The ISO 21434 is a new standard that has been proposed to address the future challenges of automotive cybersecurity. This white paper takes a closer look at the ISO 21434 helping engineers to understand the ISO 21434 parts, the key activities to be carried out and the main artefacts that shall be produced. As any certification, obtaining the ISO 21434 certification can be daunting at first sight. Engineers have to deploy processes that include several security risk assessment methods to produce security arguments and evidence supporting item security claims. In this white paper, we propose a security engineering approach that can ease this process by relying on Rigorous Security Assessments and Incremental Assessment Maintenance methods supported by automation. We demonstrate by example that the proposed approach can greatly increase the quality of the produced artefacts, the efficiency to produce them, as well as enable continuous security assessment. Finally, we point out some key research directions that we are investigating to fully realize the proposed approach.
Temporal epistemic logic is a well-established framework for expressing agents knowledge and how it evolves over time. Within language-based security these are central issues, for instance in the context of declassification. We propose to bring these
Despite widespread use of smartphones, there is no measurement standard targeted at smartphone security behaviors. In this paper we translate a well-known cybersecurity behavioral scale into the smartphone domain and show that we can improve on this
Due to their interesting features, blockchains have become popular in recent years. They are full-stack systems where security is a critical factor for their success. The main focus of this work is to systematize knowledge about security and privacy
Healthcare blockchains provide an innovative way to store healthcare information, execute healthcare transactions, and build trust for healthcare data sharing and data integration in a decentralized open healthcare network environment. Although the h
Security metrics present the security level of a system or a network in both qualitative and quantitative ways. In general, security metrics are used to assess the security level of a system and to achieve security goals. There are a lot of security
