Response-ready Cybersecurity Reaktionsbereit statt nur geschützt
Cybersecurity war lange Zeit vor allem eines: Prävention. Firewalls, Endpoint-Protection, E-Mail-Filter, Multi-Faktor-Authentifizierung die Strategie lautete, Angriffe möglichst früh zu stoppen, bevor sie Schaden anrichten. Das bleibt wichtig. Doch in der heutigen Bedrohungslage reicht dieser Ansatz allein nicht mehr aus. Die unbequeme Wahrheit lautet: Kein Schutzschild ist lückenlos. Und genau deshalb verschiebt sich der Fokus […]…
