Netzwerk-Security
Die operative Netzwerksicherheit ist – unabhängig von der Größe oder dem Angebot – das Herzstück eines funktionalen, produktiven Unternehmens. Netzwerk-Security ist ein breit gefächerter Schutzschirm und umfasst eine Vielzahl von Geräten, Prozessen und Technologien. Grundsätzlich besteht die Netzwerk-Security aus Konfigurationen und Regeln, die in den Geräten und Systemen Ihres Netzwerks implementiert werden, um ein ungesichertes Netzwerk zu sichern. Diese Regeln sorgen für Integrität, Datenschutz und die Einsatzbereitschaft Ihres Netzwerks und decken sowohl die Hard- als auch die Software ab, die Ihr Netzwerk am Laufen halten. Sicherheitsmaßnahmen können auf einzelne Geräte oder Komponentengruppen mit denselben Schwachstellen ausgerichtet werden. Sie können sich auch entscheiden, wo Schutzmaßnahmen eingreifen sollen.
