Towards Identifying and closing Gaps in Assurance of autonomous Road vehicleS - a collection of Technical Notes Part 1
This report provides an introduction and overview of the Technical Topic Notes (TTNs) produced in the Towards Identifying and closing Gaps in Assurance of autonomous Road vehicleS (Tigars) project. These notes aim to support the development and evaluation of autonomous vehicles. Part 1 addresses: Assurance-overview and issues, Resilience and Safety Requirements, Open Systems Perspective and Formal Verification and Static Analysis of ML Systems. Part 2: Simulation and Dynamic Testing, Defence in Depth and Diversity, Security-Informed Safety Analysis, Standards and Guidelines
Early evaluation of security functionality in software projects - some experience on using the common criteria in a quality management process
This paper documents the experiences of assurance evaluation during the early stage of a large software development project. This project researches, contracts and integrates privacy-respecting software to business environments. While assurance evaluation with ISO 15408 Common Criteria (CC) within the certification schemes is done after a system has been completed, our approach executes evaluation during the early phases of the software life cycle. The promise is to increase quality and to reduce testing and fault removal costs for later phases of the development process. First results from the still-ongoing project suggests that the Common Criteria can define a framework for assurance evaluation in ongoing development projects.Dieses Papier dokumentiert den Versuch, mittels der Common Criteria nach ISO 15408 bereits während der Erstellung eines Softwaresystems dessen Sicherheitseigenschaften zu überprüfen. Dies geschieht im Gegensatz zur üblichen Post-Entwicklungs-Evaluation
An Assurance Framework for Independent Co-assurance of Safety and Security
Integrated safety and security assurance for complex systems is difficult for
many technical and socio-technical reasons such as mismatched processes,
inadequate information, differing use of language and philosophies, etc.. Many
co-assurance techniques rely on disregarding some of these challenges in order
to present a unified methodology. Even with this simplification, no methodology
has been widely adopted primarily because this approach is unrealistic when met
with the complexity of real-world system development.
This paper presents an alternate approach by providing a Safety-Security
Assurance Framework (SSAF) based on a core set of assurance principles. This is
done so that safety and security can be co-assured independently, as opposed to
unified co-assurance which has been shown to have significant drawbacks. This
also allows for separate processes and expertise from practitioners in each
domain. With this structure, the focus is shifted from simplified unification
to integration through exchanging the correct information at the right time
using synchronisation activities

Disruptive Innovations and Disruptive Assurance: Assuring Machine Learning and Autonomy
Autonomous and machine learning-based systems are disruptive innovations and thus require a corresponding disruptive assurance strategy. We offer an overview of a framework based on claims, arguments, and evidence aimed at addressing these systems and use it to identify specific gaps, challenges, and potential solutions
