41 Cybersicherheit von Embedded Systems, OT und IoT /invite Thomas Weber, CyberDanube

Eingebettete Geräte („embedded systems“) sind ein fester Bestandteil unseres täglichen Lebens. Diese Geräte, die von Smart Metern bis hin zu industriellen Steuerungssystemen reichen, sind darauf ausgelegt, bestimmte Aufgaben auszuführen und werden in der Regel mit begrenzten Ressourcen gebaut. Natürlich haben „embedded systems“ oder auch OT/operational technology IT-Sicherheitsprobleme. Zusammen mit Thomas Weber spreche ich über die Cyber-Sicherheitsimplikationen dieser zahlreichen Geräte. Wir gehen darauf ein, wo „embedded systems“ überall drin stecken, welche Verwundbarkeiten sie haben und wie man ihre Sicherheit verbessern kann. Wir veranschaulichen das am Beispiel der Smart Meter Diskussion zur intelligenten Steuerung des Stromnetzes. Zum Schluss sprechen wir auch noch über aktuelle Entwicklungen in der EU, wie der EU Cyber Resilience Act, der auch an den IT-Sicherheitsanforderungen von „embedded systems“ Verbesserungen einführt.
