Abstract. Security testing can broadly be described as (1) the testing of security requirements that concerns confidentiality, integrity, availability, authentication, authorization, nonrepudiation and (2) the testing of the software to validate how much it can withstand an attack. Agile testing involves immediately integrating changes into the main system, continuously testing all changes and updating test cases to be able to run a regression test at any time to verify that changes have not broken existing functionality. Software companies have a challenge to systematically apply security testing in their processes nowadays. There is a lack of guidelines in practice as well as empirical studies in real-world projects on agile security testing; industry in general needs a more systematic approach to security. The findings of this research are not surprising, but at the same time are alarming. The lack of knowledge on security by agile teams in general, the large dependency on incidental pen-testers, and the ignorance in static testing for security are indicators that security testing is highly under addressed and that more efforts should be addressed to security testing in agile teams.

Over the past few decades, the automotive industry was mostly focused on testing the safety aspects of a vehicle. However, this was not the case with security testing as it only began to be addressed recently. As a result, multiple approaches applying various security testing techniques on different software-based vehicle IT components emerged. With that said, the research and practice lack an overview about these techniques. In this paper, we conduct a systematic mapping study. This involved the investigation on the following five dimensions: (1) security testing techniques, (2) AUTOSAR layers, (3) functional interfaces of AUTOSAR, (4) vehicle lifecycle phases and (5) attacks. In total, 39 papers presenting approaches for security testing in automotive engineering were systematically selected and classified. The results identify multiple security testing techniques focusing on early phases of vehicle life cycle through the application and services layer of the AUTOSAR architecture. Finally, there is a need for security regression testing approaches, as well as combined security and safety testing approaches. CCS CONCEPTS• Security and privacy → Distributed systems security;
