und Richtlinien steuern. Schutzoptionen der Firewall:

• Server mit Standardregeln und -richtlinien schützen
• Standardregeln und -richtlinien anpassen oder eigene Regeln und Richtlinien erstellen, um für einen erweiterten Schutz zu sorgen
• Länderbasierte Sperre, mit der der Zugriff aus bestimmten Ländern über ISO 3166-Ländercodes eingeschränkt wird
• Firewall-Konfiguration über die Benutzeroberfläche oder die Befehlszeilenschnittstelle exportieren/importieren, um die Duplizierung von Firewall-Konfigurationen für Plesk für Linux-Server zu vereinfachen

Diese Funktionen ermöglichen es Benutzern, robuste Netzwerksicherheitsmaßnahmen zu treffen und die Firewall-Verwaltung in Plesk zu optimieren.
