Viele Jahre lang wurden Embedded Linux-Systeme überwiegend in vernetzten Umgebungen eingesetzt. Diese Systeme haben lange Zeit gut funktioniert - getreu dem Motto "Never touch a running system". Dies führt jedoch unweigerlich zu Sicherheitsproblemen und geht damit einher, dass laut dem aktuellen Cyber Security Report [1] von Allensbach und Deloitte die Verantwortlichen eine wachsende Bedrohungslage in ihren IT-Infrastrukturen sehen.

Eingebettete Systeme sind in vielen elektronischen Geräten…

Hybrid system-on-chips increasingly integrate heterogeneous processors. However, developers see them as one component that they want to develop as integrated as possible. A homogeneous RTOS and hypervisor ecosystem for both MPU- and MMU-supported processors provides the critical convenience gain.

When developing embedded systems that are to be real-time capable, one of the first and most important questions is whether the applications should run under a real-time operating system (RTOS) or whether a bare-metal solution should be developed. Bare-metal programming is generally understood to mean that an application is written directly on the hardware without using an external programming interface, i.e. an operating system. Applications access here directly hardware registers of…

The continuing technological advancement that is enabling decreasing costs and greater compactness of devices make it possible to connect and control more physical elements in the industrial environment today. This is enabling industrial engineers to monitor processes with greater accuracy and drive OEE (Overall Equipment Effectiveness). At the same time separate operational technology (OT) systems are merging with enterprise IT infrastructure. However, this greater connectivity also brings more…

Different types of IoT applications are subject to different security standards. Whether you want to meet the requirements of the Common Criteria for Information Technology Security (ISO 15408), IEC 62443 for Industrial Control Systems, EDSA (Embedded Device Security Analysis) or J3061 in the automotive sector: We will show you how you can quickly meet all necessary requirements with a component-based software design.

In many applications in the railways, aircraft or automotive industry the interaction between safety and security is of particular importance, since there are many dependencies between them and they can therefore no longer be considered separately.
