Easier development of embedded Linux applications with ELinOS

For many years, embedded Linux systems have been used predominantly in networked environments. These systems worked well for a long time - true to the motto "Never touch a running system". However, this inevitably leads to security problems and is accompanied by the fact that, according to the latest Cyber Security Report by Allensbach and Deloitte, managers see a growing threat situation in their IT infrastructures.

Echtzeit-Leistung für Multi-Core-Designs

In Multi-Core-Systemen ist kaum vorhersagbar, wie sich die Kerne gegenseitig beeinflussen, wenn auf gemeinsame Ressourcen zugegriffen wird. Bisher wurde sicherheitshalber das gesamte System gesperrt, solange kritische Codesegmente ausgeführt werden. Aber das muss nicht sein, denn das geht auf Kosten des Echtzeitverhaltens.

certMILS eases Security Certification of Railway Systems

In the latest issue of Global Railway Review, Dr. Sergey Tverdyshev (Director of Research & Technology at SYSGO) talks about security certifications of railway systems considering the MILS concept. He is the technical leader of the certMILS project – certMILS aims to protect critical infrastructure against cyber-attacks by compositional security certification to deliver a certified Multiple Independent Levels of Security (MILS) platform. But how can this be applied to railway systems?

Separation Kernel as a Basis for certifiable Applications and Systems

Functional security and cybersecurity are among the most important issues in the development of modern vehicles, and the certification of individual systems will become increasingly important in the future. Developers must therefore increasingly work according to the "Safety & Security by Design" principle. Real-time operating systems based on a separation kernel enable new approaches.

Separation Kernel als Basis für zertifizierbare Anwendungen und Systeme

Funktionale Sicherheit und Cybersecurity zählen zu den wichtigsten Themen bei der Entwicklung moderner Fahrzeuge, und der Zertifizierung einzelner Systeme wird in Zukunft eine immer höhere Bedeutung zukommen. Entwickler müssen daher zunehmend nach dem Prinzip "Safety & Security by Design" arbeiten. Echtzeitbetriebssysteme auf Basis eines Separation Kernels ermöglichen dabei neue Ansätze.

Cyber Security as a Design Objective

Increasing digitalisation presents the armed forces with a whole host of new challenges. Digitalised vehicles and weapon systems are potentially vulnerable to cyber attacks ‒ and not just when they are connected to the Internet. As demonstrated by the Stuxnet computer worm in the attacks on the Iranian nuclear programme, even systems and networks that are supposedly isolated are at risk. Social engineering allows malware to infiltrate such systems even without a direct network connection.

Cybersicherheit als Entwicklungsziel

Die zunehmende Digitalisierung bringt für die Streitkräfte eine ganze Reihe neuer Herausforderungen mit sich. Digitalisierte Fahrzeuge und Waffensysteme sind potentiell anfällig für Hackerangriffe, und das nicht nur, wenn sie tatsächlich mit dem Internet verbunden sind. Wie der Computerwurm Stuxnet bei den Angriffen auf das iranische Atomprogramm gezeigt hat, sind auch vermeintlich isolierte Systeme und Netzwerke gefährdet. Über Social Engineering lässt Schadsoftware sich auch ohne unmittelbare Netzwerkverbindung in solche Systeme einschleusen.

Security Certification of IoT Devices with a Component-based Software Design

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.

Uniform Hardware Platforms for all Car Features

The cost-effective and safe implementation of assistance systems and autonomous cars requires a new approach to development of the control components. The objective is to integrate diverse applications on one hardware platform, but - for safety reasons - to be able to continue operating them fully independently.

Entwicklung und Zertifizierung deutlich vereinfacht

Fahrerassistenzsysteme und autonomes Fahren sind neben der Elektromobilität derzeit die wichtigsten Schwerpunkte in der Automobilentwicklung. Schon heute sind viele Funktionen in Automobilen vollständig oder teilweise automatisiert; Fahrerassistenzsysteme wie Abstandswarner, Rückfahrkameras oder Einparkhilfen finden Zugang in die Serienproduktion selbst kleiner und mittlerer Fahrzeuge. Komplett autonom fahrende PKW, Busse und auch LKW sind auf öffentlichen Straßen im Testbetrieb; erste Serienfahrzeuge können sich zumindest teilautonom bewegen.

How to address Certification for Multi-Core based IMA Plattforms

In modern aircrafts, more and more functions traditionally implemented as Line Replaceable Units (LRUs) will be hosted by Integrated Modular Avionics (IMA) modules. At the same time new aircraft programs will require new safety functions, information services and comfort features which will also increase the demand for processing performance of IMA modules.

A Modular Train Control System through the Use of certified COTS HW/SW and qualified Tools

The European Rail Traffic Management System (ERTMS) forms the basis for standardization in relation to train control systems (ETCS), command control and safety technology, and Integrated Electronic Control Centres (IECC) in Europe [ETC16]. The previous HW/SW systems in these fields followed a monolithic integration approach applied by the individual manufacturers. This harbours problems relating to the compatibility of the systems of the various manufacturers, creates dependencies and reduces the diversity of solutions, by means of which safety-critical HW and SW defects find appropriate potential for their dissemination [HAS16, HAS08].
