- KonferenzbeitragComparison of Aviation and Automotive Standards and Methods in Terms of Safety and Cybersecurity(Software Engineering 2022 Workshops, 2022) Akkus, Yusuf; Annighoefer, BjoernSafety and security methods from the aviation and automotive are compared. Current safety and security standards and regulations for both product development aspects like systems engineering, hardware/software development and their management are considered. Methods and processes are investigated. The main purpose is to figure out and understand the backgrounds and to characterize the similarities and differences. Moreover, potential opportunities for transferring methods from one industry to another are identified. Aviation has more systematic development and involves authorities throughout the complete development lifecycle. Huge volumes in automotive leads to quality-driven development. Assessment structure and process activities provide potential transfer. For security both areas face same challenges and standardization activities and development run parallel. Methods are being mainly taken over from safety and assessment is incorporated into the safety assessment lifecycle today. For certification process, authorities must take action in both areas since the security ecosystem includes a bigger scope like infrastructure, communication devices, traffic control.
- ZeitschriftenartikelISTQB® goes Automotive – CTFL®-CAST: Standardisierte Ausbildung für E/E-Tester(Softwaretechnik-Trends Band 36, Heft 3, 2015) Pohlmann, Horst; Dussa-Zieger, Klaudia; Bongard, RalfMittlerweile hat die Erfolgsstory ISTQB® mehr als 40.000 ISTQB® Certified Tester in Deutschland hervorgebracht, wobei weltweit mehr als 350.000 ISTQB® Certified Tester zu verzeichnen sind (Stand: Juli 2015). Das German Testing Board (www.germantesting-board.info), ein Zusammenschluss von Fachexperten aus Industrie, Trainingsanbietern und Hochschulen für das Testen von Software und Systemen, hat nun eine Initiative gestartet, neben den ISTQB® CORE-Lehrplänen branchen- und methodenspezifische Erweiterungen zu etablieren. Eine dieser Erweiterungen – CTFL1 ®-CAST – wurde speziell für die Automotive-Branche aufgesetzt und soll die besonderen Anforderungen des Testens von E/E Systemen in diesem Bereich abdecken. Zielsetzung der zertifizierten Ausbildung ist es, ein Grundverständnis über die Besonderheiten beim Test von Steuergeräte-Software im Automobil zu vermitteln. Tester sollen in die Lage versetzt werden, fundiert Teststrategien abzuleiten, normenkonforme Testverfahren auszuwählen und Tests durchzuführen, die gemäß der Sicherheitseinstufung des Steuergeräts relevant sind und auch einem Audit standhalten (siehe auch [3]). Der aktuelle CTFL®-CAST-Lehrplan [2] beinhaltet folgende Aspekte: Betrachtung der ISO 26262 und deren Implikationen für den Test unter Berücksichtigung unterschiedlicher ASIL-Stufen sowie Anforderungen an den Test aus Sicht von Automotive SPICE, z.B. in Bezug auf Traceability. Darüber hinaus werden unterschiedliche Testumgebungen besprochen (HIL, SIL, MIL, PIL) sowie die Einbindung der Testaktivitäten in den Produkt-Entstehungsprozess (PEP) im AutomotiveBereich. Ziel des Kurzvortrages ist es aufzuzeigen, wie eine solche standardisierte Ausbildung für E/ETester unter Beteiligung von Vertretern der 1-Tier-Supplier, OEMs, Seminaranbietern und Zertifizierungsstellen für die AutomotiveIndustrie seit 2014 systematisch entwickelt wird (siehe auch [1]). Des Weiteren soll für eine aktive Mitarbeit in der Arbeitsgruppe CTFL-CAST aufgerufen werden.
- KonferenzbeitragSoftware Traceability in the Automotive Domain: Challenges and Solutions(Software Engineering and Software Management 2019, 2019) Steghöfer, Jan-Philipp; Maro, Salome; Staron, MiroslawIn the automotive domain, the development of all safety-critical systems has to comply with safety standards such as ISO 26262. These standards require established traceability, the ability to relate artifacts created during development of a system, to ensure resulting systems are well-tested and therefore safe. Our study [MSS18] contrasts general traceability challenges and solutions with those specific to the automotive domain, and investigates how they manifest in practice. We combine a tertiary literature review to identify general challenges and solutions, a case study with an automotive supplier as validation for how challenges and solutions are experienced in practice, and a multi-vocal literature review to identify challenges and solutions specific to the automotive domain. We found 22 challenges and 16 unique solutions in the reviews. 17 challenges were identified in the case study; six remain unsolved. We discuss challenges and solutions from the perspectives of academia, tool vendors, consultants and users, and identify differences between scientific and “grey” literature. We discuss why challenges remain unsolved and propose solutions. Our findings indicate that there is a significant overlap between general traceability challenges and those in the automotive domain but that they are experienced differently.
- KonferenzbeitragTowards the Use of Controlled Natural Languages in Hazard Analysis and Risk Assessment(Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Chomicz, Paul; Müller-Lerwe, Armin; Wegner, Götz-Philipp; Busch, Rainer; Kowalewski, StefanNew safety-critical and software-controlled systems of automobiles have to be developed according to the functional safety standard ISO 26262. A hazard analysis and risk assessment has to be performed for such systems. The sub-activities of this analysis technique are defined by the standard, but informative definitions leave room for subjective variation, and documentation details are left to the car manufacturer. Usually, natural languages are used for the documentation, which are powerful and expressive but also complex and ambiguous. We propose the usage of controlled natural languages for the documentation of the results of the hazard analysis and risk assessment. In a first step, we developed a controlled natural language for the description of the hazardous events. The language reduces ambiguity and improves the consistency across hazard analyses and risk as- sessments.
- KonferenzbeitragUsing STPA in Compliance with ISO 26262 for Developing a Safe Architecture for Fully Automated Vehicles(Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Abdulkhaleq, Asim; Wagner, Stefan; Lammering, Daniel; Boehmert, Hagen; Blueher, PierreSafety has become of paramount importance in the development lifecycle of the modern automobile systems. However, the current automotive safety standard ISO 26262 does not specify clearly the methods for safety analysis. Different methods are recommended for this purpose. FTA (Fault Tree Analysis) and FMEA (Failure Mode and Effects Analysis) are used in the most recent ISO 26262 applications to identify component failures, errors and faults that lead to specific hazards (in the presence of faults). However, these methods are based on reliability theory, and they are not adequate to address new hazards caused by dysfunctional component interactions, software failure or human error. A holistic approach was developed called STPA (Systems-Theoretic Process Analysis) which addresses more types of hazards and treats safety as a dynamic control problem rather than an individual component failure. STPA also addresses types of hazardous causes in the absence of failure. Accordingly, there is a need for investigating hazard analysis techniques like STPA. In this paper, we present a concept on how to use STPA to extend the safety scope of ISO 26262 and support the Hazard Analysis and Risk Assessments (HARA) process. We applied the proposed concept to a current project of a fully automated vehicle at Continental. As a result, we identified 24 system- level accidents, 176 hazards, 27 unsafe control actions, and 129 unsafe scenarios. We conclude that STPA is an effective and efficient approach to derive detailed safety constraints. STPA can support the functional safety engineers to evaluate the architectural design of fully automated vehicles and build the functional safety concept.
